PRODUCT DESCRIPTION
POWER CONNECTIONS
The JL Audio 1000/1 is a monoblock subwoofer
amplifier utilizing proprietary and patented Class D
technology. Its frequency response is limited to the
range below 250 Hz. It is not designed
for driving midrange speakers or tweeters.
Every aspect of its operation has been optimized
for low-frequency amplification. For detailed
specifications, please refer to Appendix E (page 21).
7) Securely mount the amplifier using the
supplied screws.
8) Connect the positive and negative power
wires to the amplifier.A fuse near the amplifier is
not necessary.
9) Connect the remote turn-on wire to
the amplifier.
10) Connect the RCA input cables to
the amplifier.
11) Connect the speaker wires to the amplifier.
12) Carefully review the amplifier’s control
settings to make sure that they are set according to
the needs of the system.
13) Install power wire fuse (100A for a single
1000/1) and reconnect the negative battery
post terminal.
14) Turn on the source unit at a low level
to double-check that the amplifier is configured
correctly. Resist the temptation to crank it up until
you have verified the control settings.
15) Make necessary adjustments to the input
sensitivity control to obtain the right overall output
and the desired balance between the subwoofer
output and the satellite (mid and high-frequency)
output. See Appendix B (page 14) for the
recommended input sensitivity setting method.
16) Enjoy the fruits of your labor with your
favorite music.
Before installing the amplifier, disconnect the
negative (ground) wire from the vehicle's battery.
This will prevent accidental damage to the system,
the vehicle and your person during installation.
Any wires run through metal barriers (such as
firewalls), must be protected with a high quality
rubber grommet to prevent damage to the
insulation of the wire. Failure to do so may result in
a dangerous short circuit.
+12VDC
Ground Remote
IMPORTANT
!
Many vehicles employ small (10 AWG -
6 AWG) wire to ground the battery to the
vehicle chassis and to connect the alternator's
positive connection to the battery.To prevent
voltage drops, these wires should be upgraded to
4 AWG (or larger) when installing amplifier
systems with total fuse ratings exceeding 60A.
TYPICAL INSTALLATION SEQUENCE
The following represents the sequence for a
typical amplifier installation, using an aftermarket
source unit. Additional steps and different
procedures may be required in some applications.
If you have any questions, please contact your
authorized JLAudio dealer for assistance.
The 1000/1's “+12VDC” and “Ground”
connections are designed to accept 4 AWG power
wire. 4 AWG is the only recommended
power wire size for this amplifier.
If you are installing the 1000/1 with other
amplifiers and wish to use a single main power wire,
use 2 AWG or 1/0 AWG main power wire
(depending on the overall current demands of all
the amplifiers in the system).This 2 AWG or
1/0 AWG power wire should terminate into a
distribution block mounted as close to the amplifiers
as possible and should connect to the 1000/1 with
4 AWG power wire.
Please note that smaller AWG numbers mean
bigger wire and vice-versa (1/0 AWG is biggest,
2 AWG is smaller, then 4 AWG, then 8 AWG, etc.).
To connect the power wires to the amplifier,
first back out the set screw on the top of the
amplifier, using the supplied 2.5 mm hex wrench.
Strip 1/2 inch (12 mm) of insulation from the end
of each wire and insert the bare wire into the
receptacle on the front panel of the amplifier,
seating it firmly so that no bare wire is exposed.
While holding the wire in place, tighten the set
screw firmly, taking care not to strip the head
of the screw.
The ground connection should be made using
the same gauge wire as the power connection
and should be kept as short as possible, while
accessing a solid piece of sheet metal in the vehicle.
The surface of the sheet metal should be sanded at
the contact point to create a clean, metal-to-metal
connection between the chassis and the termination
of the ground wire.The use of a star washer to lock
down the connection is advisable.
FUSE REQUIREMENTS
It is absolutely vital that the main power
lead to the amplifier(s) in the system be fused
within 18 inches (45 cm) of the positive battery
post connection.The fuse value at each power
wire should be high enough for all of the
equipment being run from that power wire.
If only the 1000/1 is being run from that power
wire, we recommend a 100A ANL (large blade-
type fuse pictured below) be used.
1) Disconnect the negative battery post
connection and secure the disconnected cable to
prevent accidental re-connection during installation.
This step is not optional!
2) Run power wire (minimum 4 AWG) from
the battery location to the amplifier mounting
location, taking care to route it in such a way that
it will not be damaged and will not interfere
with vehicle operation. Use 2 AWG or 1/0 AWG
power wire if additional amplifiers are being
installed with the 1000/1.
3) Connect power wire to the positive battery
post. Fuse the wire with an appropriate fuse block
(and connectors) within 18 inches (45 cm) wire
length of the positive battery post. This fuse is
essential to protect the vehicle. Do not install
the fuse until the power wire has been
connected to the amplifier.
4) Run signal cables (RCA cables) and remote
turn-on wire from the source unit to the amplifier
mounting location.
No fuse is required directly before the amplifier
power connection. If one is desired at this
location, we recommend the use of a 100A ANL
fuse for each 1000/1.
5) Run speaker wire from the speaker system to
the amplifier mounting location.
6) Find a good, solid metal grounding point close
to the amplifier and connect the negative power
wire to it using appropriate hardware. Use the same
size power wire as the wire connected to the
“+12V” connection (min. 4 AWG), no longer than
36 inches (90 cm) from the amplifier to the ground
connection point. In some vehicles, it may be
necessary to upgrade the battery ground wire.

REMOTETURN-ON
AMPLIFIER INPUT SECTION
CROSSOVER CONTROLS
The 1000/1 uses a conventional +12V remote
turn-on lead, typically controlled by the source unit's
remote turn-on output.The amplifier will turn on
when +12V is present at its “Remote” input and
turn off when +12V is switched off. If a source unit
does not have a dedicated remote turn-on output,
the amplifier’s turn-on lead can be connected to
+12V via a switch that derives power from an
ignition-switched circuit.
The 1000/1's “Remote” turn-on connector is
designed to accept 12 AWG – 8 AWG wire.
12 AWG is more than adequate for this purpose.
To connect the remote turn-on wire to the
amplifier, first back out the set screw on the top of
the amplifier, using the supplied hex wrench. Strip
1/2 inch (12mm) of wire and insert the bare wire
into the receptacle on the front panel of the
amplifier, seating it firmly so that no bare wire is
exposed. Smaller wire than 12 AWG can be used,
but it may be necessary to strip 1 inch of insulation
from the wire and fold the bare wire in half prior to
insertion.While holding the wire in the terminal,
tighten the set screw firmly, taking care not to strip
the head of the screw and making sure that the
wire is firmly gripped by the set screw.
The 1000/1 employs a differential-balanced
input topology that provides the user with a high
degree of input flexibility while retaining superior
noise rejection.This type of circuit also allows the
1000/1 to accept high-voltage inputs from factory
source unit outputs without excessive distortion
or noise problems.
window. If you are using an aftermarket source
unit, with conventional preamp-level outputs, this
is most likely the position that you will use.
The “High” position on the “InputVoltage”
switch selects an input sensitivity range between
800mV and 8V. This is useful for certain high-
output preamp level signals as well as speaker-level
output from source units and small amplifiers.To
use speaker-level sources, splice the speaker output
wires of the source unit or small amplifier onto a
pair of RCA cables or plugs.
Crossovers are groups of individual electronic filters
which allow only certain frequency ranges to pass
through them by attenuating frequencies outside
the selected range.These filters allow the user to
specify what frequency range will be sent out of
each channel section of the amplifier.This, in turn,
allows each speaker system to only reproduce a
range of frequencies it is well-suited for, resulting in
reduced distortion and improved fidelity.
AMPLIFIER LOW-PASS FILTER
Low/High
The 1000/1 employs a sophisticated, state-variable,
low-pass active filter for its internal channel.This
feature is designed to attenuate frequencies above its
filter frequency, so that the system's subwoofers do
not reproduce any audible midrange content.
IMPORTANT
!
The output of the amplifier will decrease for a
given input voltage when the “Input Range” switch
is placed in the “High” position. Conversely, the
output will be higher with the switch in the “Low”
position.While this may sound counter-intuitive, it is
consistent with the descriptions above.
3) Input Sensitivity Adjustment: Located next to
the “InputVoltage” switch, in the “Amplifier Input
Section”, is a rotary control labeled “Input Sens.”.
Once the appropriate “InputVoltage” range has
been selected, this rotary control can be used to
match the source unit's output voltage to the input
stage of the amplifier for maximum clean output.
Rotating the control clockwise will result in higher
sensitivity (louder for a given input voltage).
Rotating the control counter-clockwise will result in
lower sensitivity (quieter for a given input voltage).
To properly set the amplifier for maximum clean
output, please refer to Appendix B (page 14) in this
manual.After using this procedure, you can then
adjust the level of the amplifier by adjusting the
input sensitivity downward, if the amplifier requires
attenuation to achieve the desired system balance.
Do not increase the “Input Sens.” setting for
any amplifier in the system beyond the maximum
level established during the procedure outlined
in Appendix B (page 14). Doing so will result in
audible distortion and possible speaker damage.
1) Input Connections: A standard left/right
pair of RCA type jacks is used for input on
the 1000/1.You may run a stereo or a mono
signal into the inputs of the amplifier.The
amplifier's input section automatically sums
stereo signals to mono for the internal amplifier
section and for the “LP” “Filter Mode” of the
“Preamp Output” section.
IMPORTANT
!
1) Filter Operation:The low-pass filter in the
1000/1 is fully variable between 40 Hz and 200 Hz
via the “Filter Freq.” control knob and features the
ability to select between a moderate “12dB” per
octave or a steep “24dB” per octave slope via the
“Mode/Slope” switch.
Depending on the subwoofer system and the
vehicle, different slopes may be required to produce
a smooth transition to the mid-bass speakers in the
system. Experiment to find the slope which best
matches the acoustic requirements of your system.
Hint: A trunk mounted sub whose output has to
"fight" through a rear deck or a back seat often
benefits from the 12 dB/octave slope which lets
more upper bass content pass through.A sub that
fires directly into the listening environment is more
likely to benefit from a 24 dB/octave slope.
If you plan to use the “Preamp Output” of the
1000/1 to feed a stereo amplifier, you must connect
a stereo signal to the input of the amplifier. A mono
signal into the amplifier will result in a mono signal
out of the preamp output. (It's a great amplifier, but
it doesn't do magic).
The amplifier will operate with only one input
connection (left or right), but will require an
increase in input sensitivity to overcome the loss
of signal. If a mono input signal is to be run, we
recommend that you use a “Y-adaptor” to split the
mono signal into both inputs of the amplifier.
2) InputVoltage Range: A wide range of signal
input voltages can be accommodated by the
1000/1's input section (200mV – 8V).This wide
range is split up into two sub-ranges, accessible via
switches located in the “Amplifier Input Section”
of the amplifier.
The “Low” position on the “InputVoltage”
switch selects an input sensitivity range between
200mV and 2V. This means that the “Input Sens.”
rotary control will operate within that voltage

PREAMP OUTPUT SECTION
The 1000/1 incorporates a flexible preamp
output section, designed to make multiple amplifier
systems easy to set up.
The Preamp output can be configured in three
different “Output Modes”:
The above hint is not “set-in-stone”…
This is completely independent of the amplifier’s
internal filter and allows the user to match, stagger
or overlap the subwoofer low-pass filter frequency
of the amplifier crossover with the output filter’s
frequency for precise control and optimized
midbass performance.
If you would like to select the filter frequency
with a higher level of precision, consult
Appendix A: Chart A-2 (page 12) of this manual.
If you would like to select the infrasonic filter
frequency with a higher level of precision, consult
Appendix A: Chart A-3 (page 13) of this manual.
The infrasonic filter can be completely defeated
by selecting the “Off” position on the “Mode”
switch.This bypasses all signal from flowing
through the circuit.
2) Parametric Bass Equalizer: The parametric
equalizer allows the used to select the center
frequency of the boost band as well as the
bandwidth (“Q”) of the boost band.
You should always listen to the system carefully to
determine the best choice as vehicle acoustics and
other factors play a big role in choosing the most
appropriate filter slope.
2) Precise Frequency Selection:The filter
frequency markings on the front panel of the
amplifier are for reference purposes and are
generally accurate to within 1/3 octave or better.
If you would like to select the filter frequency with
a higher level of precision, consult Appendix A:
Chart A-1 (page 12) of this manual.This chart
gives you a more accurate frequency for each of
the forty detented positions of the frequency
selection control.This method can be very useful if
the amplifier is mounted in a location where you
can’t see the front panel markings easily.
3) Defeating the Amplifier Filter: The Low-
Pass filter can also be defeated completely, by
switching the “Mode/Slope” switch to the “Off”
position.This is useful if you are using an external
active crossover in the system. Keep in mind that
turning the internal crossover off also defeats the
“Advanced Bass Control” section processing
(see page 9 for details).With the internal
crossover turned off, the 1000/1’s upper
CAUTION
!!
The “Q" control selects the bandwidth of the
boost around the center frequency. Lower numbers
pertain to wider bandwidths while higher number
pertain to narrower bandwidths.
The signal level of the “Preamp Output” is
affected by the setting of the “InputVoltage Range”
switch (of the input section chosen by the
“Signal From” switch). See Appendix B (page 14)
for details on “InputVoltage” settings. All “slave”
amplifiers should get this switch set to “Low”.
See Appendix C (page 16) for details.
1) “Full-Range”:This is a pass-through mode
for the preamp output, delivering the same signal
that is being fed to the “Amplifier Input Section”
(If the input signal is full-range, the preamp output
will be full-range).This signal is not affected by the
“Advanced Bass Control” processing selected
for the amplifier.
2) “Amp Filter”: The preamp output delivers
the same signal that is feeding the 1000/1’s
amplifier section, including all the processing
induced by the “Amp LP Filter” and “Advanced
Bass Control” sections. This is primarily used for
running additional 1000/1’s in a “Slave”
The “Center Freq.” control selects the center
frequency of the boost bandwidth within a range of
20 - 80 Hz. If you would like to select the filter
frequency with a higher level of precision, consult
Appendix A: Chart A-4 (page 13) of this manual.
The “Boost” control determines how much
boost (in dB) you are adding to the bass signal.
A range of 0 - 15dB of boost is available.
The “Remote Bass Port” allows the connection
of an optional remote boost knob (the RBC-1)
that can be mounted in the front of the vehicle.
This optional control takes the place of the
“Boost” knob on the amplifier when connected
and bypasses the “Boost” control on the amplifier.
ADVANCED BASS CONTROL SECTION
The 1000/1 includes a versitile bass processing
section consisting of two primary components: a
fully variable, 24 dB per octave infrasonic filter and a
parametric, single-band equalizer.
frequency response limit is 250 Hz, due to its
bass-specific Class D design.
configuration from the “Master” amplifier. For
detailed information on Master/Slave
configurations, see Appendix C (page 16). If the
“Output Mode” switch is in the “Amp Filter”
position and the “Amp LP Filter” switch is in the
“Off” position, there will be no output from the
preamp output jacks.The independent output filter
controls (“Filter Slope”, “Filter Freq” and “Filter
Mode”) are inactive in “Amp Filter” mode.
3) “Out Filter”:The preamp output is filtered by
a fully variable, active filter incorporated into the
output section and is not affected by the bass
control processing selected for the amplifier.
In “Out Filter” mode, the user can select:
a) High-pass (“HP”) or low-pass (“LP”) filtering by
way of the “Filter Mode” switch.
IMPORTANT
!
The “Advanced Bass Control” section will only
operate when the amplifier's filter is activated with
the “Amp LP Filter” switch in the “12dB” or
“24dB” position. It will not work with this switch in
the “Off” position.This is to prevent cascading the
processing of multiple amplifiers when configured
in a master/slave arrangement as shown in
Appendix C (page 16). If you are using an external
active crossover and would like to use the
“Advanced Bass Control” features, set the
“Amp LP Filter” switch on “12dB” and rotate the
frequency selection knob fully clockwise to the
“200 Hz” position.This will activate the “LF Boost”
and “Infrasonic Filter” controls without significantly
affecting the crossover point selected by the
external active crossover.
1) “Infrasonic Filter”:The infrasonic filter is a
24 dB/octave high-pass filter, with a fully variable
cutoff frequency between 15 - 60 Hz.When set at
frequencies lower than 30 Hz, it conserves amplifier
power without audibly affecting the quality of the
sub-bass output. If set at frequencies higher that
30 Hz, there will be an audible effect, but one which
may be desirable for SPL competition purposes or
curve shaping of a bottom-heavy system.
b) 12 dB/octave or 24 dB/ octave filter slope by way
of the “Filter Slope” switch.
c) A filter cutoff frequency between 40 - 200 Hz for
the preamp output signal by way of the “Filter
Control” switch.
With ported enclosures, the use of the
infrasonic filter is highly recommended to protect
the speaker(s) from excessive excursion below
box tuning.With sealed enclosures, the use of the
filter is less necessary, but can still help protect the
speaker system.

connections.This is to facilitate multiple speaker
wiring.The two positive and two negative
connections are connected in parallel inside the
amplifier. Connecting two speakers, each to one set
of positive and negative terminals, will result in a
parallel speaker connection. If only connecting one
pair of speaker wires, it is not necessary to use
both sets of connections.

the amplifier power connections may minimize
short-duration voltage dips in systems that are
having this problem.
Keep in mind that any large amplifier, like the
1000/1, places a very heavy demand on a vehicle’s
charging system when operated at its limits.Vehicles
with weak charging systems may need to be
serviced and/or upgraded to provide ample current
to a system including a 1000/1.
STATUS INDICATOR LIGHTS /
PROTECTION CIRCUITRY
There are three status indicator lights on the top
of the amplifier. These are as follows:
1) “Power” (Green): lights to indicate that the
amplifier is turned on and operating normally.
2) “Thermal” (Red): lights to indicate that the
amplifier has exceeded its safe operating
SUBWOOFER OUTPUT
The 1000/1 employs JL Audio's exclusive
Regulated, Intelligent Power Supply (R.I.P.S.) design.
This sophisticated power supply allows the amplifier
to produce its optimum power (1000 watts x 1)
over a wide range of speaker impedances.
Unlike conventional amplifiers that require a
specific impedance to produce optimum power, the
R.I.P.S.-equipped 1000/1 gives you the freedom to
use a variety of subwoofer configurations that
achieve final nominal impedances between
1.5 – 4Ω (without sacrificing power output or
sound quality).
The operation of the R.I.P.S. circuitry is entirely
automatic and adjusts itself every time the amplifier
is turned on according to the lowest impedance
present at the speaker load.There are no user
controls to configure.The system operates through
multiple stages of impedance optimization, choosing
the stage most appropriate to the actual impedance
of the speaker(s) you connect to it.
For information on troubleshooting this
amplifier, refer to Appendix D (page 18).
The 1000/1's speaker connectors are designed
to accept 12 AWG – 8 AWG wire.
temperature, putting the amplifier into a self-
protection mode, which reduces the power output
of the amplifier. The red light will shut off and the
amplifier will return to normal, full-power operating
mode if the heat sink temperature drops back to a
safe level.
3) “Low Ω” (Amber): lights to indicate that the
impedance of the speaker load connected to the
amplifier is lower than the optimum load impedance
range for the amplifier.When this light is on, a
protection circuit engages and reduces the power
output of the amplifier.The amber indicator will also
light when a short-circuit is detected in the speaker
wiring (this can be a short between the positive and
negative speaker wires or between either speaker
wire and the vehicle chassis).
4) “LowV” (Blue): lights to indicate any dip in
supply voltage below 8 volts.The blue LED will
remain lit longer than the dip duration to better
alert the user to the problem. This will be
accompanied by a shutdown of the amplifier
(green LED will shut off) and a total loss of
output. Once the voltage rises above 9 volts,
the amplifier will turn itself on. Because voltage
dips occur in rapid succession, the typical behavior
will be a cycling of the amplifier on and off,
accompanied by flashing of the “LowV” blue LED.
If this is happening in your system, you will need to
investigate the cause of the voltage problem.This
could be a bad ground on the amplifier, battery or
alternator OR a faulty battery/charging system OR
a problem with a fuse holder or wire connection.
If you are unsure as to the cause of the problem,
please consult your JLAudiodealer or a qualified
automotive electrical specialist.
SERVICINGYOUR JL AUDIO AMPLIFIER
If your amplifier fails or malfunctions, please
return it to your authorized JL Audio dealer so
that it may be sent in to JL Audio for service.
There are no user serviceable parts or fuses
inside the amplifier.The unique nature of the
circuitry in the JL Audio amplifiers requires
specifically trained service personnel. Do not
attempt to service the amplifier yourself or
through unauthorized repair facilities.This will not
only void the warranty, but may result in the
creation of more problems within the amplifier.
To connect the speaker wires to the amplifier,
first back out the set screws on the top of the
amplifier, using the supplied 2.5 mm hex wrench.
Strip 1/2 inch (12 mm) of insulation from each
wire and insert the bare wire end into the
receptacles on the front panel of the amplifier,
seating them firmly so that no bare wire is
exposed.While holding each wire in place, tighten
each set screw firmly, taking care not to strip the
head of the screw and making sure that the wire
is firmly gripped by the set screw.
If you have any questions about the installation or
setup of the amplifier not covered in
this manual, please contact your dealer or the
JL AUDIO Technical Department for assistance:

IMPORTANT
!
Do NOT attempt to “bridge” two 1000/1’s or
combine their output to a single load in any
manner. Doing so will damage the amplifier(s).

Monday – Friday
IMPORTANT
!
If you connect a load higher than 4Ω nominal
to the 1000/1, power will drop by half with every
doubling of impedance above 4Ω. If you connect a
load lower than 1.5Ω nominal to the 1000/1, the
amplifier protection circuitry activates a “safe”
mode which reduces amplifier power to protect
the circuitry from failure (the yellow LED on the
top of the amplifier will light to indicate that this
has happened). See page 11 for details.
Before reconnecting the battery ground and
turning the system on, verify that all control
settings on the amplifier are set according to the
needs of the system.
OUTPUT POLARITY SWITCH
Depending on the distance relationship of the
mid-bass speakers and the subwoofers in a
system, it can be desirable to reverse the polarity
of the subwoofer system in order to produce a
better transition between subwoofer and mid-
bass speaker output.The “Output Polarity” switch
allows you to peform this polarity inversion
without removing any wires. Simply flip the switch
from the “Normal” to the “Reversed” position.
Experiment with this switch to determine which
polarity produces the best overall bass
IMPORTANT
!
Speaker loads below 1.5Ω nominal are not
recommended and may cause the amplifier output
to distort excessively.
Speaker connections to the 1000/1 are
straightforward and take place at the far right of
the front panel.You will notice that there are two
“+” positive connections and two “–” negative

APPENDIX B:
Input Sensitivity Level Setting
JLAudio amplifiers utilizing the Regulated
Intelligent Power Supply (R.I.P.S.) allow delivery of
their rated power when connected to any load
impedance from 1.5 - 4Ω per channel and when
connected to a charging system with any voltage
from 11 - 14.5V. This design is beneficial for many
reasons. One of these reasons is ease of setup.
Because each JLAudio amplifier will always deliver
the same amount of power within its operational
range of impedances and supply voltages, the
maximum, unclipped output is very predictable.
This makes setting the gain structure via the input
sensitivity controls very simple. Following the
directions below will allow the user to adjust the
input sensitivity of the amplifier(s) simply and easily
in just a few minutes using equipment which is
commonly available in installation bays.
5) Using the chart below, determine the target
voltage for input sensitivity adjustment according to
the nominal impedance of the speaker system
connected to the amplifier output.
Nom. Impedance
Target ACVoltage
4Ω (or higher)
63.2V
54.7V
44.7V
38.7V
3Ω
2Ω
1.5Ω
6)Verify that you have disconnected the
speakers before proceeding. Play a track with an
appropriate sine wave (within the frequency range
to be amplified) at 3/4 source unit volume.
7) Connect the AC voltmeter to the
“Subwoofer Output” connectors of the amplifier.
8) Increase the “Input Sens.” control until the
target voltage is delivered. If multiple subwoofer
amps are being used, set each one to the same
exact voltage and you have also level matched
them. If excessive voltage is read with the control
at minimum (full counterclockwise), switch the
“InputVoltage” to “High” and re-adjust.
Necessary Equipment
• Digital ACVoltmeter
• CD with a sine-wave test tone recorded at 0 dB
reference level in the frequency range to be
amplified (ex. 50 Hz for a subwoofer amplifier.
1 kHz for a midrange application). Do not use
attenuated test tones (-10 dB, -20 dB, etc.).
9) Once you have adjusted each amplifier to its
maximum unclipped output level, reconnect the
speaker(s).The “Input Sens.” can now be adjusted
downward if the amplifier requires attenuation to
achieve the desired system balance.
The Nine-Step Procedure
1) Disconnect the speaker(s) from the amplifier’s
“Subwoofer Output”connectors (you only need to
remove the negative or positive speaker wire).
2)Turn “Off” all processing on the source unit
and amplifier (bass/treble, loudness, EQ, etc.).
3) Switch the “InputVoltage” to “Low” and
turn the “Input Sens.” control on the amplifier all
the way down.
IMPORTANT
!
Do not increase any “Input Sens.” setting in
the system beyond the maximum level established
during this procedure. Doing so will result in
audible distortion and possible speaker damage.
4) Set the source unit volume to 3/4 of full
volume. If the amplifier is being driven by a source
unit’s dedicated subwoofer output, also adjust the
source unit’s subwoofer level control to 3/4 of
maximum output.This will allow for reasonable gain
overlap with moderate clipping at full volume.

APPENDIX C:
Master/Slave Configurations
With the flexible on-board crossovers and
processing incorporated into the 1000/1, it is
possible to connect multiple 1000/1’s in a
“Master/Slave” configuration, with each amplifier
driving its own speaker system but controlled by
the processing and filtering of only one amplifier.
This is very useful when driving multiple
subwoofers with multiple amplifiers.
To create a Master/Slave configuration, first
determine which amplifier will be the “Master”
amplifier and connect the main input signal to that
amplifier (from the source unit or from an
outboard processor).This amplifier’s “Amp LP
Filter” section and “Advanced Bass Control”
features will process the signal for the “Slave”
amplifier or amplifiers.
2) Connect an RCA cable from the “Master”
amplifier’s preamp outputs to the main input of the
first “Slave” amplifier. Set the “Slave” amplifier’s
“Amp LP Filter” to the “Off” position.This will
defeat the LP filter and the bass processing of this
“Slave Amplifier”.
3)The input sensitivity of the two amplifiers
needs to be adjusted independently.To properly
calibrate the amplifiers for maximum, identical, clean
output, please refer to Appendix B (page 14).
After using this procedure, you can then adjust the
level of the amplifiers by adjusting the input
sensitivities downward, if the amplifiers require
attenuation to achieve the desired system balance.
If the input sensitivities are adjusted, the amplifiers
must be recalibrated to ensure identical power
output levels.
out of the preamp outputs of the amplifier are
compatible with the “Low” setting on the
“Input Range” control.
The “Signal Sensing” turn-on feature will not
work on “slave” amplifiers, but “slave” amplifiers
can be turned on and off by a “master” amplifier
operating in signal sensing turn-on mode.
Simply connect the “master” amplifier’s
first “Slave” amplifier, set the second “Slave”
amplifier’s “Amp LP Filter” to the “Off” position.
Then, calibrate the third amplifier’s “Input Range”
and “Input Sens.” controls in the same manner as
you did for the second amplifier.
Additional amplifiers may be added to this
“Master/Slave” configuration following the same
procedure as in step 4.
“Remote” connection, to the “slave” amplifier(s)
“Remote” connection(s).
Once you match the input sensitivities of all the
amplifiers, you can use the “Master” amplifier’s
“Amp LP Filter” and “Advanced Bass Control”
features to control the “Slave” amplifier(s). If the
remote bass control (RBC-1) is used, it need only
be connected to the “Master” amplifier to control
all the amplifiers in the Master/Slave chain.
Below is a diagram showing a Master/Slave
configuration with one “Master” (top amplifier)
and two “Slave” amplifiers. Switches and controls
that are defeated in the “Slave” amplifiers are
printed in gray.
Do not increase the “Input Sens.” setting for any
amplifier in the system beyond the maximum level
established during the procedure outlined in
Appendix B (page 14). Doing so will result in
audible distortion and possible speaker damage.
4) If you would like to run a third amplifier in
“Slave” configuration, select the “Full-Range”
position on the “Output Mode” switch of the first
“Slave” amplifier.Then, connect an RCA cable
from the first “Slave” amplifier’s preamp outputs to
the second “Slave” amplifier. As you did with the
Here is the procedure for implementing a
“Master/Slave” configuration:
Please note that the “Input Range” switch on
all “slave” amplifiers needs to be set to “Low”,
even if the “master” amplifier is high voltage and
its switch is set to “High”. All signals passed
1) Set the “Master” amplifier’s “Output Mode”
switch to the center “Amp Filter” position.This will
send a parallel, mono-summed signal from the
“Master” amplifier’s “Amp LP Filter” section to its
preamp outputs.

APPENDIX D: TROUBLE SHOOTING
“MY AMPLIFIER DOESN’TTURN ON”
“MY AMPLIFIER SHUTS OFF ONCE IN AWHILE, USUALLY AT HIGHERVOLUMES”
Check your voltage source and grounding point.The R.I.P.S. power
supply is rated to operate with source voltages between
Check to make sure there is +12V at the “Remote” connection of
the amplifier. In some cases, the turn-on lead from the source
unit is insufficient to turn on multiple devices and the use of a
relay is required. To test for this problem, jump the “+12V”
wire to the “Remote” terminal to see if the amplifier turns on.
If this does not work, proceed to the next step.
11 - 14.5V. Shutdown problems at higher levels can occur
when the charging system voltage drops below 10-volts.These
dips can be of very short duration making them extremely
difficult to detect with a common DC voltmeter.To ensure
proper voltage, inspect all wiring and termination points. It is
also a good idea to improve the vehicle’s factory ground wire
and termination point. Grounding problems are the leading
cause of mis-diagnosed amplifier failures.
Check the fuse, not just visually but with a continuity meter. It is
possible for a fuse to have poor internal connections that
cannot be found by visual inspection. It is best to take the
fuse out of the holder for testing. If no problem is found
with the fuse, inspect the fuse-holder.
Check the “Signal Sensing” switch to make sure it is in the desired
position. If you are using a remote wire, this switch should be
in the “Off” position. If you are using the signal sensing
feature, make sure there is a full-range signal being sent to the
RCA inputs of the amplifier. If you continue to have trouble
with the signal sensing feature, test the amplifier’s ability to turn
on by throwing the “Signal Sensing” switch to the “Off”
position and jumping the “+12V” wire to the “Remote”
terminal. If this turns the amplifier on, check your input signal
and connections.
“MY AMPLIFIERTURNS ON, BUTTHERE IS NO OUTPUT”
Check the input signal using an AC voltmeter to measure the
voltage from the source unit while an appropriate test tone
is played through the source unit (disconnect the RCA
cables from the amplifier prior to this test).The frequency
used should be in the range that is to amplified by the
channels being tested (example: 50 Hz for a sub bass
amplifier channel and 1 kHz for a full-range amplifier
channel). A steady voltage should be present at the output
of the RCA cables. If you are receiving a sufficient voltage
(between 0.2 and 8.0-volts), check to ensure that the
speaker wires are making a good connection with the metal
inside the amplifier.The connectors are designed to accept
up to an 8 AWG wire. If you are using significantly smaller
wire (14 AWG or smaller), you may have difficulty making
an adequate connection. In this case, you may find it
necessary to “fold” the wire over once (or twice!) so as to
make a solid connection. Make sure to strip the wire to
allow for a sufficient connection with the input or output
of the amplifier.
“I GET A DISTORTED / ATTENUATED SOUND COMING OUT OFTHE SPEAKER(S)”
Check the speaker wires for a possible short, either between the
positive and negative or between a speaker lead and the
vehicle’s chassis ground. If a short is present you will
experience distorted and/or attenuated output.The
“Low Ω” light may also illuminate in this situation. It may be
helpful to disconnect the speaker wires from the amplifier
and use a different set of wires connected to a test speaker.
Check the nominal load impedance to verify that the amplifier is
driving a load between 1.5 - 4Ω. JLAudio monoblock
Check the output of the amplifier. Using the procedure explained in
the previous check item (after plugging the RCA cables back
into the amplifier) test for output at the speaker outputs of the
amplifier. Unless you enjoy test tones at high levels, it is a good
idea to remove the speaker wires from the amplifier while
doing this. Turn the volume up approximately half way.
5-volts or more should be measured at the speaker outputs.
This output level can vary greatly between amplifiers but it
should not be in the millivolt range with the source unit at half
volume. If you are reading sufficient voltage, check your speaker
connections as explained above.
amplifiers have two “+” positive connections and two “–”
negative connections.This is to facilitate multiple speaker wiring.
The two positive and two negative connections are connected
in parallel inside the amplifier. Connecting two speakers, each
to one set of positive and negative terminals, will result in a
parallel speaker connection. In this case, each of the two loads
should have a nominal impedance between 3 - 8Ω.
Check the input signal and input signal cables to make sure signal is
present at the “Amplifier Input Section” and the cables are
not pinched or loose. It may be helpful to try a different set of
cables and/or a different signal source to be sure.
