DESIGN FEATURES
1. Cast Aluminum Heatsink – The cast aluminum heatsink of the Punch amplifier dissipates heat
generated by the amplifier's circuitry. The inherent advantage of casting provides a 30%
improvement of cooling over conventional extrusion heatsink designs.
2. Variable Crossover – The amplifiers have a built-in 12dB/octave Butterworth filter with a
crossover point variable from 50Hz to 210Hz. The crossover can be set to Low-Pass (LP) or it
can be bypassed by setting it to All-Pass (AP).
3. RCA Input Jacks – The industry standard RCA jacks provide an easy connection for signal level
input. They are gold-plated to resist the signal degradation caused by corrosion.
4. Gain Control – The input gain control is preset to match the output of most source units. It can
be adjusted to match output levels from a variety of source units.
5. LED Power Indicator – The LED illuminates when the unit is turned on.
6. REM Terminal – This spade terminal is used to remotely turn-on and turn-off the amplifier when
+12V DC is applied.
7. Power Terminals – The power and ground connectors on the Punch amplifier are gold-plated
and will accommodate up to 8 AWG wire maximizing the input current capability of the
amplifier.
8. High Level Inputs – The high level inputs use a detachable connector terminated with 20 AWG
leads. These inputs should be used if the source unit has only speaker line (high level) outputs
and not RCA outputs.
9. Punch Bass – The Punch Bass control helps correct for acoustical deficiencies in the listening
environment by helping produce full range sound without adding excessive boost.. The Punch
Bass control is a narrow band adjustment at 45Hz switchable from 0dB to +6dB to +12dB.
10. Speaker Terminals – The heavy duty, gold-plated terminal block connectors (+ and –) will
accept wire sizes from 8 AWG to 18 AWG. These gold-plated connectors are immune to
corrosion that can cause signal deterioration.

INSTALLATION
This section focuses on some of the vehicle considerations for installing your new Amplifier. Pre-
planning your system layout and best wiring routes will save installation time. When deciding on
the layout of your new system, be sure that each component will be easily accessible for making
adjustments.
CAUTION: If you feel unsure about installing this system yourself, have it installed
!
by a qualified technician.
CAUTION: Before installation, disconnect the battery negative (-) terminal to
!
prevent damage to the unit, fire and/or possible injury.
Before beginning any installation, follow these simple rules:
1. Be sure to carefully read and understand the instructions before attempting to install the Unit.
2. For safety, disconnect the negative lead from the battery prior to beginning the installation.
3. For easier assembly, we suggest you run all wires prior to mounting your Source Unit in place.
4. Route all of the RCA cables close together and away from any high current wires.
5. Use high quality connectors for a reliable installation and to minimize signal or power loss.
6. Think before you drill! Be careful not to cut or drill into gas tanks, fuel lines, brake or hydraulic
lines, vacuum lines or electrical wiring when working on any vehicle.
7. Never run wires underneath the vehicle. Running the wires inside the vehicle provides the best
protection.
8. Avoid running wires over or through sharp edges. Use rubber or plastic grommets to protect any
wires routed through metal, especially the firewall.
9. ALWAYS protect the battery and electrical system from damage with proper fusing. Install the
appropriate fuse holder and fuse on the +12V power wire within 18” (45.7 cm) of the battery
terminal.
10. When grounding to the chassis of the vehicle, scrape all paint from the metal to ensure a good,
clean ground connection. Grounding connections should be as short as possible and always be
connected to metal that is welded to the main body, or chassis, of the vehicle.
MOUNTING LOCATIONS
The mounting position of your amplified subwoofer will have a great effect on the sound
performance produced.
Engine Compartment
Never mount this unit in the engine compartment. Mounting the unit in the engine compartment
will void your warranty.
Trunk Mounting
Mounting the amplifier vertically will provide the best cooling of the amplifier.
Mounting the amplifier on the floor of the trunk will work but provides less cooling capability than
vertical mounting.
Mounting the amplifier upside down to the rear deck of the trunk will not provide proper cooling
and will severely affect the performance of the amplifier and is strongly not recommended.
Passenger Compartment Mounting
Mounting the amplifier in the passenger compartment will work as long as you provide a sufficient
amount of air for the amplifier to cool itself. If you are going to mount the amplifier under the seat
of the vehicle, you must have at least 1" (2.54cm) of air gap around the amplifier's heatsink.
Mounting the amplifier with less than 1" (2.54cm) of air gap around the amplifier's heatsink in the
passenger compartment will not provide proper cooling and will severely affect the performance of
the amplifier and is strongly not recommended.

INSTALLATION
BATTERY AND CHARGING
Amplifiers will put an increased load on the vehicle's battery and charging system. We recommend
checking your alternator and battery condition to ensure that the electrical system has enough
capacity to handle the increased load of your stereo system. Stock electrical systems which are in
good condition should be able to handle the extra load of any Rockford Fosgate amplifier without
problems, although battery and alternator life can be reduced slightly. To maximize the performance
of your amplifier, we suggest the use of a heavy duty battery and an energy storage capacitor.
WIRING THE SYSTEM
CAUTION: If you do not feel comfortable with wiring your new unit, please see
!
your local Authorized Rockford Fosgate Dealer for installation.
CAUTION: Before installation, disconnect the battery negative (-) terminal to
!
prevent damage to the unit, fire and/or possible injury.
CAUTION: Avoid running power wires near the low level input cables, antenna,
!
power leads, sensitive equipment or harnesses. The power wires carry
substantial current and could induce noise into the audio system.
1. Plan the wire routing. Keep RCA cables close together but isolated from the amplifier's power
cables and any high power auto accessories, especially electric motors. This is done to prevent
coupling the noise from radiated electrical fields into the audio signal. When feeding the wires
through the firewall or any metal barrier, protect them with plastic or rubber grommets to
prevent short circuits. Leave the wires long at this point to adjust for a precise fit at a later time.
2. Prepare the RED wire (power cable) for attachment to the amplifier by stripping 1/2" of
insulation from the end of the wire. Insert the bared wire into the B+ terminal and tighten the set
screw to secure the cable in place.
NOTE: The B+ cable MUST be fused 18" or less from the vehicle's battery. Install the fuseholder under
the hood and prepare the cable ends as stated above. Connections should be water tight.
3. Trim the RED wire (power cable) within 18" of the battery and strip1/2"of insulation from the
end of the wire. Cut the wire loop that is attached to the fuseholder in half and splice the fuse
into the power line using appropriate inline connectors. Use the section of cable that was
trimmed earlier and connect it to the other end of the fuseholder.
4. Strip 1/2" from the battery end of the power cable and crimp a large ring terminal to the cable.
Use the ring terminal to connect to the battery positive terminal. DO NOT install the fuse at this
time.
5. Prepare the BLACK wire (Ground cable) for attachment to the amplifier by stripping 1/2" of
insulation from the end of the wire. Insert the bared wire into the GND terminal and tighten the
set screw to secure the cable in place. Prepare the chassis ground by scraping any paint from
the metal surface and thoroughly clean the area of all dirt and grease. Strip the other end of the
wire and attach a ring connector. Fasten the cable to the chassis using a non-anodized screw
and a star washer.
6. Prepare the REM turn-on wire for connection to the amplifier by stripping 1/2" of insulation from
the wire end. Insert the bared wire into the REM terminal and tighten the set screw to secure the
cable into place. Connect the other end of the REM wire to a switched 12 volt positive source.
The switched voltage is usually taken from the source unit's accessory lead. If the source unit
does not have this output available, the recommended solution is to wire a mechanical switch
in line with a 12 volt source to activate the amplifier.
7. Securely mount the amplifier to the vehicle or amp rack. Be careful not to mount the amplifier
on cardboard or plastic panels. Doing so may enable the screws to pull out from the panel due
to road vibration or sudden vehicle stops.
8. Connect the source signal to the amplifier by plugging the RCA cables/high level inputs into the
input jacks at the amplifier.
9. Connect the speakers. Strip the speaker wires 1/2" and insert into the speaker terminal and
tighten the set screw to secure into place. Be sure to maintain proper speaker polarity. DO NOT
chassis ground any of the speaker leads as unstable operation may result.

INSTALLATION
10. Perform a final check of the completed system wiring to ensure that all connections are
accurate. Check all power and ground connections for frayed wires and loose connections
which could cause problems.
NOTE: Follow the diagrams for proper signal polarity.
CAUTION: These amplifiers are not recommended for impedance loads below 2Ω.

USING PASSIVE CROSSOVERS
A passive crossover is a circuit that uses
capacitors and/or coils and is placed on
speaker leads between the amplifier
and speaker. The crossover delegates a
specific range of frequencies to the
speaker for optimum driver
performance. A crossover network can
perform one of three functions: High-
Pass (capacitors), Low-Pass (inductors
or coils) and Bandpass (combination of
capacitor and coil).

Speaker Impedance
Freq.
Hertz
The most commonly used passive
crossover networks are 6dB/octave
systems. These are easy to construct
and require one component per filter.
Placing this filter in series with the
circuit will reduce power to the speaker
by 6dB/octave above or below the
crossover point depending on whether
it is a high-pass or low-pass filter. More
complex systems such as 12dB/octave
or 18dB/octave can cause impedance
problems if not professionally designed.

OPERATION
ADJUSTING GAIN
To adjust the gain setting, turn the amplifier gains all the way down. Turn the source unit volume up
until distortion is audible and then turn it down a bit until the distortion is inaudible. This will be
about two thirds all the way up on most source units. Next, turn the amplifier gain setting until once
again distortion is audible and then back it down until the distortion is inaudible. Rockford Fosgate
source units do not distort, so the volume can be used at maximum setting.
NOTE: For a more in depth setting procedure, contact Rockford Technical Support.
ADJUSTING CROSSOVER FREQUENCY
Placing the switch in the Full position sets the amplifier to the full range frequency mode, preventing
any crossover adjustment.
Placing the switch in the LP position allows the crossover frequency to be adjusted between
50-210Hz.
Turn the crossover adjustment knob all the way down. With the system playing, turn the crossover
adjustment knob up slowly until the desired crossover point is achieved.

TROUBLESHOOTING
NOTE: If you are having problems after installation follow the Troubleshooting procedures below.
Procedure 1: Check Amplifier for proper connections.
Verify that POWER light is on. If POWER light is on skip to Step 2, if not continue.
1. Check in-line fuse on battery positive cable. Replace if necessary.
2. Verify that Ground connection is connected to clean metal of the vehicle’s chassis.
Repair/replace if necessary.
3. Verify there is 10.5 - 15.5 Volts of current present at the positive battery and remote turn-on
cable. Verify quality connections for both cables at amplifier, stereo, and battery/fuseholder.
Repair/replace if necessary.
Procedure 2: Check Amplifier for audio output.
1. Verify good RCA/high-level input connections at stereo and amplifier. Check entire length of
cables for kinks, splices, etc. Test RCA/high-level inputs for AC current with stereo on.
Repair/replace if necessary.
2. Disconnect RCA/high-level input from amplifier. Connect RCA/high-level input from test stereo
directly to amplifier input.
Procedure 3: Check Amplifier if you experience Turn-on Pop.
1. Disconnect input signal to amplifier and turn amplifier on and off.
2. If the noise is eliminated, connect the REM lead of amplifier to source unit with a delay turn-on
module.
OR
1. Use a different 12 Volt source for REM lead of amplifier (i.e. battery direct).
2. If the noise is eliminated, use a relay to isolate the amplifier from noisy turn-on output.
Procedure 4: Check Amplifier if you experience excess Engine Noise.
1. Route all signal carrying wires (RCA, Speaker cables) away from power and ground wires.
OR
2. Bypass any and all electrical components between the stereo and the amplifier(s). Connect
stereo directly to input of amplifier. If noise goes away the unit being bypassed is the cause of
the noise.
OR
3. Remove existing ground wires for all electrical components. Reground wires to different
locations. Verify that grounding location is clean, shiny metal free of paint, rust etc.
OR
4. Add secondary ground cable from negative battery terminal to the chassis metal or engine block
of vehicle.
OR
5. Have alternator and battery load tested by your mechanic. Verify good working order of vehicle
electrical system including distributor, spark plugs, spark plug wires, voltage regulator etc.
