INSTALLING THE REMOTE  
CONNECTING THE SUBWOOFER  
LEVEL CONTROL TO BASSPROII  
The Subwoofer Level Control may be  
mounted under the dash or dismantled  
and mounted in the dash for a factory-  
installed appearance.  
Choose a mounting location that  
Route the cable behind the dash or  
BassProII Connection Panel  
allows easy access to the control,  
and provides 1-3/4" clearance behind  
the mounting surface. Drill a 9/32"  
hole in the mounting surface. Feed  
the Subwoofer Level Control’s  
other interior panels and under the  
carpet. Do not route the cable outside  
the vehicle. Connect the RJ11 cable  
between the RJ11 receptacle on the  
BassProII and the receptacle on the  
Subwoofer Level Control (Figure 6).  
UNDER-DASH MOUNTING  
Select a mounting location that allows  
easy access to the control while driv-  
ing. Using the Subwoofer Level Control  
as a template, mark and drill holes in  
the mounting surface. Attach the  
potentiometer shaft (with the knob  
removed) through the hole and use the  
nut and washer provided to hold the  
control in place (Figure 5).  
Subwoofer Level Control using the  
mounting screws provided (Figure 4).  
IN-DASH MOUNTING  
Disassemble the Subwoofer Level  
Control by removing the two Phillips-  
head screws on the front panel,  
rear panel and on top. Remove the  
Subwoofer Level Control’s bottom and  
side panels. Slide the Subwoofer Level  
Control’s PC board forward to release  
the RJ11 connector from the back  
panel and remove the board along with  
the potentiometer, knob and connector  
as a single assembly.

POWER CONNECTIONS  
Connecting power to BassProII is  
shown in Figure 7. Please observe  
the following installation tips:  
Use at least #12 AWG wire for the  
Positive Battery (BATT +12) and Ground  
) connections. If needed, use at  
least #20 AWG wire for the remote  
(REM) turn-on connection.  
Route all power wires through a grom-  
met in the vehicle’s firewall. If a factory  
grommet is not available, install one.  
Connect a short ground wire from  
BassProII’s ground terminal ( ) to the  
nearest bare metal surface. For a good  
connection, use sandpaper to clear  
paint from the metal surface and use  
a screw with a lock (star) washer.  
The remote (REM) connection requires  
a +5 to +12 Vdc signal for BassProII  
to turn on when using the line-level  
connections. Most head units with  
preamp outputs provide this remote  
voltage signal. As an alternative,  
connect this terminal to a switched  
ignition circuit.  
(
When using the high-level input con-  
nections, BassProII will automatically  
turn on when you turn on your radio.  
In this case, the remote (REM) con-  
nection is not needed. Use at least #20  
AWG speaker wire for speaker-level  
input connections.  
Connect BassProII’s “BATT +12V”  
terminal directly to the battery’s posi-  
tive (+) terminal. Install a fuse holder,  
with a 20A fuse, within 18" of the bat-  
tery’s positive (+) terminal.

CONTROLS AND FUNCTIONS  
BassProII has controls and indicators  
that help simplify sonic integration with  
almost any vehicle’s unique acoustic  
properties. These controls are located  
on the amplifier panel, as shown in  
Figure 10.  
POWER LED: This indicator  
will glow red when the BassProII  
is operating.  
AUTO TURN-ON: For speaker-  
level connections, used this switch to  
activate (or deactivate) BassProII’s  
automatic turn-on circuit. For most  
speaker-level applications, slide the  
switch to the AUTO position. If you  
prefer to use the remote (REM)  
connection, slide the switch to the  
OFF position.  
3. Turn the head unit ON and play a  
selection of your favorite music  
track that has substantial bass.  
4. Adjust the CROSSOVER control  
counterclockwise, until you hear  
only low-frequency information.  
Example – you should not hear  
vocals coming from BassProII  
when seated in the normal listening  
position.  
5. Adjust the BASS CONTROL either  
clockwise or counterclockwise to  
suit your taste, and to avoid audible  
distortion.  
GAIN CONTROL: Use this  
control to adjust the relative volume  
(loudness) of BassProII with the other  
speakers in the vehicle.

CROSSOVER: Use this control  
to adjust the amount of high-frequency  
information present in BassProII’s out-  
put. A lower value signifies less high-  
frequency content.  
REMOTE BASS  
CONTROL: Use this RJ-11 jack  
to connect the supplied remote bass  
control.  
6. If you elect not to install the Remote  
Bass Control, adjust the GAIN  
control to the maximum level that  
provides undistorted output from  
the BassProII, with the head unit’s  
volume control at its 3 o’clock  
setting.  
SETTING THE CONTROLS:  
1. Make sure the head unit is off and  
VOLUME control is set to minimum.  
2. On BassProII’s amplifier panel, set  
the CROSSOVER to its maximum  
frequency of 120Hz, as shown in  
Figure 10.  
NOTE: In most cases the above steps  
will provide you with satisfactory

CONTROL, set GAIN to maximum  
and set the BASS CONTROL to the  
midpoint.  
results. However, the actual process  
may require several readjustments of  
each control, since the settings will  
interact with one another. If necessary,  
consult your authorized JBL car audio  
dealer for help in tuning your system.

TROUBLESHOOTING  
PROBLEM  
CAUSES AND SOLUTIONS  
POWER LED is not lit.  
1. Fuse is blown and needs  
replacement.  
2. Head unit not functioning properly.  
3. Check remote turn-on, power and  
ground connections.  
POWER LED is lit but there is no bass.  
Output sounds muddy or distorted.  
1. Inputs are not connected. Check  
connections.  
2. Head-unit fader controls are not set  
properly. Adjust head-unit controls to  
feed audio signals to BassProII.  
3. Incorrect GAIN control setting.  
1. GAIN is set too high.  
2. Bass level is set too high on  
head unit.  
3. Head unit output is distorted or  
blown. See your authorized JBL car  
audio dealer.  
Output gets louder when the head-unit  
balance is adjusted to L or R.  
Using speaker-level connection: one of  
the speaker connections is reversed  
(+/–). Reverse one channel.  
POWER LED remains ON after system  
is turned off.  
Speaker-level connections have a five-  
minute turn-off delay. Check the unit at  
a later time.
