							¥ Before drilling or cutting holes, use a
utility knife to remove unwanted fabric
or vinyl to keep material from snagging
in a drill bit.
¥ When routing cables, keep input-signal
cables away from power cables and
speaker wires. 
¥ When making connections, make 
certain they are secure and properly
insulated.
¥ If the amplifierÕs fuse must be replaced,
use only the same type and rating as
that of the original. Do not substitute
another kind.
2
Installation Warnings  and Tips¥  Always wear protective eyewear when
using tools.
¥ Turn off all audio systems and other
electrical devices before you start.
Disconnect the (Ð) negative lead from
your vehicleÕs battery.
¥ Check clearances on both sides of a
planned mounting surface before
drilling any holes or installing any
screws. Remember that the screws can
extend behind the surface.
¥ At the installation sites, locate and
make a note of all fuel lines, hydraulic
brake lines, vacuum lines and electrical
wiring. Use extreme caution when 
cutting or drilling in and around these
areas.
Thank youfor purchasing a JBL Power
Seriesª amplifier. In order that we may
better serve you should you require 
warranty service for your new amplifier,
please retain your original purchase
receipt and return the enclosed warranty
registration card.
Warning:Playing loud music in an auto-
mobile can permanently damage your
hearing as well as hinder your ability to
hear traffic. We recommend listening at
low levels while driving your car. JBLaccepts no liability for hearing loss, bodilyinjury or property damage resulting from
use or misuse of this product. 
Important:Installation of automotive
stereo components can require extensive
experience in performing a variety of
mechanical and electrical procedures.
Although these instructions explain, in a
general sense, how to install Power
Series amplifiers, they may not show 
the exact installation methods for your
particular vehicle. If you feel you lack the
necessary tools or experience, ask your
authorized JBL car-audio dealer about
professional installation options.
Choosing a Location and
Mounting the AmplifierAmplifiers need air to stay cool. Suitable
locations are under a seat (provided the
amplifier doesnÕt interfere with the seat
adjustment mechanism), in the trunk or
in any other location which provides
enough air for the amp to cool itself. Do
not mount the amplifier with the heat
sink facing downward, as this makes
convection cooling of the amplifier
impossible.
Mount the amplifier so that it is not
damaged by the feet of back-seat pas-
sengers or shifting cargo in the trunk.
Mount the amplifier so that it remains
dry Ð never mount an amplifier outside
the car or in the engine compartment. 
Using the amplifier as a template, mark
the location of the mounting holes on
the mounting surface, drill pilot holes,
and attach the amplifier to the mounting
surface with  screws. Make sure the
amplifier is mounted securely.

Wiring the Power ConnectionsRefer to Figures 1Ð3 for connector loca-
tions. All the Power Series amplifiers
will accept up to 4-gauge power and
ground wire.
For power, remote and ground connec-
tions, strip off one end of each jacket to
reveal bare wire for insertion into the
connectors. Connect a wire from the
GND connector on the amplifier to the
nearest bare-metal chassis component;
scrape away the paint to ensure good
conductivity. Next, connect a wire
between the BATT terminal on the
amplifier and the POS(+) terminal of the
vehicleÕs battery. Pass the wire through a
factory-installed grommet in the firewall,
or install a grommet if a factory grom-
met is not available. Connect a wire
between the REM terminal of the ampli-
fier and the Òremote outÓ or power-
antenna lead on the vehicleÕs radio. 
Wiring the Speaker-Output
ConnectionsP80.2, P180.2, P80.4
All the Power Series amplifiers will
accept up to 8-gauge speaker wire.
Connect the speakers, observing proper
polarity, to the speaker-output connector.
The total impedance of the speaker 
system connected to the amplifier when
the amplifier is driven in stereo must be
at least two ohms. 
If you are bridging the amplifier, connect
the speaker wires to the terminals
marked Òbridged,Ó observing proper
polarity. The total impedance of the
speaker system connected to the amplifi-
er must be at least four ohms in bridged
mode. 
If you are running the amp in Tri-Mode
(stereo and mono simultaneously), con-
nect the satellite speakers to the speaker
connector as you would a pair of stereo
speakers. Connect the subwoofer to the
terminals marked ÒbridgedÓ Refer to the
chart above to determine the capacitor
and inductor values youÕll need to route
bass signals to the woofer, and the
midrange and high frequencies to the
satellite speakers. These passive
crossover components will also ensure
that the impedance of the speaker sys-
tem doesnÕt drop below two ohms.
BP150.1, BP300.1, BP600.1, BP1200.1
Connect the woofers to the amplifier,
observing proper polarity. Although
these amplifiers have a single channel,
duplicate positive and negative connec-
tors are provided to facilitate the connec-
tion of multiple woofers.
The total impedance of the speaker 
system connected to a BP Series 
amplifier must be at least 1 ohm.

Setting Input Level Initially, turn the input-sensitivity LEVEL
control to its maximum (counter-clock-
wise) position. Turn on the source unit
and increase the volume control until it
is approximately three-quarters of maxi-
mum-output level. Slowly increase the
input LEVEL control (clockwise) while lis-
tening to the quality of the reproduced
sound. When you hear distortion on the
music peaks, turn the LEVEL control
back slightly. This is the maximum 
undistorted output level of your system.
Turning the LEVEL control up farther
WILL NOT INCREASE THE OUTPUT
POWER OF YOUR AMPLIFIER! It will
only decrease the amount of volume-
control rotation before the amp is at full-
output power. It will also increase the
amount of extraneous noise present in
your system.
Wiring the Input-Signal
ConnectionsConnect a pair of signal cables with
RCA-type ends between the connectors
on the amplifier and the RCA-type signal
connectors on the source unit. If your
radio has only speaker-level outputs, you
should connect them to the speaker-level
input connectors, observing proper
polarity. When using the speaker-level
inputs, it is not necessary to connect a
wire between the ÒremoteÓ terminal of
the amplifier and the ÒremoteÓ lead from
the source unit. The speaker-level inputs
will sense voltage on the speaker 
outputs and turn the amplifier on 
automatically.
If you are installing a P80.4 amplifier and
your source unit has only one pair of
RCA-type output connectors and a pair
of speaker-level outputs, you may 
connect the RCA outputs to a pair of
amplifier input channels (front or rear),
and the speaker-level outputs to the
other pair of amplifier input channels.
System Setup and AdjustmentRefer to figures 1Ð6 for location of
adjustment switches and controls.
Electronic Crossover and Bass Boost
P80.1, P80.4, P180.2
The electronic crossover can be selected
as a 12dB/oct. high-pass filter (HPF)
12dB/oct. low-pass filter (LPF) or it 
can be defeated (FLAT). The crossover
frequency can be set at any frequency
between 32Hz and 320Hz.
BP150.1, BP300.1, BP600.1, BP1200.1
These amplifiers are designed to 
drive subwoofers. Consequently, the 
electronic crossover is a 12dB/oct. 
low-pass filter which can be set at any
frequency between 32Hz and 320Hz.
The bass boost control will provide up
to 6dB of boost at 50Hz.
The BP150.1, BP300.1, BP600.1 and 
BP1200.1 are designed to provide con-
stant bass regardless of the position of
the source unitÕs front-to-rear fader posi-
tion. Use of this feature requires that all
four inputs are connected to the source
unit as labeled on the amplifier (front,
rear, right and left). If your source unit
has only one pair of RCA-type output
connectors and a pair of speaker-level
outputs, you may connect the RCA out-
puts to a pair of amplifier input channels
(front or rear), and the speaker level out-
puts to the other pair of amplifier input
channels. If nonfading bass is not impor-
tant in your system, connect a pair of
inputs, either speaker-level or RCA-type,
to either the front or rear input connec-
tors on the amplifier.
