WARNING: Playing loud music 
in an automobile can hinder your 
ability to hear traffic and permanently 
damage your hearing. We recommend 
listening at low or moderate levels while
driving your car. JBL accepts no liability
for hearing loss, bodily injury or
property damage resulting from the use
or misuse of this product.

IMPORTANT: To get the best per-
formance from your JBL Power Series

®

amplifiers, we strongly recommend that
installation be entrusted to a qualified
professional. Although these instruc-
tions explain how to install JBL Power
Series amplifiers in a general sense,
they do not show specific installation
methods that may be required for your
particular vehicle. 
If you do not have the necessary tools
or experience, do not attempt the instal-
lation yourself. Instead, please ask your
authorized JBL car audio dealer about
professional installation.

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 (–) negative lead from
your vehicle’s 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 electri-
cal wiring. Use extreme caution when
cutting or drilling in and around these
areas.

• 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 cer-

tain they are secure and properly
insulated.

• If the amplifier’s fuse must be

replaced, use only the same type and
rating as that of the original. Do not
substitute another kind.

CHOOSING A LOCATION
AND MOUNTING THE
AMPLIFIER
Amplifiers need air to stay cool. Suitable
locations are under a seat (provided the
amplifier doesn’t 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 backseat 
passengers or shifting cargo in the
trunk. Mount the amplifier so that it
remains dry – 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.

POWER CONNECTIONS
The Power Series amplifiers are 
capable of delivering extremely high
power levels, and require a heavy-duty
and reliable connection to the vehicle’s
electrical system in order to perform
optimally. Please adhere to the 
following instructions carefully:

Ground Connection
Connect the amplifier’s Ground (GND)
terminal to a solid point on the 
vehicle’s metal chassis, as close to 
the amplifier as possible. Refer to the
chart below to determine minimum
wire-gauge size. Scrape away any paint
from this location; use a star-type lock
washer to secure the connection.

Power Connection
Connect a wire (see chart at right for
appropriate gauge) directly to the 
vehicle’s positive battery terminal, 
and install an appropriate fuse holder
within 18" of the battery terminal. Do not
install the fuse at this time. Route the
wire to the amplifier’s location, and
connect it to the amplifier’s Positive
(BATT +) terminal. Be sure to use
appropriate grommets whenever
routing wires through the firewall or
other sheet metal. Failure to adequately
protect the positive wire from potential
damage may result in a vehicle fire.
When you are done routing and
connecting this wire, you may install the
fuse at the battery.

NOTE: The BPx2200.1 is supplied with
an external 150A fuse. If you are running
a dedicated wire to this amplifier, this
fuse should be installed near the
battery, as specified above. If you are
running multiple amplifiers off a power
distribution block, this fuse should be
installed between the distribution block
and the BPx2200.1. 
In any case, a fuse must be installed
within 18" of the battery terminal.

Remote Connection
Connect the amplifier’s Remote (REM)
terminal to the source unit’s Remote
Turn-On lead using a minimum of 
18-gauge wire.

Speaker Connections
Refer to the application guides on 
the pages that follow. Speaker 
connections should be made using 
a minimum of 1.5 mm

2

These recommendations assume 
2,3 to 3,5 m wire runs. If your installation
differs markedly, you will need to adjust
the wire gauge accordingly.

Important Note: If you are planning to
use optional neon tubes, you must
install them before making any
electrical connections to the amplifier
(refer to “Installing Neon Tubes” on
page 7).
