Signal Source
Unless otherwise specified, all tests shall be conducted with the Audio Signal Generator output configured to
be balanced, less than or equal to 50 ohm source impedance, and floating. The signal source "GND" shall be
connected to the Amplifier PWR GND at the Amplifier.

Output Load
Unless otherwise specified, all tests shall be conducted with 4 ohm resistive loads having less than 10%
reactive components at any frequency below 350KHz. Each resistor shall have a value that remains within 1%
while dissipating the rated output of the unit under test.

Controls and Connections
Controls and Connections
Mounting the Amplifier
1. It allows left and right input channels to be
connected to the amplifier using RC plugs.
3. Fuse - One 20 Amp ATC type Fuse.
2. Speaker Output Connector - Connect speaker
wiring to these connectors. See wiring instruc-
tions on page 4 for more information.
The JBL BP Series amplifiers can be mounted in virtually any location inside the vehicle.
However, make sure to keep the amplifier away from heater vents or ducts.
However, make sure to keep the amplifier away from heater vents or ducts.
1. At the chosen site, use the amplifier as a mounting template and mark the locations of the
four mounting holes.
four mounting holes.
2. Drill a small pilot hole at each marked location.
3. Mount the amplifier and securely tighten the mounting screws.
4. Power Connection for 12V+, GND and REM
connections for power wires. See wiring instruc-
tions on page 4 for more information.
5. Input-Level Control - Adjusts input sensitivity
for pre-amp level and speaker level inputs.
6. The electronic crossover is a 12dB/oct.
Low pass filter which can be Set at any frequency
between 32Hz and 320Hz.
7. The bass boost control will provide up to 6dB of boost
at 50Hz.
8. It allows left and right input channels such as high
level speaker output signal to be the amplifier.
