JBL continually strives to improve its products.  New materials, production methods and design refinements are 
introduced into existing models without notice as a routine expression of our design philosophy.  For this reason,
Power Series Multichannel Automotive Amplifiers may differ in some respects from their published specifications 
and descriptions, but will always equal or exceed the original specifications unless otherwise stated.

Test Conditions and Notes
2-Channel Operation
Advanced MOSFET Oversized Floating Rail Power Supply 
Floating Ground Factory - Head - Unit Speaker - Level input
Variable Input Sensitivity (250mV - 4V)
Fully Complementary Output Stage with Class-A Voltage Amplification
Gold-plated Power, Input and Output Connectors
2-Ohm Stable (Stereo)
All tests to be done, unless otherwise specified, from 20Hz to 40KHz at 14.4V DC into 4 ohm loads and adjust 
the units gain so that with a .775 volt input signal the unit is at its maximum rated output. All measurements 
will be done using an Audio precision system one and the supply voltage.
An A+ line voltage of 14.4V DC shall be applied to the unit under test for all measurements unless otherwise 
specified. The voltage applied to the unit shall be measured at the power connection on the Amplifier.
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 75KHz. Each resistor shall have a value that remains within 1% 
while dissipating the rated output of the unit under test.
Power Indicator LED steadily illuminates for normal operation. LED blinks when
protection circuitry is engaged, and during power up.

Controls and Connections
Controls and Connections
Mounting the Amplifier
1. Preamp-Level Input Connector - Connects to 
    line-level output from the source unit.
 
    
2. Speaker Output Connector - Connect speaker
    wiring to these connectors. See wiring instruc-
    tions on page 4 for more information.
3. Fuse - Two 20 Amp ATC type Fuses.
 
    
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.
1. At the chosen site, use the amplifier as a mounting template and mark the locations of the 
    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 crossover frequency 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.This functions L&R channel output in speaker by
   connecting L&R channel input when input mode can
   be set on "ST"
   if setting on "Mono", this functions L&R channel output
   in speaker only by connecting R channel pass. 
9. This switch allows these two amplifier channels to play
    full range,low pass,or high pass
