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, BP Series
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.

BP-150.1
1 Channel Automotive Amplifier
Features
1-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-D Voltage Amplification
Gold-plated Power, Input and Output Connectors
1-Ohm Stable
Test Conditions and Notes
All tests to be done, unless otherwise specified, from 10Hz to 320Hz 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 i's maximum rated output. All measurements
will be done using an Audio precision system one and the supply voltage.
An B+ 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 350KHz. Each resistor shall have a value that remains within 1%
while dissipating the rated output of the unit under test.
Power Indicator Green LED steadily illuminates for normal operation. Illuminates up Red LED blinks when
protection circuitry is engaged, and during power up.

1. It allows left and right input channels to be
connected to the amplifier using RC plugs.
2. Speaker Output Connector - Connect speaker
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.
wiring to these connectors. See wiring instruc tions on page 4 for more information.
6. The electronic crossover is a 12dB/oct.
Low pass filter which can be Set at any frequency
between 32Hz and 320Hz.
3. Fuse - One 20 Amp ATC type Fuse.
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.
Mounting the Amplifier
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.
