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.

Test Conditions and Notes
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-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.

BP-300.1 Features
1 Channel Automotive Amplifier

Controls and Connections
Controls and Connections
Mounting the Amplifier
1. It allows left and right input channels to be
connected to be amplifier using RCA plugs.
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 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 signals to be the amplifier.

Service Bulletin
Service Bulletin JBL2000-04 - November 2000 Warranty labor rate: MINOR
To: All JBL Service Centers
Models: BP300.1, BP600.1, BP1200.1
Subject: Muting during intense bass passages
The JBL BP series amplifier is designed with the following protection circuits:
Thermal (excess heat)
DC voltage on the output terminals (overdriving or “clipping”)
Short Circuit (excessive current)
Under certain large signal conditions during intense bass passages, the unit will go into protection. These
amplifiers are behaving as designed. As the unit is driven into hard clipping, the protection circuit found in BP
Series amps was engineered to protect your loudspeakers from being destroyed by a severely clipped output
signal. This can be remedied easily by turning the volume down somewhat on your music source.
In the event you receive a BP series amplifier with the complaint: “Under a large signal input, with
music that is composed of high-level bass, the amplifier mutes for 2-3 seconds, and then returns to
normal operation”, the following modification will effectively increase the amount of clipping that is allowed
to occur before the protection circuit engages by increasing the threshold at which the amplifier mutes - for
the benefit of customers who use the amps in SPL competition, or for customers who insist on driving the
amplifiers into this potentially hazardous zone.
1) Turn the amplifier upside-down and remove the Phillips screws holding the bottom cover on.
2) Locate and change R510 from 47K to 4.7K ohms 1/5W (JBL part# RE212047200).
3) Locate and change R511 from 22K to 2.2K ohms 1/4W (JBL part# QAF0450-222).
4) If it is not already present, add new part - 4.7uf 50v electrolytic capacitor (JLB part# EC070114760) in
parallel with R511. Polarity: The negative side of the capacitor must be connected to the junction of
R510/R511, which can be discovered with an ohmmeter.
NOTE: Using the correct soldering techniques, you should be able to make these changes from the top of the
PCB without its removal.
5) Replace bottom cover; test amplifier
