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 - 6V)
Fully Complementary Output Stage with Class-D Voltage Amplification
Gold-plated Power, Input and Output Connectors
1-Ohm Stable ( 2 ohm parallel )
All tests to be done, unless otherwise specified, from 20Hz to 320Hz at 14.4V DC into 2 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 2 ohm resistive loads having less than 10%
reactive components at any frequency below 350Hz. 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
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.

8. This switch is set to 2-channel mode(2CH/BR) to drive
a pair of subwoofers or bridge(mono) mode to drive a
single subwoofer(PARALLEL).
It's allowed to use parallel mode when the nominal
impedance of the speaker system is 2 ohm or greater

APPLICATIONS – BPx MODELS
To the right are several application
diagrams to help plan your subwoofer
system installation. Figures 1 through 3
show how to configure the JBL Power
Series subwoofer amplifiers (models
BPx500.1, BPx1100.1 and BPx2200.1)
for 2-channel, bridged-mono and
parallel-mono operation
“Setting the Output Mode” on page 6).
NOTE: For simplicity, Figures 1 through
3 do not show power, remote and input
connections.
NOTE: If the nominal impedance
of your speaker system is close to
2 ohms, be prepared to try both
bridged and parallel configurations to
determine which performs better.

Figure 1. The JBL Power Series
subwoofer amplifier is set to
2-channel mode to drive a pair
of subwoofers.
Figure 2. The JBL Power Series
subwoofer amplifier is set to
bridged (mono) mode to drive
a single subwoofer. Use this
mode only when the nominal
impedance of the speaker
system is 2 ohms or greater.
Figure 3. The JBL Power Series
subwoofer amplifier is set to
parallel mode to drive a single
subwoofer. Use this mode only
when the nominal impedance
of the speaker system is less
than 2 ohms.
NOTE: A jumper is added
between the + terminals.
