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.

4. Preamp-Level Input Connector - Connects to

5. Pre amp-Level AUX output Connector

line-level output from the source unit.

3. Speaker Output Connector - Connect speaker

wiring to these connectors. See wiring instruc-

tions on page 4 for more information.

2. Fuse - Three 30 Amp ATC type Fuses.

1. Power Connection for 12V+, GND and REM

connections for power wires. See wiring instruc-

tions on page 4 for more information.

6. Input-Level Control - Adjusts input sensitivity

7. This switch is select X-over slope

for pre-amp level and speaker level inputs.

10. The crossover frequency can be set at any frequency

11. (1) The HP frequency can be set at any frequency

(2) Bass Boost control will provide at frequency

Between 32Hz and 320Hz.

Between 20Hz and 100Hz.

Being set between 20Hz ~ 100Hz

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.

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.

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.
