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,
DECADE  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
Simultaneous Stereo +Mono 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)
Power-on Indicator Badge
Fill Programmable 12dB per Octave Crossover (Low-pass,High-pass,Thru pass)
All tests to be done, unless otherwise specified, from 20KHz to 20KHz 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(on amp chassis top)-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 the source unit
2. Speaker-Level Input Connector - Use this
    connector for speaker level input signals.
    A wire harness is supplied use with this
    connector. See"Typical System Configuration"
    Section (page4)for wiring instructions
3. Speaker Output Connector - Connect speaker
    wiring to these connectors. See wiring instruc-
    tions on page 4 for more information.
4. Fuse - 15 Amp attached type Fuses.
The JBL Decade 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.
5. Power Connection for 12v+,GND and REM
    connections for power wires. See wiring 
    instructions on page 4 for more information.
6. Input-Level Control - Adjusts input sensitivity
   for pre-amp level and speaker level inputs.
8. Bass E.Q. - This switch activates a built-in Bass
    Boost circuit used to increase low-bass output
    on the selected speaker output group. Enables
    bass boost [email protected]

7. Crossover Selector - Determines wheth the
    crossover is a High-pass filter @120HZ(HP),a
    Low-pass filter,@120Hz(LP) or unfiltered (FLAT)
