1. Connect the speakers, observing

proper polarity, to the speaker output
barrier strip on the amplifier using at
least 1,25mm

2

high-quality speaker

wire. (Note: The total impedance of the
speakers connected to the outputs
when the amp is driven in stereo must
be at least 2 ohms.) 

2. If you are bridging the amplifier, conne-

ct the speaker wires to the terminals
marked “bridge”, observing proper
polarity. (Note: The total impedance of
the speaker system to be connected to
the amplifier must be at least 4 ohms in
bridge mode.)

3. If you are running the amp in Tri-Mode

(stereo and mono simultaneously to
one or two pairs of satellite speakers
and a subwoofer), refer to the chart
below to determine the capacitor and
inductor values you’ll need to route
bass signals to the woofer, and midran-
ge and high frequencies to the satellite
speakers. These passive crossover
components will also ensure that the
impedance of the speaker
system doesn’t drop below 2 ohms.

1. If you are using conventional RCA input

connections and a source unit with out-
put voltage less than 4V, simply plug
the RCA plugs into the RCA jacks on
the amplifier.

2. If you are connecting the amplifier to a

factory-installed source unit, or to a
source unit that only has speaker-level
outputs, connect the speaker outputs of
the source to the speaker input plug on
the amp using the connector provided.
Observe the following color-codes: 

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.

Refer to diagrams on page 3 for connect-
or locations. 
1. For power, remote and speaker wires,

strip 1⁄4" off one end of each jacket to
reveal bare wire for insertion into the
barrier strip connectors.

2. Locate the 3-connection barrier strip

labeled +Batt, Rem and Gnd. Connect a
black wire (at least 2mm

for DA4002,

2,5mm

2

for DA6502, DA1002 and

DA3504) to the Gnd terminal and con-
nect the other end to the nearest bare-
metal chassis component. Then, conne-
ct a red wire (at least 2mm

2

for DA4002,

2,5mm

2

for DA6502, DA1002 and

DA3504) from the vehicle’s +12-volt
battery terminal to the +Batt terminal
on the barrier strip. Finally connect a
blue wire 1,25mm

2

to the Rem terminal

on the barrier strip and connect the
other end to the Rem output of the
source unit.
