About This Manual
To attain maximum amplifier performan-
ce, we encourage you to read the remai-
ning pages before installing and operat-
ing your new JBL Decade power amplifi-
er. Especially review the Applications
section for ideas on designing and expan-
ding your system. Also, save these instru-
ctions for future reference.
Important: Installation of automotive ste-
reo components can require extensive
experience in performing a variety of ele-
ctrical and mechanical procedures.
Although these instructions explain how
to install a JBL Decade power amplifier in
a general sense, they do not show the
exact installation methods for your parti-
cular vehicle. If you do not have the expe-
rience, do not attempt the installation
yourself; instead ask your Authorized JBL
Car-Audio Dealer about professional
installation options.
Installation Precautions and Notes
• The JBL Decade power amplifiers have
five levels of circuit protection that moni-
tor the amplifier and will shut it down if
the electrical system voltage drops
below 5Vdc or exceeds 18Vdc, tempera-
tures are above 194° F (90° C), short cir-
cuits occur or current draw exceeds pro-
duct specifications. For best performance,
check the intended mounting site to make
sure the operating environment does not
create conditions that will trigger circuit
protection.
• Prior to installation, turn off all audio
systems and other electrical devices.
Also disconnect the (–) negative lead
from the vehicle’s battery.
• At the installation site, locate and make
a note of all fuel lines, hydraulic brake
lines and electrical wiring. Use extreme
caution when cutting or drilling in and
around these areas.
• Check clearances on both sides of a
planned mounting surface before dril-
ling any holes or installing any screws.
Remember that mounting screws can
extend behind the mounting surface. 
• Always wear protective eyewear when
using tools. 
• When routing cables, keep input signal
cables away from power cables and
speaker wires. 
• When making connections, make sure
that each connection is clean, insulated,
and properly secured. Observe the pola-
rity markings on the rear panel. Refer to
the application drawings to set up the
amplifier for operation in stereo, bri-
dged-mono, bi-amp or tri-mode confi-
gurations.
• If the amplifier’s fuse must be replaced,
use only the same rating and type as a
replacement. Do not substitute another
kind.
Thank you
for purchasing your new
JBL Decade
Series power amplifier.
Decade Series power amplifiers feature
the latest advances in discrete circuit
topology ensuring low distortion and
superbly clean and clear sound quality.
In addition to RCA-type pre-amp inputs,
Decade Series amplifiers feature Floating
Ground Factory-Head-Unit Interface
,
designed to facilitate integration with fact-
ory-installed audio systems for distortion-
free performance. All JBL Decade Series
power amplifiers feature built-in electro-
nic crossovers for easy system expansion
without additional outboard processors.

2 separate 2-channel connectors on
DA3504).
3. Speaker-Output Connector – 2-channel
on DA4002, DA6502 and DA1002; 
4-channel on DA3504.
4. Fuse – DA4002: 20A ATC, 
DA6502: 25A ATC, DA1002 2x 20A ATC,
DA3504: 30A ATC.
5. Power Connector – Connection for
12V+, Gnd and Rem in. 
6. Input-Mode Switch – Sums left and
right inputs.
7. Input-Level Control – Adjusts input sen-
sitivity for pre-amp level and speaker
level inputs.
8. Crossover Selector – DA4002, DA6502,
DA3504: Determines whether the cros-
sover is a High-Pass filter @120Hz (HP),
a Low-Pass filter @80Hz (LP) or unfilte-
red (FLAT). DA1002: Low-Pass frequen-
cy selector (70Hz or 100Hz).
9. Bass E.Q. – Enables bass boost +6dB 
@ 50Hz.

Wiring the Speaker Output
Connections
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.
Wiring the Input Connections
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: 
Mounting the Amplifier
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.
Wiring the power Connections
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
2
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.
