About This Manual
To attain maximum amplifier perfor-
mance, we encourage you to read the
remaining pages before installing and
operating your new JBL Decade power
amplifier. Especially review the Appli-
cations section for ideas on designing
and expanding your system. Also, save
these instructions for future reference.
Important:Installation of automotive
stereo components can require extensive
experience in performing a variety of
electrical 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 partic-
ular 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 mon-
itor 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
product specifications. For best perfor-
mance, 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
drilling any holes or installing any
screws. Remember that mounting
screws can extend behind the mount-
ing 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
polarity markings on the rear panel.
Refer to the application drawings to set
up the amplifier for operation in stereo,
bridged-mono, bi-amp or tri-mode con-
figurations.
• 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 fac-
tory-installed audio systems for distor-
tion-free performance. All JBL Decade
Series power amplifiers feature built-in
electronic crossovers for easy system
expansion without additional outboard
processors.

source unit.
2.Floating Ground Factory-Head-Unit
Interface Speaker Input – Connects to
speaker level output from the source
unit (2-channel on DA4002, DA6502,
DA1002; 2 separate 2-channel connec-
tors on DA3504).
3.Speaker-Output Connector – 2-channel
on DA4002, DA6502 and DA1002; 4-
channel on DA3504.
4.Fuse – DA4002: 15A ATC,
DA6502: 20A 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 – Determines
whether the crossover is a High-Pass
