Amplied Subwoofer Systems with DCD™ Amplier Technology
Thank you for purchasing a JL Audio amplified subwoofer system for
your automotive sound system.
Your subwoofer system has been designed and manufactured to exacting
standards to provide high-quality sub-bass performance and years of
musical enjoyment in your vehicle. For maximum performance, we
highly recommend that you have your new subwoofer system installed
by an authorized JL Audio retailer. Your authorized retailer has the
necessary training, expertise and installation equipment to ensure
optimum performance from this product. Should you decide to install
your subwoofer system yourself, please take the time to read this manual
thoroughly so as to familiarize yourself with it installation requirements
and setup procedures.
If you have any questions regarding the instructions in this
manual or any aspect of your subwoofer system’s operation, please contact
your authorized JL Audio retailer for assistance. If you need further
assistance, please call the JL Audio Technical Support Department at
(954) 443-1100 during business hours.
SAFETY CONSIDERATIONS
• Install this subwoofer system in a dry, wellventilated location that does not interfere
with your vehicle’s safety equipment (air bags,
seat belt systems, ABS brake systems, etc.).
• Securely mount the subwoofer system so
that it does not come loose in the event of
a collision or a sudden jolt to the vehicle.
• Check before drilling to make sure that you
will not be drilling into a gas tank, brake line,
wiring harness or other vital vehicle system.
• Do not run system wiring outside or
underneath the vehicle. This is an
extremely dangerous practice, which
can result in severe damage/injur y.
• Protect all system wires from sharp edges by
carefully routing them, tying them down and
using grommets and loom where appropriate.
• Secure all wiring as needed, using cable
ties or wire clamps to protect them
from moving parts and sharp edges.

PRODUCT DESCRIPTION
Enclosed subwoofer system with builtin DCD™ Class D amplifier and specially
engineered, low-impedance driver(s).
ABOUT DCD™ TECHNOLOGY
JL Audio’s exclusive DCD™ amplifier technology
combines direct power conversion with an ultrahigh current output section and unique lowimpedance drivers to extract maximum power and
efficiency. By directly converting a vehicle’s 12V
supply into speaker power, DCD™ amplifiers are
free of traditional switching power supplies, thus
enabling them to be very compact, while generating
remarkable power output with unprecedented
efficiency (up to 94%). This also permits DCD™
amplifiers to operate at much cooler temperatures
than conventional amplifiers.
WARNING! DCD™ amplified subwoofer
systems use very specific components. Never
use a DCD™ amplifier or its companion
subwoofer(s) with incompatible, non-DCD™
products. Doing so will void the warranty
and may cause severe damage/injury.
INSTALLATION APPLICATIONS
The built-in amplifier used in this subwoofer
system is designed for operation in vehicles
with 12V, negative-ground electrical systems.
Using this product in systems with positive
ground and/or voltages other than 12V
may result in damage to the product and
will void the warranty. This product is not
certified or approved for use in aircraft.
INSTALLATION PROCEDURE/CONNECTIONS
All connections are located on the amplifier
panel of the enclosure. All connections are made
via RCA-ty pe or quick-disconnect plugs, making it
easy to remove the enclosure quick ly, anytime you
need additional space in your vehicle.
1. Disconnect the NEGATIVE battery post
connection and secure the disconnected
cable to prevent accidental reconnection
during insta llation. This is an essential
safety precaution during installation!
2. Run power wire from the battery location to
the amplifier’s “+12 VDC” connection, taking
care to route it in such a way that it will not be
damaged and will not interfere with vehicle
operation. 8 AWG is the recommended
power wire size for this amplifier.
3. An appropriate fuse at the main power
wire to the amplifier is vital for vehicle
safety. This fuse must be installed within 18
inches (45 cm) of the positive (+12V) batter y
post connection. If this is the only device
connected to this main wire, use a 30A fuse.
Do not install the fuse until the power wire
has been securely connected to the amplifier.
4. Find a good, solid meta l grounding point
close to the amplifier panel and connect the
negative power wire to it using appropriate
hardware. Use the same sized wire used
for the +12V connection, no longer than 36
inches (90 cm) from the amplifier’s ground
(GND) connector to the ground connection
point. 8 AWG is the recommended
ground wire size for this amplifier.
5. Run a wire from the source unit’s positive
(+12V) remote turn-on output to the
amplifier’s “Remote” connection. If your
source unit does not have a dedicated remote
turn-on output, you may elect to use one of
the automatic turn-on options, configured via
the amplifier’s “Turn-On Mode” switch. (See
“Control Panel Settings and Adjustments.”)
6. Signal Input (Low-Level): Connect the
amplifier’s RCA input jacks to the source
unit’s preamp level output jacks. You may
run a stereo or a mono signal into the
2 JL AUDIO
®
inputs of the amplifier. The amplifier’s

input section automatically sums stereo
signals to mono for the internal amplifier
section. When feeding a single, low-level
RCA input connection, use a Y-adaptor
splitter to split the mono signal and connect
it to both Left and Right RCA inputs.
7. Signal Input (High-Level): If your system
does not offer a preamp level signal option,
you can connect speaker level signals directly
to the “High-Level Inputs” connector using
the supplied 4-pin plug and wire harness.
Simply splice the appropriate left/right
and positive/negative wires to the included
harness, and plug the harness into the “HighLevel Inputs” connector on the amplifier. The
amplifier will attenuate the high-level signal
to make it compatible with its input stage.
Refer to the table below for corresponding
wire color information. Make sure to observe
correct polarity in making high-level input
connections. Failure to do so will result
in a loss of signal (poor performance).
8. Make necessary adjustments to the
input sensitivity and filter controls.
9. With the optional RBC-1 Remote Level
Control (sold separately), you can control
the amplifier’s output level from the
front of the vehicle. Connect the RBC-1
to the amplifier’s panel-mounted RJ11
input jack. (Refer to Appendix B)
POWER CONNECTIONS PLUG
To connect the power wires and remote
turn-on wire to the amplifier, unplug the
“Power Connections” plug from the amplifier
panel (pull back firmly) and back out the set
screws on the connector plug using a Phillips
head screwdriver. Strip 3/8 inch (10 mm) of
insulation from the end of each wire and insert
the bare wire into the receptacle on the power
connector plug, seating it firmly so that no
bare wire is exposed. While holding each wire
in place, tighten each set screw firmly, taking
care not to strip the head of the screw.
Warning! Never make power connections with
a “live” wire. Always disconnect the negative
battery post before making any connections or
adjustments to a 12V power connection! Failure
to make safe, tight, high-integrity connections
can result in fire and extensive damage!
