Amplified Subwoofer Systems with DCD™ Amplifier 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/injury.
•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-type or quick-disconnect plugs, making it easy to remove the enclosure quickly, 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 installation. 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) battery 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 metal 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!
