Typical Installation Sequence The following represents the sequence
for a typical amplifier installation, using an aftermarket source unit or OEM Interface processor (like the CleanSweep CL441dsp). Additional steps and different procedures may be required in some applications. If you have any questions, please contact your authorized JL Audio dealer for assistance.
1) Disconnect the negative battery post connection and secure the disconnected cable to prevent accidental
2) Run power wire (minimum 4 AWG) from the battery location to the amplifier mounting location, taking care to route it in such a way that it will not be damaged and will not interfere with vehicle operation. Use
2 AWG or 1/0 AWG power wire and a power distribution block if additional amplifiers are being installed with the
3) Connect power wire to the positive battery post. Fuse the wire with an appropriate fuse block (and connectors) within 18 inches (45 cm) wire length of the positive battery post.
This fuse is essential to protect the vehicle. Do not install the fuse until the power wire has been securely connected to the amplifier.
4) Run signal cables and remote
5) Run speaker cables from the speaker systems to the amplifier mounting location.
6) Find a good, solid metal grounding point close to the amplifier and connect the negative power wire to it using appropriate hardware (use of the JL Audio ECS master ground lug,
(4 AWG), no longer than 36 inches (90 cm) from the amplifier to the ground connection point. In some vehicles, it may be necessary to upgrade the battery ground wire. (See page 5 for important notice).
7) Securely mount the amplifier.
8) Connect the positive and negative power wires to the amplifier. A fuse near the amplifier is not necessary.
9) Connect the remote
to the amplifier.
10)Connect the input cables to the amplifier.
11)Connect the speaker cables to the amplifier.
12)Carefully review the amplifier’s control settings to make sure that they are set according to the needs of the system.
13)Install the power wire fuse (80A for a single
14)Turn on the source unit at a low level to
15) Make necessary adjustments to the input sensitivity controls to obtain the right overall output and the desired balance in the system. See Appendix A (page 12) for the recommended input sensitivity setting method.
16)Enjoy the fruits of your labor with your favorite music.
Power Connections
Before installing the amplifier, disconnect the negative (ground) wire from the vehicle’s battery. This will prevent accidental damage to the system, the vehicle and your body during installation.

To connect the power wires to the amplifier, first back out the set screw on the top of the terminal block, using the supplied 2.5 mm hex wrench. Strip 1/2 inch (12 mm) of insulation from the end of each wire and insert the bare wire into the terminal block, seating it firmly so that no bare wire is exposed. While holding the wire in place, tighten the set screw firmly, taking care not to strip the head of the screw.
The ground connection should be made using the same gauge wire as the power connection (4 AWG) and should be kept as short as possible, while accessing a solid piece of sheet metal in the vehicle. The surface of the sheet metal should be sanded at the contact point to create a clean,
Any wires run through metal barriers (such as firewalls), must be protected with a high quality rubber grommet to prevent damage to the insulation of the wire. Failure to do so may result in a dangerous short circuit.
Many vehicles employ small (10 AWG -
6 AWG) wire to ground the battery to the vehicle chassis and to connect the alternator’s positive connection to the battery. To prevent voltage drops, these wires should be upgraded to 4 AWG when installing amplifier systems with main fuse ratings above 60A.
Fuse Requirements
It is absolutely vital that the main power wire(s) to the amplifier(s) in the system be fused within 18 inches (45 cm) of the positive battery post connection. The fuse value at each power wire should be high enough for all of the equipment being run from that power wire. If only the
No fuse is required or recommended directly before the amplifier power connection. If one is desired, we recommend the use of a 80A ANL or MaxiFuse™ type.
