Typical Installation Sequence The following represents the sequence
for a typical amplifier installation, using an aftermarket source unit or OEM Interface product. 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 8 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 4 AWG, 2 AWG or 1/0 AWG power wire 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 connected to the amplifier.
4) Run signal cables (RCA cables) and remote
5) Run speaker wire 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 minimum 8 AWG power wire, 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 using appropriate hardware.
8)Connect the positive and negative power wires to the amplifier.
9) Connect the remote
to the amplifier.
10)Connect the RCA input cables to the amplifier.
11)Connect the speaker wires 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 power wire fuse (30A 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.
