POWER WIRE & FUSE
The proper wire size is very important for an amplifier capable of these power
levels. The following are the recommended fuse values and wire gauge for lengths
up to 20ft.
POWER
Power wire needs be connected directly to the battery using the wire requirements
listed above. Never use the fuse box or any other wire as a source for the power
for an amplifier. Before you start, choose the easiest path to run the wire from the
battery to the amplifier. Generally, try to keep the power wire on the driver's side of
the vehicle (See Signal Inputs & Outputs for explanation). Use the following rules
for running the power cable through the vehicle:
1. Use grommets when passing the power wire through any metal wall of the
vehicle.
2. Avoid sharp corners or sharp body parts that may easily cut through the
insulation on the wire.
3. Avoid running the power wire over engine components and near heater cores.
4. Avoid the gas, brake and clutch pedals and their mechanisms.
5. Use an inline fuse to eliminate the risk of a fire caused by a short in your power
wire.
6. Connect the fuse holder as close to the battery positive as possible.
Once the wire has been run, connect the wire to the battery terminal. As a
precaution, leave the fuse out until all other wire connections are made.
GROUND
The wire used for ground should be of the same gauge as the power wire. Make
sure that you choose a different color (generally black) so that you don't reverse the
polarity at the amplifier terminals. Follow the rules below for connecting the ground
wire properly:
1. Avoid using seat bolts, seatbelt bolts, and fender wells for ground.
2. Choose a metal area close to the amplifier that appears to be a good of ground,
such as the floor.
3. Investigate the area you wish to use for electrical wires, vacuum lines, and brake
or fuel lines.
