Connecting the power
4/8 GAUGE (or thicker if planning for additional amplifiers) wire is
recommended for both the power and ground wires and 16 gauge for
the remote turn-on wire. Both types are available from your retailer, or
you can check-out any installation shop.
Connecting the ground
To avoid unwanted ignition noise caused by ground loops, it is
essential that the amplifier be grounded to a clean, bare metal
surface on the vehicles chassis.
Connecting the +12 volt supply wiring
Due to the power requirements of the amplifier, the power connection
should be made directly to the positive (+) terminal of the battery. For
safety, install an in-line fuse holder (not included) as close to the
positive (+) battery terminal as possible, with a fuse rating not to
exceed the total fuse values in all the amplifiers installed when more
than one amplifier is used.
Caution
As a precaution, you should disconnect the vehicle’s battery
before making the connection to the +12 volt supply wiring.
Note
The ground wire should be as short as possible (not more
than 3 ft. [1 meter]).
