GROUND (GND) CONNECTION
Connect a wire (minimum 8AWG – 8.4mm
2
) from the
amplifier’s GND terminal directly to a solid point on the
vehicle’s chassis.
For a good connection, use sandpaper to clear the
paint from the metal surface at this chassis location.
Use a star-type lock washer to secure the wire’s
connection.
POWER (12V) CONNECTION
1. Connect a wire (minimum 8AWG – 8.4mm
2
) directly to
the battery’s positive (+) terminal.
2. Install a fuse holder for a 50A fuse on this wire within
18" (46cm) of the battery’s (+) terminal. Do not
install the fuse in the holder at this time.
3. Route this wire to the amplifier’s location and
connect it to the amplifier’s +12V terminal. Be sure
to use appropriate grommets whenever routing
wires through the firewall or other sheet metal.
IMPORTANT: Failure to adequately protect the
positive wire from potential damage may result in a
vehicle fire.
4. When you are finished routing and connecting this
wire, install the 50A fuse in the holder you installed
near the battery.
