GROUND (GND) CONNECTION
Connect a wire (minimum 10AWG – 5.3mm
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 10AWG –
5.3mm
2
) directly to the battery’s positive (+)
terminal.
2. Install a fuse holder for a 50A fuse (GX-
A604, GX-A3001) or a 30A fuse (GX-A602)
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 appropriate
fuse in the holder you installed near the
battery. (GX-A604, GX-A3001 – 50A fuse;
GX-A602 – 30A fuse)
