POWER WIRING
BATT+ (Power)
This amplifier should be wired directly to the vehicle battery using the appropriate size cable. Start at the
vehicle battery and run the power cable through to the amplifier. Avoid running the power cable over engine
components and near heater cores.
The use of an inline fuse or circuit breaker is a must ; this will pre-
vent the risk of a potential fire caused by a short in your power cable. Connect the fuse holder or circuit breaker
as close to the battery positive (+) terminal as possible (within 18” from the battery). This fuse or circuit breaker
should be no greater then the sum of the fuses found on the chassis of your amplifier (also see specifications
chart). You may now connect the cable to the battery, but remember to leave the fuse out or circuit breaker
“off” until all other cable connections are made.
GND (Ground)
When grounding your amplifier, locate a metal area close to the amplifier that is good source of ground
(preferable the floor pan). Use a short length of cable the same gauge as your power cable. Once again,
investigate the area you wish to use for electrical wires, vacuum lines, and brake or fuel lines. Use either a
wire brush or sandpaper to eliminate unwanted paint for better contact of the ground.
NOTE: If installing in
a boat, UTV or motorcycle make sure your ground wire is connected to the negative ( - ) terminal
of the battery. See Fig. 5
Secure the ground cable to the body using a bolt, star washer and nut. Spread silicon over the screw and
bare metal to prevent rust and possible water leaks.
For Power Sport applications such as UTVs, motorcycles and boats it is highly recommended to wire both
the Ground (GND) and Positive (BATT+) cables from the amplifier directly to the battery.
NOTE: The Ground
must be capable of carrying the same amount of current as the positive wire.
Now it’s time to connect the power and ground cables to the amplifier.
Cut both cables to length.
Strip off 1/2 inch (12mm) of the insulation so that the bare wire fits all the way in the terminal block on
the side panel of the amplifier, seating it firmly so no bare wire is exposed. Use a screw driver to losen the
BATT+ and the GND connection on the amplifier. Insert the ground first, and then the +12V and please make
sure that you place them into the correctly marked terminals. Hand thighten the set screws and make sure
the connection is secure to prevent possible arcing due to loose screws.
