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 prevent 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). 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
Fig.5 Proper Chassis Ground
Connection For Cars And Trucks
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 o 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 hex screw driver to lose the BATT+ and the GND connection on the amplifier. Insert the ground first,
and then the +24V and please make sure that you place them into the correctly marked terminals. Hand tighten the set screws
and make sure the connection is secure to prevent possible arcing due to lose screws.
