Mounting

• Mount the amplifier on a flat, secure surface.

• Investigate the layout of your automobile 

thoroughly before drilling.

• Place the amplifier in a location that allows air to 

circulate around it to keep it cool.

• If possible, mount the amplifier vertically for 

proper heat dissipation.

• Avoid mounting the amplifier upside-down as 

this will not provide adequate ventilation for the 

amplifier.

• In order to prevent overheating, avoid covering 

the amplifier with carpet or enclosing it behind 

the interior panels.

• If the amplifier is installed in a tight area, it must 

have at least a 1-inch air gap all around for 

proper cooling.

Warning!

• Be aware of gas tanks, gas lines, hydraulic lines 

and electrical wiring when drilling mounting holes 

to prevent serious or life threatening injuries.

• Do not leave the amplifier unmounted in order to 

prevent the unit from ejecting like a projectile in 

the unexpected event of an accident.

• Do not mount the amplifier on top of wires or 

metal surfaces in order to prevent electrical 

short circuit or a fire.

• Never mount the amplifier in the engine 

compartment.

GETTING STARTED

Wiring

• Before you begin routing and connecting the 

power wires, disconnect the negative ground 

cable from the vehicle’s battery.

• Install and connect the highest possible wire 

gauge the amplifier’s terminal will accept (1/0 

GAUGE) for both power cables (+12V and GND).

• Install an in-line fuse into the positive (+) wire 18 

inches away from the car battery. It should be  

the same rating as the amplifier’s internal fuse(s)

• Route all power and speaker wires inside the 

vehicle toward the amplifier prior to mounting it.

• Avoid routing electrical wires where they are at 

risk of getting pinched.

• Use rubber or plastic grommets to protect any 

wires when routed through metal.

• Route the power cables through one side of 

the vehicle while routing the RCA audio cables 

through the other side.

• The ground connections should be as short as 

possible and always be connected to chassis 

metal. Chassis ground connection should be 

clean, rust free, unpainted and as close to the 

amplifier as possible.

Warning!

• Disconnect the negative (-) battery terminal 

before routing cables and wires to prevent 

electrical shorts.

• Never route wires underneath the vehicle.

• Do not run wires through sharp edges.

• Always turn off amplifier(s) before making any 

type of connection.
