GETTING STARTED

Mounting

• Mount the amplier on a at, secure surface.

• Investigate the layout of your automobile
thoroughly before drilling.

• Place the amplier in a location that allows air to
circulate around it to keep it cool.

• If possible, mount the amplier vertically for
proper heat dissipation.

• Avoid mounting the amplier upside-down as
this will not provide adequate ventilation for the
amplier.

• In order to prevent overheating, avoid covering
the amplier with carpet or enclosing it behind
the interior panels.

• If the amplier 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 amplier unmounted in order to
prevent the unit from ejecting like a projectile in
the unexpected event of an accident.

• Do not mount the amplier on top of wires or
metal surfaces in order to prevent electrical
short circuit or a re.

• Never mount the amplier in the engine
compartment.

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 amplier’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 amplier’s internal fuse(s)

• Route all power and speaker wires inside the
vehicle toward the amplier 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
amplier 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 amplier(s) before making any
type of connection.
