Installation - Wiring
Amplifier Fuses
Although the amplifier has an internal fuse, additional fuse protection should be installed as close as possible to the battery on the positive (+) power wire going to the amplifier. An inline fuse should be installed at no more than 18" (46cm) on the positive (+) power wire. The rating of the inline fuse should equal the value of the internal fuse of the amplifier if only the single amplifier is connected to this wire. If other devices are con- nected to this wire, the fuse value should be of sufficient capacity to handle the demand.
Wire Gauge
The amplifier accepts up to 4-gauge stripped wire at the DC power and ground input terminals, and 4-gauge is recommended. Wire runs should be kept to the minimum practical length.
Power 12v and Ground (GND) Connection
Strip approximately 5⁄8" (16mm) of insulation. The positive (+) power wire is installed into the amplifier terminal marked “12v”. The negative (–) wire is installed into the terminal marked “GND”. The ground wire should be as short as possible and connected directly to the chassis of the vehicle. Make sure that the chassis connection point is free of rust, grease, dirt, paint, and other materials that may insulate the ground wire from making proper connection. Tighten the 12v and GND terminals with the supplied 3mm hex wrench to secure the wire into the terminals. If the power wire must be routed through a drilled or existing hole, use a nylon panel grommet to prevent the insulation from fraying. Failure to do so could lead to an electrical short if the wire insulation is worn through and the power wire is shorted to ground.
Remote Input Connection
Use the supplied FEMALE quick-connect terminal to connect the REMOTE trigger lead from the head unit to the amplifier. Crimp connector to wire from head unit that controls remote turn-on (refer to head unit owner’s manual). Once the quick-connect terminal is crimped into place, carefully push connector onto recessed MALE REMOTE terminal adjacent to the RCA input pair (refer to the diagram on page 4).
Speaker Output Connection
Prepare each wire by stripping approximately 5⁄8" (16mm) of insulation. The positive (+) speaker wires are installed into the amplifier terminals marked “SPEAKER OUTPUT” / “+” (refer to the diagram on page 4). The negative (–) speaker wires are installed into the amplifier terminals marked “SPEAKER OUTPUT” / “-”. Tighten the “SPEAKER OUTPUT”, “+”, and “-” terminals with the supplied 2mm hex wrench to secure the wires into the terminals. If the speaker wires must be routed through a drilled or existing hole, use a nylon panel grommet to prevent fraying the wire insulation. Failure to do so could lead to an electrical short if the wire insulation is worn through and the speaker wires are shorted to ground.
Mono Subwoofer Operation
Refer to the diagram on page 4.
WARNING! Subwoofer impedance must not fall below 2 ohms when in MONO mode.
