Amplifier Fuses
Although the amplifier has internal fuses, 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 connected 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 as a minimum. 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 4mm 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 insula-
tion is worn through and the power wire is shorted to ground.
Remote Input Connection
Connect the REMOTE trigger lead from the head unit to the amplifier using the
3mm hex wrench to tighten the connector on the power block of the amplifier.
(refer to the diagram on page 3).
Speaker Output Connection
Prepare each wire by stripping approximately
5
⁄8” (16mm) of insulation. The pos-
itive (+) speaker wires are installed into the amplifier terminal marked “SPEAK-
ER OUTPUT” / “+” (refer to the diagram on page 3). The negative (–) speaker
wires are installed into the amplifier terminal marked “SPEAKER OUTPUT” /
“-”. T
ighten the “SPEAKER OUTPUT”, “+”, and “-” terminals with the supplied
2mm and 3mm hex wrenches 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.
WARNING! Front and Rear Speakers impedance must not fall below 2-ohms
Stereo / 4-ohms Mono. Subwoofer impedance must not fall below 2-ohms.
