least 16 gauge speaker wire, preferably a flexible multi-strand cable, such as
Soundstream Speaker 120 or Speaker 160.
C. Carefully run the positive power cable from the battery to a fuse or circuit
breaker and then to the Connect the lead to the battery via either a
fuse or a circuit breaker within 18 inches of the battery. Leave the fuse out or
the circuit breaker off until the installation is otherwise finished. If the circuit
breaker cannot be shut off manually, do not make the final power connection to
it. See chart below for recommended fuse ratings to be used.

D. Run a ground cable for the amplifier and securely connect it to a solid chassis
ground on the vehicle. The ground cable should be the same gauge as the
power cable.
E. Double check and every connection.
F. Reconnect the fuse or circuit breaker. Power up the system and the red LED
should be lit. There may be a 2-3 second delay from the time that the source
unit is turned on to the time that the LED on the amp turns on. This is normal.
Once the amplifier power LED is on and the source unit is playing, you should
have sound coming from the speakers.
Wiring Tips
l
Use grommets when running cables through any metal or sharp plastic to
prevent accidental shorting or shearing.
l
Be certain that the cables don’t interfere with normal operation of the vehicle.
l
Choose the location of the cables carefully to prevent interference with the
vehicle’s high current circuits and vehicle management systems (engine comput-
ers, relays, etc.).
LEVEL
The input levels are adjusted by means of a stereo level control located to the left
of the input connectors. When the amplifier is operated in the mono/bridged
mode, only the right channel input is active.
A. Turn the input level controls on the amp to minimum position (fully counter-

clockwise).
Set source unit volume to approximately of full volume.
Adjust outboard crossover and processor level controls so the output level of
the processor/crossover equals the input level. To do this, you can plug the
head unit outputs directly into the amplifier and listen to one amp at a time (at
low levels) to establish a reference, then add the crossover or processor and
set its gains to match the reference.
While playing dynamic source material, slowly increase the amplifier’s input
level(s) until a near maximum undistorted level is heard in the system.
