Operation
TURNING ON THE
AMPLIFIER
The amplifier automatically turns on a few
seconds after you turn your vehicle’s ignition
switch to ACC or ON or turn on your auto
sound system, depending on how you wired
the system. The
POWER indicator on the side
of the amplifier lights when the amplifier is
on.
Important: Your amplifier requires 5 amps or
more of power from your vehicle’s battery
during operation. To protect your battery
from discharging, do not operate the amplifi-
er unless your vehicle is running.
Note: Your amplifier temporarily shuts down
if it gets too hot, then restarts automatically
once it cools.
ADJUSTING THE AUDIO
LEVEL
For the best performance, you must set
LEVEL (MIN/MAX) on the amplifier to adjust
the level of the audio signals that enter
the amplifier.
1. Use a screwdriver to turn LEVEL (MIN/
MAX) fully counterclockwise to MIN .
2. Turn up the auto sound system’s volume
control to about one-third of its full
range.
3. Adjust LEVEL (MIN/MAX) to a comfort-
able listening level.
4. Turn up the auto sound system’s volume
control until the sound begins to distort.
Then immediately turn the volume down
to a point just before where the distor-
tion began.
Caution: Never turn up the auto sound
system’s volume control more than
needed to adjust the audio level, or
more than two-thirds of its maximum vol-
ume.
5. Adjust LEVEL (MIN/MAX) until the sound
is at the maximum level you want the
amplifier to produce.
6. Adjust the auto sound system’s volume
control to a comfortable listening level.
