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 lights
when the amplifier is on.
Important: Your amplifier requires 17 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 LEV-
EL (MIN/MAX) on the amplifier to adjust the
level of the audio signals that enter the am-
plifier.
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.
