OPERATION
TURNING ON THE AMPLIFIER
The amplifier automatically turns on whenever you turn your vehicle’s ignition
switch to ACC or ON. POWER lights when the amplifier is operating.
SETTING THE LEVEL CONTROL
For the best performance, you can adjust the level of audio signals that enter the
amplifier by following these steps.
Cautions:
• When the amplifier’s internal temperature reaches 202×F, the automatic
thermal protection system lowers the amplifier’s output power until it cools
down.
• The sound distorts if any output channel shorts. Turn off the amplifier and
try to locate the short.
• To prevent draining the vehicle’s battery, do not operate the amplifier using
the ignition switch’s ACC position for too long after turning off the vehicle’s
ignition.
