Problem Solution
Power LED does not
turn on
• Check to ensure that the yellow
constant wire has 12 to 14.4 volts.
• Check to ensure that the blue/white
amplifier turn-on lead has 12 volts.
Power LED illuminates
blue, but there is no
power output
• Advanced protection circuitry
is engaged due to high internal
temperature of the amplifier. The
amplifier needs more clearance around
the chassis. If this continues, choose a
better ventilated mounting location.
• High operating temperature can
also be caused by an incorrect input
sensitivity level. Reset the Gain Control.
The amplifier becomes
very hot and shuts
down or plays at a very
low volume
• Thermal protection is engaged.
Check for proper impedance at speaker
terminals and air flow around the
amplifier.
• Voltage protection is engaged. Voltage
to the amplifier is not within the 12 to
14.4 volt operating range. Inspect the
charging system.
• Short circuit protection is engaged.
Check for speaker wires shorted to each
other or the vehicle chassis.
Alternator noise that
varies with RPM
• Check for damaged RCA cables.
• Check the radio and amplifier ground.
• Turn down the amplifier Gain Control.
Poor bass response
• Speakers are out of phase. Ensure
that positive and negative speaker
terminals are wired correctly.
