TROUBLESHOOTING
Alternator noise that varies with RPM
Poor bass response • Speakers are out of phase. Ensure
that positive and negative speaker
terminals are wired correctly.
• Check for damaged RCA cables.
• Check the radio and amplifier ground.
• Turn down the amplifier Gain setting.
Green Power LED does not turn on
Red Protect LED illuminates
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 to14.4 volt operating range.
Inspect the charging system.
• Short-circuit protection is engaged.
• Check for speaker wires shorted to
each other or the vehicle chassis.
• 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.
• Check to ensure that the Battery (+) (12
volt constant) wire has 12 to 14.4 volts.
• Check to ensure that the amplifier
turn-on lead has 12 volts.
• Check the fuses at bottom of the
amplifier. (30 amp ATC style)
