Trouble shooting
This power amplifier has protection features to prevent any damages from misuse or faulty
conditions. If the unit senses excessive heat, short circuited speakers or overload, the protection
indicators will light, and the system will be turned off. In order to check the occurred problem,
you should turn all levels down and all power off and carefully check the installation for wiring
mistakes or short. If the amplifier shuts down due to excessive heat, the protection indicators will
not light : simply allow time for the unit to cool.
Before removing your amplifier, refer to the list below and follow the suggested procedures.
Always test the speakers and their wires first.

Check that there is battery power on the +12V
terminal.
Check that remote terminal has at least +12V
DC remote connection.
Check a good ground connection. Check all
fuses.
Check the protection LED is not lit.
Check shorts on speaker wires.
Remove speaker wires and reset the amplifier.
If the protection LED still comes on, then the
amplifier is faulty.
Check that the minimum speaker impedance is
correct.
Check short on power cable and vehicle
chassis.
Check that the minimum speaker impedance is
correct.
Check speaker shorts.
Check that there is a good airflow around the
amplifier.
Check that the input level control is set to
match the output level of the unit.
Check the head unit volume.
Check speaker shorts.
Check that crossover frequencies have been
properly set.
Check a good ground and for speaker shorts.
Disconnect all RCA inputs from the amplifier.
If hiss/noise disappears, check it with a good
RCA interconnect. Then check the component
driving the amplifier.
