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.

OVERHEATING
Check that the minimum speaker impedance is correct.
Check speaker shorts.
Check that there is a good airflow around the amplifier.
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.
SOUND TOO LOW-DISTORTED SOUND
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.
HIGH HISS-ENGINE NOISE IN SPEAKERS
Check that the minimum speaker impedance is correct.
Check short on power cable and vehicle chassis.
AMPLIFIER IS NOT POWERED UP
Check that there is battery power on the +12V terminal.
Check that remote terminal has at least 13.8V 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.
