circuit.
Turn volume down from head unit to prevent overdriving the device.
Device might need service or repair, if protection LED light is still on after
resetting the device.
No sound output| Examine fuses and replace if necessary.
Examine If ground connection is intact.
Examine if remote Input has at least SV DC.
Examine if RCA audio cables are connected to the right inputs.
Examine if speaker wiring is intact.
Low sound output| Reset Level Control
Examine the Crossover Control setting.
Buzzing noise| Observe if the device is still producing noise after turning on
and off the amplifier. If yes, examine if the cables are correctly connected
and if the cables and radio are in good condition. Repair or replace if the
cables or the radio are not in good condition.
Squealing noise interference| Ensure RCA connections are properly connected.
Distorted sound output| Ensure input level of the device matches the signal
level of the head unit
Always set the input level to the lowest.
Examine if crossover frequency is set correctly.
Examine if speaker wire had short-circuit.
Amplifier temperature increased| Examine if the minimum speaker impedance for
the amp models Is correct.
Ensure good air ventilation around the device. Add external cooling fan If
necessary.
Engine noise (static sound) Interference| Usually caused by poor RCA cable
quality, which release noise. Use only the
best quality cables, and route them away from power cables.
Engine noise (alternator whine) interference| Examine if RCA cable are nowhere
