Solution
Examine if the ground connection is intact.
Examine if remote input has at least 5V DC.
Examine if battery power is connected correctly to the + terminal.
Ensure supplied voltage is minimum 12V.
Examine if fuse is broken and replace if necessary.
Restart the device if protection LED light is on.
Examine if speaker wire had short-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.
Examine fuses and replace if necessary.
Examine if ground connection is intact.
Examine if remote input has at least 5V DC.
Examine if RCA audio cables are connected to the right inputs.
Examine if speaker wiring is intact.
Reset Level Control
Examine the Crossover Control setting.
Observe if the device is still producing noise after turning on and o the
amplier. 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.
Ensure RCA connections are properly connected.
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.
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.
Usually caused by poor RCA cable quality, which release noise. Use only the
