Troubleshooting

Examine your wiring diagram and refer to the following table for possible problems and solutions. Consult an authorized Blaupunkt dealer if problems persist.

Problem	Solution
Amplifier power up failure	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.
Protection LED lights on when amplifier turn on	Examine 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.
No sound output	Examine fuses and replace if necessary. Examine 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.
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 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 near or attached to the vehicle chassis. Examine if head unit is properly connected to the wires.
