TROUBLESHOOTING

If any of the following problem occur, please resort to Troubleshooting for the possible solutions. Consult Blaupunkt authorized dealer if problem persist.

Problem Amplifier power up failure
No sound output
Low sound output Buzzing noise
Squealing noise interference Distorted sound output
Amplifier temperature increased Engine noise (static sound) interference Engine noise (alternator whine) interference

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. Inspect the fuse for damage and replace it if needed. Restart the device if protection LED light is on. 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. Check if the device continues to produce noise after toggling the amplifier on and off. 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. Typically, poor RCA cable quality is the cause of noise release.
Examine if RCA cable are nowhere near or attached to the vehicle chassis. Examine if head unit is properly connected to the wires.
