If it is lit, shut off amplifier briefly and then repower it. High hiss or engine noise (alternator whine) in speakers. • Disconnect all RCA inputs to the amplifier(s) – if hiss/noise disappears, then plug in the component driving the amplifier and unplug its inputs. If hiss/noise disappears, go on until the faulty/noisy component is found. • It is best to set the amplifier's input level as insensitive as possible. The best subjective S/N ratio is obtainable this way. Try to drive as high a signal level from the head unit as possible. Protection LED comes on when the amplifier is powered up. • Check for shorts on speaker leads. • Check that the volume control on the head unit is turned down low. • Remove speaker leads, and reset the amplifier. If the Protection LED still comes on, then the amplifier is faulty.

Always test the speakers and their wires first. Amplifier(s) gets very hot. • Check that the minimum speaker impedance for that model is correct. • Check for speaker shorts. • Check that there is good airflow around the amplifier. In some applications, an external cooling fan may be required. Distorted sound • Check that the Level control(s) is set to match the signal level of the head unit. • Check that all crossover frequencies are properly set. • Check for shorts on the speaker leads. High squeal noise from speakers. • This is almost always caused by...
