• 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 low 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.

• 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.

• 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 appliciations, an external cooling fan may be required.
Di sto rt e d S o un d
• Check that the level control(s) is set to match the signal level of the head unit.
• Check that all crossover frequencies have been properly set.
• Check for shorts on the speaker leads.

• This is almost always caused by a poorly-grounded RCA patch cord.
