Disconnect all RCA inputs to the amplif ier , if hiss/ noise disappears , thenplug in the component driving the amplifier and unplug its inpu ts . If hiss/no ise disappe ars, g o on until the faulty /noisy component is fou nd.It is bes t to set the amplif ier inp ut leve l as insensit ive as possib le. Th e bestsubjective S/N ratio is obta inable this way . Try to drive as high a signal leve lfrom the head unit as possible.

HIGH HISS OR ENGINE NOISE(ALTERNATOR WHINE) IN SPEAKERS.

Check that th e minimum speake r impedance for that model is correct.Check for speaker shorts .Check that th ere is good airflow around the ampli fier . In some applications,an external cooling fan may be required.

Check that th e Level cont rol`s is set to match the signal level of the head u nit.Check that al l crossover f requencies have b een properly set .Check for shorts on the speaker leads.
