Before removing your amplifier, refer to the list below and follow the
suggested procedures Always test the speakers and their wires first.
Check for good ground connection
Check that remote DC terminal has at least 8 5Vdc
Check that there is battery power on the
terminal
Check all fuses
Check that protection LED is not lit If it is lit shut off amplifier briefly and
then power it

Disconnect all RCA inputs to the amplifier. If hiss/noise disappear, then plug
in the component driving the amplifier and unplug its input. If hiss/noise
disappears, go on until the faulty/noise component is found. It is best to set
the amplifier input level as insensitive as possible. The best subjective signal
to noise ratio is obtained this way. Try to derive as high signal from the head
unit as possible.
Check that the level control is set to match the signal level of the head unit.
Check that all crossover frequencies have been properly set.
Check after short circuit on the speaker leads.
Check after short circuit on the signal cables.
