T ROUBLESHOOTING
Before removing your amplifier, refer to the list below and follow the
suggested procedures. Always test the speakers and their wires first.
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.
A MPLIFIER WILL NOT POWER UP.
Check for good ground connection.
Check that remote DC terminal has at least 13.8v DC.
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 repower it.
