TROUBLESHOOTING
Before removing your amplifier,refer to the list below and follow the suggested
procedures.Always test the speakers and their wires first.
AMPLIFIER WILL NO POWER UP.
Check for good ground connection.
Check that remote DC terminal has at least 8.5Vdc.
Check that there is battery power оп the "+" terminal.
Check all fuses.
Check that protection LED is not lit. lf it is lit, shut off amplifier briefly and
then power it.
HISS OR ENGINE NOISE (ALTERNATOR WHINE) IN SPEAKER
Disconnect all RCA inputs to the amplifier. lf hiss/noise disappear, then plug
in the component driving the amplifier and unplug its input. lf hiss/noise
disappears, go оп until the faulty/noise component is found. lt is best to set
the amplifier input level as insensitive as possiЬle. The best subjective signal
to noise ratio is oblained this way. Try to derive as high signal from the head
unit as possiЫe.
PROTECTION LED COMES ON WHEN ТНЕ AMPLIFIER IS POWERED UP
Check for shorts оп speaker leads.
Check that the volume control оп the head unit is turned down low.
Remove speaker leads, and reset the amplifier. lf the protection LED still
comes оп, then the amplifier is faulty.
AMPLIFIER(S) GETS VERY НОТ
Check that the minimum speaker impedance for that model is correct.
Check for speaker shorts.
Check that there is good airflow around the amplifier. ln some applications,
an external cooling fan may Ье required.
DISTORTED SOUND
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 оп the speaker leads.
Check after short circuit оп the signal саЫеs.
HIGH SQUEAL NOISE FROM SPEAKERS
This is always caused Ьу а poorly-grounded RCA pactch cord.
