PROTECTION L ED COMES ON WHEN THE AM PL IFIER IS POWERED UP.

Check for shorts on speaker leads.
Check that volume control on the head unit is turned down low.
Remove speaker leads ,and reset the amplifier. If the Pro tection LED still comes on ,
then the amplifier is faulty.
The amplifier will shut down automatically when the units temperature got up to 80 C
This will protect the unit damage.

TROUBLESHOOTING

Before removing your amplifier ,refer to the list belo w and follow the
suggested procedures. Always test the speakers and th eir wires first.

AMPLIFIER WILL NOT POWER UP.

Check for good ground connection.
Check that remote DC terminal has at least 7V 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.

HIGH HISS OR ENGINE NOI SE(ALTERNATOR WHINE) IN SPEAK ERS.

Disconnect all RCA inputs to the amplifier , if hiss/ noise disa ppears , 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 input level as insensitive as possible. The best
subjective S/N ratio is obtainable this way . Try to drive as h igh a signal level
from the head unit as possible.

AMPLIFIER(S) GE TS V ERY HOT.

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 s ome applications,
an external cooling fan may be required.

DISTORTED SO UND.

Check that the Level control(s) is set to match the signal l evel of the head unit.
Check that all crossover frequencies have been properly set .
Check for shorts on the speaker leads.

HIGH SQUEAL NOISE F ROM SP EA KERS.

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

WARNING!WARNING!

1. Over high volume will damage your speake rs.

2. Be cautious when you use the amplifier nea r gasoline tank and electric wires.

3. Protect the connecting wires and parts to avoid any damage or short circuit.

4. The power must belee from the anode of the battery via FUSE.

5. The sound system must be in turning-off situation when you check the amplifier.

6. Be sure that you use the same type of FUSE when you need to repla ce it .
