Before removing your amplifier, refer to the list below and follow the suggested procedures.

Always test the speaker and their wires first.

Amplifier 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.

High hiss or engine noise(alternator whine) in speakers.

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.

Protection LED comes on when the amplifier is powered up.

Check for shorts on speaker leads.

Check that the volume control on the head units is turned down low.

Remove speaker leads, and reset the amplifier. if the protection LED still comes on, then the amplifier is faulty.

Amplifier(s) gets very hot.

8

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 some applications, an external cooling fan may be required.

Distorted sound

Check that the level control(s) is set to match the signal level of the head unit. Check that all crossover frequencies have been properly set.

Check for shorts on the speaker leads.

High squeal noise from speakers.

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