Symptom
Possible Remedy
Amplifier
will not
power up
Check to make sure you have a good ground connection.
Check that there is battery power on the (+)terminal .
Check all fuses, replace if necessary .
Make sure that the Protection LED is not illuminated.
Protection
LED Comes on
Check for short circuits on speaker leads.
Check the speaker load not beyond the minimum load.
Remove speaker lead, and reset the amplifier. If the protection LED still
Comes on, then the amplifier is faulty and needs servicing .
No output
Check that the RCA audio cables are plugged into the proper inputs.
Check all speakers wiring.
Check the headunit output and the amplifier level setting.
Low output
Reset the level Control.
Check the Crossover Control settings.
High hiss in
The speakers
Check the RCA cable is not shorted to power ground at amplifier side.
Check the amplifier grounding.
Distorted sound
Check that the Input level control is set to match the signal level of the head
unit. Always try to set the Input level as low as possible.
Check that all crossover frequencies are properly set.
Check for short circuits on the speaker leads.
Amplifier gets
Very hot
Check that the minimum load impedance for the amplifier model is correct.
Check that there is good air circulation around the amplifier. In some
applications, It may be necessary to add an external cooling fan.
