TROUBLESHOOTING

PROT (Protect) LED Comes On, Amplifier shuts down

Possible Cause

There is a short in the system

Amplifier has exceeded normal operating temperature due to improper ventilation.

Speaker impedance too low

Low battery voltage

Solution

Turn the system off. Check connection to all components for possible shorts. Check all wires and cables for kinks, splices, poor insulation, etc. Repair/replace if necessary.

Turn the system off and allow to cool. Verify adequate ventilation around amplifier. Move the amplifier to a spot with better ventilation if needed.

Check for proper speaker impedance, replace if needed.

Check that the vehicle charging system is maintaining proper voltage.
