APX480M Power System Amplifier

Problem

Amplifier fuse keeps blowing.

Solution

Incorrect wiring or short circuit. Review Installation and check all wiring connections.

Problem

Whining or ticking noise in the audio with engine on.

Solution

Amplifier is picking up alternator noise or radiated noise. Turn down input gain; move audio cables away from power wires. Check power and ground connections on amplifier; install an in-line noise filter on source unit’s power wire; check alternator and/or voltage regulator; test for weak battery or add water to battery.
