Owner’s Manual

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 and move audio cables away from power wires. Check power and ground connections on amplifi- er and install an in-line noise filter on source unit’s power wire. Also check the alternator and/or voltage regulator. Test for weak battery or add water to battery.
