Problem
Audio lacks punch.
Solution
Speakers wired incorrectly, which causes cancellation of bass frequencies.
Check polarity of wires from amplifier to each speaker as defined by the
system design.
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.
