Audio Support
PVS audio knowledge base: speakers, amps, factory integration, noise, and subs - troubleshooting first. Pair with your headunit guide when the radio is new.
Troubleshooting
-
No sound after wiring or headunit swap
Mute, source, harness orientation, and amp turn-on - in sequence.
-
Distortion, clipping, or “fuzzy” audio when turned up
Gain too high, undervoltage, and blown driver symptoms.
-
Alternator whine or buzz that follows engine RPM
Ground loops, RCA routing, and alternator/load interactions.
