Audio System Repair & Diagnostics in South San Diego

We diagnose and repair audio system issues, alternator whine, blown speakers, intermittent power loss, distorted bass, dead amps, popping noises, ground-loop hum, blown fuses, intermittent CarPlay drops, factory-radio integration issues, and any wiring gremlin you've got. The diagnostic process always starts the same way: we listen to the symptom, replicate it on the bench or in the vehicle, and trace the issue back through the signal path until we find the root cause. Photos of every fault are documented before any repair work begins, so you know exactly what was wrong, why it happened, and what we're fixing. Common repairs include re-grounding amplifiers to clear alternator whine, replacing burnt voice coils on subs that were running over their RMS, re-tuning gains on amps that were running too hot, replacing aging RCA cables that pick up ignition noise, and tidying up wiring runs so the system runs cleanly. We work on systems regardless of where they were originally installed. Most diagnostics are same-day. Lifetime workmanship warranty on every repair.
