Just wondering if anyone else has experienced this when upgrading. I have an 06 wrx and put in new amps, deck, subs. My component speakers up front are putting out a terrible alt. whine. An audio guy said that happened when he put in new amps/speakers in his girlfreinds impreza.
Anyone have this experience? If so, any suggestions on how to fix it? And by the way, I compleltely went through all the wiring and hookups, everything is fine. The audio guy suggested buying a new amp. Its also grounded fine. Had a few people look at it.
