I just hooked up my system and while car is off sounds fine, with the car on has the following problems:
During some songs more than others at some frequencies more than others there is a crackling/distortion sound from the front speakers only (mostly the tweets). Probably the sub too but can't tell as much there. It is not engine whine though, it sounds like the speakers are blown/screwed but whan the car is off like I said they are fine. What's up?
USAcustics 85x4 grounded well
2 channels go to momo component up front and 2 channels bridged to a 12"
The only thing I can think of is the power wire runs near the ECU but others have done this without issue. It's a 98 integra GSR.
