[QUOTE="Jard, post: 8476434, member: 669007"] So glad I found this sticky. My system has been running fine for 6+ years in two separate vehicles, then suddenly it acquired this problem last week. I had no idea what it was, but started taking notes on the causes of it. Made this account and was about to write up a huge post describing the problem.... but now theres no need to. Will try some of the fixes until i solve the issue. One thing to note is that I had a new battery installed (by someone else) last week, about the same time the problem arose. Could this have anything to do with it? The high pitched whirr is only present in the front speakers which are driven by their own amp. Rear speakers are driven by the head unit, and have no whirr. Edit: Just to clarify, when it says to ground the RCAs to the head unit, does that imply that the head unit should in turn be grounded to the frame of the car? [/QUOTE]
