[QUOTE="Sublym1, post: 5481302, member: 606337"] Alternator whine started happening the other day when I rolled down my driver side window. There was a loud popping sound & my HU & iPod shut off. When it came back on, the whine came on with it. [IMG]//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif[/IMG] I figured that I had a grounding issue with the wiring in the door. Finally got the time to pull the panel off this morning and found that the window regulator was rubbing against the speaker wire for my seperates. I was really considering on buying a noise filter or a ground loop isolator. While conducting my search, I came across this thread and found out that I wasn't the only one that was having this problem with my HU. After reading through the entire thread, I pulled out my HU, grounded the RCA outputs and installed it with my fingers crossed. Started the car and turned on the deck, alternator whine....gone!!
