[QUOTE="B1GR3DDD, post: 8473099, member: 663137"] A few days ago I asked for help on fixing a ground loop. Well, after trying a remedy, my problems have gone from bad to worse. Here's what it currently sounds like (apologies for **** quality, had to use old flip camera, phone was full): [MEDIA=youtube]M_0fl8L23f0[/MEDIA] Breaking down what happens in case it wasn't obvious enough: -Normal high pitched whine heard at low volumes (not that it goes away at higher volumes, it just is drown out by the increased volume) -VERY loud and annoying high pitched whine at "0" volume -Loud whine and thump (from subs) when car is turned off The only way I'll fix this is isolating the problem and working backwards to fix it obviously. So I ask: What steps should I take to find the source(s) of my ground loop? [/QUOTE]
