[QUOTE="jroot, post: 346721, member: 551458"] Hi, I'm new to the board, it looks like there is a lot of people here who know there stuff, so I figure I'll post a problem I've been having (yes, I've done some searches as well).... I'll start by naming my system components.. Head Unit - Alpine 9815 Amp - US Acoustics USB-4085 Infinity Basslink Speakers - Infinity Kappas around (2 5 1/4's, 2 6x9's, 2 3 1/2's) So my problem is if I have my engine running I get a static noise through my speakers which are hooked up to my amp. I won't get this noise if I don't start my car (Volvo 850). So I only get the noise when the engine is on and also when I turn off my car but not completly, the static will get more severe. I have my amp + basslink grounded in the same spot. Power + Remote wires running on drivers side, and all other wires on the other side. I don't think anything is wrong with my audio wires at all. I'm using 8 gauge power and ground for both amp and basslink, 14 gauge or 12 gauge for my speakers. I've tried just about everything I can think of to fix it, switching ground points, just lying the rcas over the seats, trying a different head unit (i haven't tried a different amp, so it may be the amp?), and numerous other things... Someone told me that the static noise is coming in from the power line, and I need to get 4 gauge but I think 8 gauge is good enough, but maybe i'm wrong?? Also crutchfield gave me a suggestion to run my ground from the HU back to the amp location ground to eliminate the 'ground loop'. So anyone have any other suggestions? :-) I even checked my ground which I think works in theory by hooking up jump starter cables to a good grounded car to my car thinking maybe my car didn't have the best ground but the static still remained there.
