I just put a new sound system in my boat with a sony xplod sub and amp, and also an infinity reference amp with 4 kenwood speakers. The problem i'm having is that i had to run the amp power cable right past the right rear speaker and now i'm getting a lot of feedback when the engine is turned on. Is there any way to insulate the power cable so that i don't get that annoying feedback through that one speaker? thanks-Josh
It sounds like alternator whine. you're transforming into to be a rca undesirable, floor loop, or low high quality amp. attempt working a 18ga twine from the headunit chassis to the amp chassis. If this solves the concern you have a floor loop. verify all your wiring(particularly the floor and its region) and make confident your rca cable isn't pinched and contacting a floor.
You have to move that wire away from the spk. is it close to the spk, or is the wire close to the one for the spk? You may be able to block the amp wire from the spk, by placing some wood of some sort between the two( hillbilly I know but...) The other thing you can try would be to wrap the amp wire with a plastic conduit, od a foam like expanding spray foam could shield it. You can also try a magnet ont he power wire to the spk.(that may take the feed back out of it.) Or try them all at once LOL(sorry but it might work) Just try to get the wires as far away from the other as possible. Hope that helps. Cheers Wiretheworld
