John Fassetta Posted March 8, 2014 Report Posted March 8, 2014 So today I was trying to fix my alternator whine coming through my Kenwood X-797 headunit. The noise has been there since I installed in months ago and it annoying, but not really audible with music playing. Today, I was thinking I'd find a new ground for the headunit, as I didn't know any better than to use the factory wire when I installed it. I tried swapping some of my RCA through different outputs just to see what kind of difference it made in the noise and something that I did messed the headunit up and it now SHREIKS whenever my truck is on regardless of if I put the RCA's back where they were and regardless of the ground (I ran 2' pieces of wire to a charged car battery to isolate the problem). I think I must have fried something in the headunit. Could I have touched the RCA speaker end to the outside of one of my amps and grounded the headunit through the RCA's frying it? That's the only thing I can think of that might have happened. Any suggestions would be great, I'm a pizza delivery guy who needs my system to get me through work!!! haha
John Fassetta Posted March 8, 2014 Author Report Posted March 8, 2014 Figured it out. I'd blown the internal fusing for the grounds for the RCA shields. Drop of solder ontop of it fixed it.
