KlubFoot Posted January 7, 2005 Report Share Posted January 7, 2005 I fixed the original problem, and have run into another... when I hook the subs up to the amp, I can only get one of them to play at a time. If I switch the RCA's then the other sub plays and the one that was playing before does not work. Any ideas here? The only thing I could think of was if my CD player was on mono instead of stereo or if only 1 of the 2 channels in the amp were working. Any other ideas? [ 07.

KlubFoot Posted January 7, 2005 Author Report Share Posted January 7, 2005 Ok, i figured it out. I checked the remote cable and it was attached when I looked at it, but when I put the CD player back in it fell off again. Quote Link to comment Share on other sites More sharing options...
KlubFoot Posted January 7, 2005 Author Report Share Posted January 7, 2005 Ok now I'm having another problem. I can only get one sub to play at a time. They both work, but only one will play at a time. When I switch the RCA's the other sub works and the other one won't. Quote Link to comment Share on other sites More sharing options...
desperado Posted January 8, 2005 Report Share Posted January 8, 2005 Bad RCA cables. Quote Link to comment Share on other sites More sharing options...
KlubFoot Posted January 8, 2005 Author Report Share Posted January 8, 2005 It's not bad RCA's because I had them installed on my previous car without any problems. Quote Link to comment Share on other sites More sharing options...

desperado Posted January 8, 2005 Report Share Posted January 8, 2005 You have a ground loop problem, and its' eating your RCA cables I am thinking. Try to get a better ground on the amp. That would be my first guess, beyond that, I am gonna lean to the idea that the female RCA's on the head unit are loosing connection somehow. Are the RCA's on the head unit a pigtail or are they soild mount in the head unit???? Also, is the radio by chance a pullout type, I realize that you might not even know what that is depending on your age, but you will know it is if that's the case. The connector on pullout chassises is known for doing wierd shit like this too. Quote Link to comment Share on other sites More sharing options...

Nitrousbird Posted January 9, 2005 Report Share Posted January 9, 2005 I'm a bit out of it, but here is what it sounds like. You say when you switch the RCA's around, the other sub will work. Try this: - Only hook one of the RCA connections up at a time; leave the other one unconnected. If each sub works on one of the RCA's (trying it on each input), but not the other, then it is definately either that RCA cable or the output on the headunit. You can verify by doing this same test again but switch the RCA's around on the head unit. - If the above proved it to be the output on the head unit (which would be my guess from the description I read), I'd suggest just bridging the amp, running mono, and running off the good RCA output on the head unit. That's the free fix and should sound fine. Of course, check your grounds for the amp, battery, and head unit, but I doubt that's the problem. Why did it work for a minute after swapping cables?? Could be a bad solder joint inside the head unit, and moving it around made a temporary contact until it heated up. Again, this is all a guess, but would defiantely be what I would look for. For the RCA to burn up, it would literally have to cause significant physical damage to the wires (aka causing it to not pass electrical current though them). I'm betting that's not the case.
