[QUOTE="DrumS, post: 6233358, member: 613671"] I'm no where near the best at car audio. I know "lightweight" what I'm doing. but I have a problem that happened to my car on the way home the other day. I usually don't play my radio over 40 (volume, goes to 62), and I've had the issue with my amp overheating that my high's and mids are on (basically because I have the amp stored in the Spare Tire area on a '94 Firebird, if you know what that's like), sometimes I put the amp out of it's area to breathe better, being I live in Ohio, and summers are pretty hot like anywhere else. Ok, well this particular day, I didn't let the amp breathe as I sometimes do, and just let it rest up against the amp on my subs (which is also in the compartment for the spare tire). I know for CERTAIN, no wires we're touching, none whatsoever, just the front of the High's Amp, and the Back of the Subs amp. not laying down together, but both at a standing angle, one laying on the other. The high's amp went out, bass still played, and I usually get this when the high's amp overheats. I cut off the CD player, wait 5 seconds, turn it back on, everything back to normal. well this day, it cut off, (I'm guessing because I had the volume to 50, which I never did before) more times than usual. So I get home and park, and notice my hood is smoking (it was a rainy day, so it didn't really seem like nothing from that view), but when I lifted the hood, the alternator was burning internally, smoking real REAL bad, and I knew from the jump, I had burned the alternator coils up. but HOW!?, when this situation has happened before, same setup with the amps laying against each, high's amp overheating, me cutting the player off and back on to normal working, everything, and not once has the alternator fried itself. One guy told me it's because of the metal to metal with the amps. I totally disregarded that suggestion as I can't see that happening without SOME wire touching (ground or +12). My first thought, was first off, poor alternator (firebird's recomm. amps on alternators, 105 -which mines was-), and too much current flowing through, burned the alternator up. Maybe I'm wrong??

But maybe I don't need bigger amps, maybe it was the way things we're wired?? hell, I just need the opinions before I do the same mistake again, thinking it's just a lousy alternator (which mine did come from a junkyard -I KNOW, SHOOT ME-)...
