Hard to describe in a title but heres the deal. I hooked my speaker up before it was in the door to make sure it worked and it did. Woo. So I set it in the door, and start screwing while its still playing. I screw in the top first or something, and then I goto screw in the opposite side. Naturally this is moving the speaker a certain way as I screw it. Well all of a sudden the speaker goes out, and the music is crackly and vague. Then if I pull out a little, taking pressure off of the speaker on one side, the music comes back on crisp and clear and full. Let go, back to crackly.

This process ends up blowing the right channel on my amp. What is going on here? I always wrap the terminals and connectors in electrical tape, so thats not it. Is somtehing else touching metal back there, shorting something out, and thats blowing the channel on my amp, or what? Any ideas I would appreciate them, thanks.

Maybe the voice coils are being hit by something

had the same thing happen once in a nissan sentra. the mounting surface for the factory speaker wasnt perfectly flat and the speaker got torqued just slightly and it caused just enough misalignment that damage occured...

firstly, dumb idea to work on amps or speakers while the battery is connected, let alone while the system is in use.
secondly, when you pushed the speaker in, you shourted out the speaker to the car chassis.. one of the terminals or both or them were touching the car body/door metal. this shorted out the amp channel and probably killed the speaker too.

This started to happen in my Monte Carlo... When I was screwing it in I noticed it wasnt flush so I used a washer behingt he speaker to compensate...

yea i did the same thing once i got a new set of speakers. this was way back, my first install where i thought i had something...looking back it was hilarious but at the time i thought it rocked and really for my area of the country in 1989 it did. it was a kraco pull out tape deck, a couple of pyramid amps, one running a set of pyramid three way 6.5 in the doors and the other running a prefab pyle pounder 10" box, a set of pyramid 4" mids and a set or pyramid piezo tweeters through a passive three way pyramid crossover setup. the mids were mounted in the rear deck and the tweets were just laying back there in the corners of the rear deck........man that shit was just amazing to me and my friends, they couldnt figure out how i got it all hooked up
