rebuild american pro sub?

I have a sub that my buddy gave me, it is an american pro 1000w 12" but I think he smoked it.  He said it smoked and smelled like burnt wire.  It still moves, but sounds like death...  It is in like new shape still, is it possible to rebuild it?  Can I just rewire it together?  What exactly happened?

Have you ever pulled apart an amp? I have several times and they are a nightmare if you dont normally work on them. I had to replace my Power Acustik 1600 watt 2 channel amp like 4 months ago. The amp was the blue saphire one that has the blue neon in it when it turns on. I had the amp for over 4 years. Anyways, something went wrong with it internally where when I would go over bumps or anytime the amp would bounce just alittle, it would cause the subs to make a "bump" sound. Sometimes it would shut up for awhile but other times they would bump then sound off like ground loop (whining from alternator, but deeper bass sound) and stay like that until I hit a bump in the road. At first I checked my power, ground, and remote wires running to the amp for connection. That was all fine. Took the RCA's and ran them to another amp, worked fine. Pulled the amp out and tried a friends for 1 week, and worked fine. So I knew it was the amp itself. I then took it apart to see if the ground connect in the amp was fine. No loose connections or burnt wiring. And it is basically impossible to check if any chips are fried without having the amp hooked up and test each chip itself. Now reguarding your amp, I do know that each amp has capacitors in it. Mine had 10. And I was told that when you overpower the amp, those capacitors can and will fry. Not all at once, but maybe one at a time. And as they slowly burn out, it  puts mroe stress on the ones that are remaining. Now it could be that you fried some of those, which would be the reason of why the amp still works yet doesnt really do much. Those capacitors are cylinder like about 1/4" in diameter, up to 1" in length and mounted vertical. Only problem is that there are other chips that look like that also.

wow... I believe he is asking about rebuilding a sub, nice little rant on amp repair there though.

I am not sure those subs are rebuildable... I am lookin at prices right now, and I think your better off just buying a new one.

Yes, you can have a sub rebuilt or you can do it yourself.  It's called "re-coning."  Contact the manufacturer first to see if it's a service they offer.

For the companies who offer the service, when compared to the cost of a new speaker, no.

Hey guys, I have been gone for a few days, just got all the replies...  Thanks for all the info, and about the amp thing, pffff, forget about it...  No, I have been in an amp before, big pain, I know...  And to DYohn, thanks, I will get a # and call American Pro, but I am thinking that being that they aren't as big and popular as many other brands, they may not be able, also, it is a little bit older too, so its a great idea, but questionable...  My reasoning was laying with the fact that the back of the sub came out of the box with a vent screen and bolted together with allen-head bolts...  So that might be a sign that it could be fixed...  Thanks for the help guys!

anything smaller than a 2.5" vc dont bother u will be wasting ur money and time. american pro is a sound around product = pyramid co. save ur money and buy a good sub...
