First off, "linking" amps is a big no-no. Secondly, "linking" amps is a big no-no. Were I you, I'd post my location, and see if anyone on the board does amp repair. And, keep your friend away from your amps in the future.

If you're real lucky, a ground trace blew out. If not, the whole power amp section could be blown.
Is the other amp still working?
If you meant what you said "im not that smart with amps", you shouldn't be fixing this one yourself.

the other amp does the same thing. Im very capable of fixing im just not familiar with solving the problem of what needs to be fixed.
its a crate GX-15 just a practice amp its all i have so i was trying to salvage it. thanks.

Oh, the little practice amps are all pretty much the same, and I would be very surprised if all that was wwrong with it was a blow output chip.
Is there a five leg TO220 on the heat sink? Number TDA2040 (or 2030)? I bet it is shot and is putting DC on the speaker.
