broken rockford amps

I found a box of broken amps when cleaning my garage. Two of the amps a power 800a2 and a 100x2 both power up but have low output, and my 800a2 either blows the fuse or gets hot to the point where you cant touch it. Is there any way of telling whats wrong with these without sending them in? If not Im thinking of just adding these to the for sale thread im putting togother.

Low volume means you're not getting the gain from the transistors that you should be.

Open the amp and check for burn marks on the fet's.
