kenwood kac7220 amp problem

[jibbers93gt]

I installed this amp in my truck and everything was working fine....then i accidentally touched a bridged speaker wire output to the case of the amp with a screwdriver. (I thought I had the speaker wire outputs backwards and was going to change them)

Now, you turn the key on and the amp power light comes on for 1 sec or so and the power light goes out and the sub doesn't work of course.

Anyone know what I might have damaged?

I have a pretty good background in electronics and have a meter and such if that helps.

I put my old 10" sub and amp setup back in there and it works perfect.

Thanks for any help.
