I think that was confusing what i posted above:S.

To clarify so i can get some help, my amp will stay on when power and ground are connected to the amp even without a remote wire being attached. IT doesnt look as though the remote connection is touching any of the power connections so im not sure why its doing this. Any idea what i should look for on the board that would be connected to the remote wire problem?

usually the amp is turned on by transisors
and the power supply which is usually run by a 16 pin occilator chip

so should i just trace the the path coming from the remote connection and see if anything looks burnt or wrong?

Tough to see the board in this picture but can anyone point me at a possible source of the amp staying on issue?

usually most blown parts are not visable
its only when your lucky the part explodes and then you can narrow down the problem
i would highly reccomend you have somebody who knows what there doing repair the amp
you can go out and purchase all the parts
and if you miss one part you risk blowing up all the parts you just replaced
not a nice feeling trust me

thanks for the advice. If you look on the link what blew on the board is the 18 cap looking parts in the middle of the board. I have desoldered just about all of them and im gonna replace those. If it doesnt work after that im gonna be pissed but i will have a professional look at the amp.

those devices are capacitors and they probably blew form either reverse voltage
which i can't see happening as they probably after the power supply
or over voltage
usually caps have a x put in them
is it blown open?
