Amp smokes when power and ground are attached?
I have a Punch 401s Amp with power acoustik 12" sub. I got it from someone who didn't know if it worked or not. When I hooked the Power, ground and remote turn on wires it began to smoke. The head unit was off so it shouldn't have been receiving power in the first place. I opened the amp up and found a couple of blown transistors. Here is a picture of them...

There is also a transistor on the opposite side of the board that the corner is missing from.
I was wondering what would cause these to blow, and why it smokes even when it doesn't have a remote turn on signal?
Is there some way to replace the transistors and repair the amp?
Also could this have damaged the Subwoofer?
I know I asked a lot of questions there, but I'm completely lost when it comes to car audio equipment.

It probably didnt damage the sub if you didnt hear anything from the sub--- but the amp is toast. Not worth repairing. Not many places repair amps anymore. Could have been an internal short that did it.
Call fosgate and ask them how much it costs to re-board the amp. I did this with an MTX once... I sent them the amp, 55 dollars, and they put a whole new board in it. See what fosgate charges. If not, suck up and get a new amp. Perhaps the amp was abused, or someone used to low of an impedance.
Dont worry about the sub too much though, power acoustik is generally a cheap flea market brand.
