i have a polk psw303 sub. i swapped my ed 9kv.2 into it to compare it to the polk sub. well like a ******* when i was putting the polk sub back in i didnt unplug it and the + & - leads touched. :suicide:
the fuse in it blew. so i ordered some new ones exactly the same and now as soon as i plug it in it pops the fuse, even if the amp is turned off. i dont want to send it in to polk as they would probably charge way to much to fix it. i could post pics if it would help.

Pictures would help...

Sounds like something in the output is cooked... Have you looked for shorts or measured the impedance in the transistors?
