Amp help

it might not be the amp that is not working it could be the sub or sub's. Try takeing a sub out of the box and look down the hole in the center of the magnet on the back of the sub and look and see if you can see any wire's or any thing that has come unwound in the sub and if you do see wire's then you have blown your sub. If you dont see any wires then you could completly disconect your amp for 20 to 25 minutes and then plug it back in and see if that fix's your problem. If none of this works then you can take your amp to an audio store and have them test the circut board in your amp.
