I have a 620 W amp and it has been great until about a week ago. I had two 12", 4 ohm subwoofers hooked up and then all the sudden all the power went away. So i unhooked one of them and wired the amp and sub for one sub, and all the power was back. Then i did the same with the other sub, just by itself, and it worked too. So i tryed to bridge them both and all the power went away again. I cant figure out y my amp can only work with one sub now, even though i have always had it with two. Can someone please help.

It sounds like one of the channels is not working. Either you blew one of the channels on the amp, or the rca to that channel is not working.
Are the Two speakers bridged when they are both hooked up? Are they run in parallel or series?
Make sure that the rca's are ok and that you are bridging on the right channels.
The other option is that when you are bridging the subs in series you are creating a load that the amp can't handle and it is going into protection. Try hooking the subs in parallel or wiring them stereo.

If your subs are 4 ohms (total) each and you wire them in parallel that comes out to be a 2 ohm load on your amp. Your amp may not be able to handle that much of a load any more (compromised a component by driving it too hard).
