I just poped the breaker that most of my home theater is on and now I get no sound from my sub's. I have the Ep 600's and they have performed flawlessly until now. Is it possable that I just blew a fuse on the sub amp? I pulled them all out and the clear ones look fine but one of them is white and I cant tell if its good. They power up fine the green light is on would they do this if the fuse was blown? Help! by the way I am running a denon 4308 for an amp and I cant even get the test tone to play through the sub's. All the other speakers work fine.
