Well I put a new fuse in and it will power up now but no sound. And when I first turned it on it was humming pretty loud and make a crackling sound. No sound from the sub. So I called and talked to Brent again and he had me send a pic of the amp so he can see which one it is. He will get back with me tomorrow. Will let you all know what the verdict is. It is really great to have someone this late in the evening that will help you out. Thanks Brent and Axiom. You will not find many companies that would have tech support as late as 11:00pm.
