I'm more familiar with subs than amps.. so maybe one of you fine gentleman could help me. I have an Infinity Beta Digital 300, and if you're familiar with it, it's about a thousand bucks retail. I haven't had it very long, and it's worked fine until now. All of a sudden, when I get the volume up, it loses power! First I thought it overheated and cut out, but as soon as I turn the volume to about midway, the bass kicks in again. Has anyone heard of this? Any help would be very much appreciated. 1000 bucks isn't cheap, and I can't afford a new amp anytime soon.
