Firebass owners: If you turn your amp up to about 9 does it start sounding kinda bad? Mine used to be fine up there, but after I added another cab (dropping it to 2 ohms) I can't really turn it past 6. Is this normal, or is something busted? I don't think the head is the problem, I think its the cabs. They say they can take 350 continuos though, and 700/2 = 350 each, so I don't know what the problem is.
