i run an ampeg svt350h head thru ampeg bse410hlf cab and im having much trouble. the head can push out 350 watts while the cab handles 400 and i cant even turn my head up half way without it clipping and the head clicks off for a couple of seconds, then back on again. i then believed it was becuz of the limiter on the head, but with that switched off as well i found trouble in the same area. now i thought that with the cab handling higher than the head, blowing out my speakers shudnt be a problem with the volume half way up, but it continues to be one. i am left to keeping the volume very low as to self-practice level volume but does not help for playing with a band. also, wen this problem does not occur, which isnt often, wen i play for an extended amount of time with the volume about half way up, everything eventually crumbles on me, as everything will sound very disturbingly distorted and my cab will start buzzing and make bubbly-like noises. its probably a long shot, but can anyone please help with some advice, as i cannot go on with this any longer.
