so, your big plan is to take over this guy's thread, and groan on every post i make? that's some brilliant stuff there. me scared. you have not helped at all, so gtfo. there is cause, and effect. you can argue it all day, but what happens cannot be changed by any amount of bantering. besides, it's not really "amps" but has to do with the specific amp itself. as to "low voltage protection" some have it, and many don't even need it. often times the op-amps/ic's cannot function at all, and the power supply is just off, not in protection, as in, min.10.5v for it to even do anything, some, are lower, and i have personally taken them down in the 7's 'eh, i gotta go to work. bye
