none of those actually have that wattage and probably will sound bad.

I'd look for a used phoenix gold 4ch amp (octane line) off of ebay or something, they have some damn good quality stuff.

I'm selling my old one to a friend, I wanted to sell it here but i felt bad selling it to someone on TR for 40 bucks because it had a bad input on the rear inputs, so im selling it to a good friend of mine for 80 instead.
