I'm looking to get one of these either a KX or ZX 2500.1 or a Hifonics Collossus. I have up for offer, an American Bass XD1800 amp + $225, or Just (2) American bass XD1800's, I'm look'in for amps that do power @ 2 ohms so send me some offers also, and more info on the American bass amps, they can go from 12-18 volts, can be dropped down to .25 ohm, strappable, and do around 1400 - 1800 @ 1 ohm, and around 2000 @ .5 ohm and 2200 @ .25 ohm
