I have two Xsite XAD2K amps, one is in perfect cosmetic and working order, the other is blown (fully due to my error). The good amp is fully functional and loud, and very stable at .5 ohm. RMS wattage at 1 ohm is 2k, and supposedly will do around 2300 @ .5 ohm. The price on the good one is $250 shipped, the blown one is $90 shipped. I contacted ampjunkielikeme on this forum a couple months ago, and he said he would have to see the amp to be able to give me an accurate quote on fixing costs, but others have said probably around $100-$130 (just as a guess really though). I will post pics of both the good and bad amps later today or tomorrow morning, including board pics of the bad one. The reason it blew is because I strapped it incorrectly one night like an idiot. It may still work strapped, im not sure. I didnt want to hurt the other so I immediately pulled it out. The amp still turns on, doesnt make any funny noises, but does not have any output. It did puff some smoke when the accident happened, though, and has a burnt spot on the board. Pics up later, contact me for any questions.
