I have a used AB 75.1 for sale. Needs a new paintjob but otherwise it works flawlessly. I've been running it at .5ohm since I've owned it and never went into protect or got hot at all. 75w @ 4ohm and claimed to do 2200+w @ .5ohm. Has voltage mod. Asking 275$ shipping or trade/partial trade for a more powerful amp (Treo 1500.1 comes to mind)
