I need a 4 channel amp that puts out 65-125 watts per channel for 2 pairs of ADS seperates. My biggest issue is the size though. I've got a space where I could put the amp under the rear seat that measures approx. 8 1/2"s wide and 12 1/2"s in length with about 2 1/2"s in height to work with. I really want the best possible amp that I can purchase for my seperates. I do not want to use 2 seperate amps under the front seats because my sub amp and component xovers will go in that space.
