Well Im really interested in car audio and Ive learned a little bit about it and I'm trying to save up for a system. So far Ive got 1 Sony XM-ZZR3301 330 watts @ 4 ohms, 600 watts @ 2 ohms, 1100 watts @ 1 ohm (Says its not 1 ohm stable but Ive seen it before!). Thinking of selling the amp though. Ive tested it on my buddies system, 2 10 pioneer in a sealed box, displacement is some where around 1.1 cubic feet.
