Hello all,\n\n\nThis is an amp I purchased originally to run my front stage mids, but, alas, I couldn't fit it under my seat.\n\n\nWorks beautifully, no problems, and one of the cleanest sounding amps I have heard, as are most of the ZED designed amps.\n\nI Do not know if this is ZED made or just Zed designed. It doesn't say on the board inside. I do know that ZED made or designed virtually every one of the US ACOUSTICS amps.\n\n\nFrom What I have found for specs, here goes:\n\n150WRMS x's 2 @ 4 ohm load @12.9 volts\n225WRMS x's 2 @ 2 ohm load @12.9 volts\n500wRMS x's 1 @ 4 ohm load bridged at 12.9 volts\n\nTHD is less than .01 %\n\nS\/N is 105\n\nSize of amp:\n\n15 x 10 x 2.5 , not including the .5 inch of mounting flange on the ends of the amp.....\n\nIT IS HEAVY!!!!!\n\nVery solid construction with LOTS OF MOSFETS!!!!!\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nAsking $ 75 shipped to Con.
