Trying to find a good quality low budget mono amp for my sons system, (4) DVC 2ohm P310's, Ported box tuned to 38 hertz, power wise 2000 watts stable down to atleast 1 ohm, or 2-1000 watts amps. He has mentioned some amp names but we dont know much about these Sound Stream, Lanzar, and Hifonics, looking for amp that will really make these P3's Rock Hard, Please give names and series of any amps, Thanks.
