man I finally got my system installed today . I have 1 15" memphis 15-PR154 and a Power Acoustik GOTHIC OV2-1200 http://www.shopping.com/xPF-Power_Acoustik_Gothic_OV2_1200 on it. The sub is in a vented memphis box and this stuff is droppin compared to what I use to have. I have everything on the amp turned down and I cant stand turning it past volume 10 on my Pioneer DEH-1600 . Power ... I love it. All I need to do now is get some DYNAMAT
