i'm about to start a build for 2 dd9512's....that will be powered by a sundown 3500 in a scion xb....before i begin the build i would like for yall to tell me if you see anything wrong with this design...its a slot port but i'm used to using L-shaped ports and this doesnt have the L-shape so i'm not sure if it will have the same output....but here's the design it's 5.3cubes after all displacements, at 36.5hz, with 18sq" of port area per cube
