what would be the best box design for my GP. 2 SQ HDS212 will be running on a SQ1200 unless I find a better deal on something 1200-1500rms 1ohm..4 door. don't plan on removing the back seat or anything. and I plan on keeping most of my trunk space (Box Wise) so trunk facing, cabin facing, ported sealed, sub uptop.. ect..??
