I own a 2005 Scion tC with the backseat and hatch basically stripped, fully dynamatted. I have an AQ2200D for my sub stage, my highs are pretty much good. MB quart components and coax on my kicker 350.4. I need help with my substage/box. I'm running 2 t3audio t1000 10s in about 3.5 cubes, 6 inch aero. It sounds good but looking to up the cone area a little with some lower model AB subs. I was thinking 4 DX 10s/12s. Anyone have any experience with these subs? I have about 40" deep back to front, 14" high, 35" wide. Those Dim are safe measurements with an inch or two on the sides and about 5-6 inches out back. I could maybe go a little deeper or wider if needed. Anyone wanna give me some input on box/sub orientation? I wanna do subs up aero/aeros back.
