I have 4 12" Kicker Comp VRs in my Durango right now. I'm going to redo everything for competition next year. I'd like to do a wall using 6 12" Comp VRs. Each two will be wired at 1ohm to 3 Memphis 1000D. I know I can fit them in the car ported but I think if they are aiming forward towards the windshield it will be good for SPL competition but sound like crap when I'm driving around. If the wall is aimed towards the rear hatch, it will block most of the air pressure in the back and wouldn't be as loud in competition. Am I wrong about this? Please leave me any suggestions you have about this wall.
