I have 4 MTX 4000 12s in my 96 hatch. Now i have one sealed box of two in the far back facing up, an empty bandpass box on its front to take airspace and bolt amp to, and another sealed box where the rear seats used to be. I want to somehow move all 4 to the back so i can use the rear seat area to put my air ride system, but dont know what the ideal box design would be. i not only want good sound, but the ability to add 2-4 more(I want to have a good show and decibel drag system). If anyone could tell me what the best direction to face the subs to get the best sound, i would greatly appreciate it.
Thanks in advance

With 4 12's you can probably face them up or build a wall. The box will easily consume all your trunk space. I would say face them up, make the box at least a foot high, and you can get a pair on the front assuming you are not out of airspace.
