called a sledge hammer box(almost like mtx version, slams hard and good for competeing but as said before in thread fire it backwards for best results. The ports are like in an L shape going back. the speakers don't share air space. Its basically how they make the sledgehammer box. I would definetly look in to making one of these. if you would like to let me know and i can help with the dimensions and how to make. I haven't carpted it yet because i'm trying to find viynl that matches my leather. the vinyl will had the minor inperections of the box. If you want more information you can goto MTX and JL website they kinda of give you the intructions on how to make it, but also depends on what subs your using and how ur have it wired/ohms.
sorry i disagree with that comment....best possible way is sound bouncing off tailgate and returning...that is why hatchbacks are the loudest.....and if you are going for just db's u might want to think about just keeping it sealed....port is louder but wont "hit" like a sealed box will...
