Has anyone tried TurboBass Express?

If anyone has tried this could you tell me what you think of it? I'm trying to build a wall that is all funky shaped. Trying to smash 4 18's into a Ford Explorer. found this program but would just like to know if anyone else has used and what you think of it. The bottom is 37" deep x 52" wide then go to 33" deep x 18.5 " high. Top is 33" deep x 52" wide 18.5" high Grand total of 37" tall x 52" wide and the depth. Trying to utilize every bit of room I can so I can still have room for batteries and amps. Plus the ports gotta go in there to. Any help on any other programs or any ideas would be appreciated. Got it drawn out on paper. Kinda to scale it down to where it will be the same. The only chunk of cement i could use to draw on is the road lol.
