18" BTL Box Help

[Bubbs]

Alright I am going to be buying a new car here in the next few months and want to fit 2 18" Loaded BTLs in about 8 cubic feet a piece after displacement in a 6th order bandpass. I want to put this box in a medium sized suv a little over the window line. I have a wall in my truck right now and I hate not being able to see out the back. So my question is could this fit in a ford explorer (52x40x20) and yes those dimensions are right, or would I have to go with somthing like the size of the expedition.

So again I am basically asking how much port would it take up with 8 cubic feet a piece in a 6 order bandpass?

So if there are three chambers (2 being 8 cubic feet) what should the third be. I thought I have heard before that it should be the size of both combined....but a 16ft chamber seems a little big. Some one please help!

Just build a ported box. You are really pressed for room there. Why not look at the BTL 15s. You might have an easier time fitting those.

I have heard of amzing results of 6th order bandpass if it is done correctly. That is why I am going to have TTB design it. I could do ported but I would really like to try this. I am actually going to go with the 2003 expedition. And with measurements of 50x45x26 I should have enough room. I just want to know what the middle chamber will be.
