Center console speaker box questions

I think I've come to settle on a design for a Tline. Length was really my only variable that could be changed without compromising my requirements. The width is the same width as the middle seat, and I wanted to keep the height as minimal as possible. Speaker mount area will require a double baffle of sorts since the mounting depth of the speaker is 6" and it's going into a 5" deep cavity.
18 x 36 x 13.5, .75" MDF
~105" port length with a 5x12 port. Tuned to 32Hz.

Thanks fastford, I am putting a lot of time into this. The more I research how and why my old box performed the way it did the more I find it's actually pretty easy to calculate (assuming I'm calculating right). I'm doing the most basic calculations to design the box however since small differences such as the vehicle, where the box is located in the vehicle, speaker specs etc all have an effect on the output. The effects can be small and indistinguishable though, but there are many variables that can be factored into a box setup to help fine tune it more than basing the box off of the speakers Fs (or your desired tune frequency). I however don't want to dive that deep into this research. Right now, my biggest question is how will the loading be effected with a front or rear firing port?
Anyhow, I have another design I might post and ask about that allows me to add some cup holders to the box that would replace the ones that will be gone when I remove the center seat. Though the design would have to have the port length extended just a bit. But I'd still like to see Logan's that he said he's going to post.

Thanks Logan, I know how the busy schedule goes.
I haven't given this enough thought, as I haven't even given down firing subs a chance yet. I'll go back to the drawing board and rethink some stuff up.
Whats the specs on that box if you don't mind?

i dont remember exactly, it was a 32hz tuning i know that, and was about 4 cubes net before displacement of the sub/port's
downfire boxes improve sound quality and cuts down on flex, good for someone who wants good "clean" sound, when you build your box, especially tlines make sure you 45 degree the corners, you wouldnt believe the difference in sound vs 90 degree angles

Yah, I know about the 45's... I just haven't taken the time to learn how to model them in sketchup.
Can you clue me in on how the wave guide in that box flows? I'm having a hard time picturing it doubling back on itself twice (like my box at the very top of this page) with that box... if that's how it's designed anyhow. I can't see how you'd get the length for a 1/4 32Hz wave if it isn't.
