Ok, so I've been doing some thinking. Below the window line in the back, I have 34 cubic feet with both seats pushed all the way back and at my normal angle. That's way more room than I need for two 18's. I saw this and it got me interested: http://www.caraudio.com/forums/car-...-designs-6th-order-aq-hdc3-0-single-10-a.html

@Buck; designed it and apparently it turned out really good :)
He hasn't been on in about a year though. Who else could design something like this?

DD recommends 6.5 cubes for 18" Z's in ported boxes. I'd say I could maybe squeeze 30 cubes of actual airspace out of a 6th order. I'd just like to be able to play 25-70 hz with authority.

If anybody has experience with 6th's or knows somebody who does, would I have enough room for one?
 
If you don't have experience with 6th's I would not go building a 30 cube box. There are so many variables, it's insane. You have 2 12's right now and are reconing into 18's right? If you want to mess with a 6th, build it for one of your 12's. Make the box easy to disassemble so you can adjust it. If you are happy with it, scale it up to fit 2 18's. I would personally go with a 4th order though. Pretty straight forward and I think you know what they can do.

 
That's crazy. Like a box in a box.

That's a good idea. I'll practice building boxes with the 12's and see what ratios I like. It'll all just scale up, correct?

Like say I do a box where one chamber is 3 cubes and the other is 5 cubes. If I just make the next one 6 and 10 cubes, will it be tuned the same if I increase the port area and length by the same factor?

The bandwidth was amazing on this 6th we did. Team mate is really good with 6th orders. I loved it.
Awesome! Any more details? Who designed it? Any design tips?

It was designed and built by Jason Medlock. I don't have any tips for you as I'm still new and learning about building 4ths and 6th orders and I was at work when this one was being built.

Do you know how much he charges for a design and what his contact information is?

and holy god was it loud lol.
 
I'm going to use 2x4's for the port. I'll just add or subtract them to change tuning. I just need to decide on my internal volumes for both chambers.

Total I've spent $110 on wood so far
