Custom box design for 4 Fi SSD15s in 09 Tahoe - Will pay

[kurb]

Whats up guys. I'm looking for an -expert- to design me a box for my 09 tahoe for 4 Fi audio SSD 15s. I plan on powering them with a single Incriminator Audio IA30.1 amp. Dual 2 ohm subs wired to 1 ohm load. Anyone interested? I would be willing to pay for the box design and guarantee I will not be entering any SPL competitions, I live way up in the UP of michigan years from major cities haha. I just want the loudest shit around 😎 For my personal enjoyment. (I live in a small area so it will be lol) Thank you fellas. I know yall know the size of a tahoe, im sure 20 cubic feet is easily doable I will not be using my 3rd row seats just my back captains seats. And they usaully are folded forward. My current box is 36" from the back door and 39" wide and it fits perfect between the back seat mounts. So thats a good dimension baseline. 39x36xXXX height! up up up and away. I like lows i'd like a tuning of 30-32 hz..
