NEED HELP! 2006 GMC sierra extended cab

[TyWilliams 10+ year member]

Hey guys I need some help. I'm fairly new to Car Audio but am already becoming a enthusiast. I want to run, preferably, a pair of Fi BL 10's ported somewhere in the range of 32-32 Hz. As you know there is not much room under the seat of a extended cab truck, but I have seen it done. This is all I have found as far as a ported 10 design goes, but its for one: View attachment 26538913

I want two. The minimum space needed is .7 through 1.5 cubes. I have seen sealed boxes built as big as 1.12 cubes(SubThump Ultra deep MAXX) so I should be able to get at LEAST .7 after displacement. so now I need help with the design. I was thinking subs up port out, Anybody smarter than me know how to make this work?

Seat lift woukd clear up a bunch of space. Use fiberglass for top and bottom of box to save space.

I think it was 'ado' who built a nice ported box for single 12 under seat. T4y to find his build thread and that may help
