2017 F-150 Crew cab dual 8” sub box

[NoMoneyDM]

Good morning all. I am looking for an under the seat box for this year and body style crew cab to house 2 8” Skar audio ZVX-8” subs. I would love to just build a custom enclosure but I have seen a bunch of good looking boxes with 4 - 8” subs, but I am only looking to do 2 subs. 2.5 cu ft minimum, ported, front facing for under the rear seat of this crew cab.  
 

I appreciate your input in advance. 
 

Thank you. 
Josh
