Box Help 2 fi bl 18's in a 06 Tahoe

[Loflin28]

Need a little advice on a sub box for two fi bl 18's that I'm putting in my 06 Tahoe I need my back seats but the cargo area I don't care to use all that up and I don't have the 3rd row seating I need help on how big should I build the box I'm aiming at 30-32 hertz give me some input I want it loud and the amps I'm running are 2 ab Vfl 120.1's

Fi recommends 5-10 cuft per sub with a port area per cuft around 12-16. Of course the type of music you listen to would determine the port area per cuft. How much space do you have to work with in the back and what type of music do you usually listen to?

Edit: with those amps I would build the box more towards the 5 cuft per sub. Guys correct me if I'm wrong lol

I would have to get measurements in the morning but I listen to rap hip hop little bit of rock but mostly rap and hip hop

Any advice?

If you listen to mostly rap then I would go with a box around 10-12 cubic feet with a port area at 15 sq ft of port. I'm guessing you don't want to wall it so I would build a box with the subs up and port back.
