Help with box volume for 2 Cerwin Vego Strokers 15" ST152D

[Shiva]

2,  15" Cerwin Vega  ST152D 

 

Cerwin Vega website recommends 2 cubic feet per woofer ported.

At the same time, the recommended box size measurements came up to 2.8 cubic feet.

For a 15" woofer, 2 cubic feet seams small.

I think a box totaling 5 cubic feet, minus port and displacements might be ok.

Please help with some advise on box volume.

This is going in a 2014 Ram 1500. I removed the rear seat behind the drivers side. Space available i s 21"W X 24-26" L X 24-38"H.

Planning on a wedge shape box.

Using a Kicker KX2400 to power both of them.

Any advice would be appreciated.
