Common Qestions and answers
Q: Will my subs fit this box?
A: Use your subwoofer specs compared to box specs to verify. Make sure to check for Inside cutout, outside cutout, and mounting depth.

Q: Is there enough air space for my subwoofers in this box?
A: These Subwoofer Boxes utilize what is known as a "common chamber". In the simplest terms what this does is allow you to use multiple woofers that would need a combined air space greater then that of the box yours using them in while still maintaing proper air space for your woofers and their performance. Example; Your common 8" subwoofer will require .5-1 cuft of space "per woofer" in theory your box would need to be 2-4 cuft total. But because of the common chamber in the box you can still get optimal performance with a box that only have 2.8cuft. Each individual woofer will use the combined air space rather then use the space individually. Simply, your woofers wont know the difference.

What do you have for a 2019 f350 supercab

Idk where you’re getting your displacement from.. based on 54x14x11x8 you have 2.5 cubes with 33hrz tune at best.. with the extra bracing sub displacement, what is closer to a triple baffle you got maybe 2.25 net.. with 2.5” lift.

To keep the math simple since you are having a hard time working with no square boxes in terms of volume.. (11+8)/2 give you same volume as a 54 x 14 x 9.5.. that’s a gross of 3.2 with a single baffle and .71 thick plywood.. to get to a tune of 33 you’re running 32-33” of port at what should be around 32in sq and looks to be about right here. That’s a port displacement of roughly 0.44-0.45cf. Take that away from the extreme best case volume you can even get in the given space and all you got left to work with is 2.5 net.. that’s before bracing before subs which for 8’s would be about .08 per so there goes another .32 cubes.

Your box is 2cube net😅.

Your math seems to be based on a 54 x 11 x 14 box which this is not..
