dc level 4 12 in a regular cab

[tigermax14 10+ year member]

Im going to be building a box to go in my regular cab silverado for a level4 12 and was wondering if anyone had any box designs or tips for how i can do this. I know im going to lose some leg room on the passenger side but i can deal with that. The sub has a 6.75 inch mounting depth but i dont know much top and bottom depth i will need since this will be a slanted box, and i also dont know how to calculate the volume of the box since it will be deeper on one side than the other. thanks in advance for any help

Also i dont know if I should use an aero or slot port?

prolly an aero out to the side, thats what i did in my single cab running 2 sundown E8's in a 1.2^3 tuned to 35hz with a 4" aero, worked well.

Would one 4 inch aero port be good?

depends on how small your box is for one. if you have a 4 or 5 cube box one areo would put you at some where in the ball park of 28 to 30 hz. the smaller it goes would bring that tuing up some.

The box is gonna be around 1.5 cubes
