Box advice for sundown 15s

[Htown B.O.B.]

So I'm looking at upgraded my old stuff with new stuff. Looking at putting 4 15 sundown sa in my truck. I have roughly 61" length wise 24 from seat to back wall and 22 1/2" to stay below widow line. Is going into a 98 ext cab chevy in which the box will be the back seat. Well be run off a b2 5k. Looking for a good box design would subs up and port to drivers side wall or subs and port up good. I'm looking to squeeze as much output of the subs as possible thanks

Any help will be appreciated looking to start building soon as i already picked up the subs.

I threw something together. I ported it out the front because I liked the look better. You can port it out the side I'm sure if you are dead set on that. You don't have to use this design, I have just been practicing my sketch up skills anyway so I figured why not. It is just a brainstorm. I would actually recommend a more knowledgeable member check it before you build it if you go that route. I did not account for bracing, if you use all thread it shouldn't affect it that much, if you go with something thicker you may need to put it into torres and account for it. You will need bracing of some sort with those subs on that much power.

That's actually really nice. The port i really have no preference for just whatever gives the best output. Thanks for the input I'll look into that design I'm gonna double check measurements

It's a tight fit!  I would definitely brace with all thread due to space limitations.  One from top to bottom,  and from front to back.

I have a little wiggle room with height and depth just the length I don't

damn, honestly the length would be the one dimension that could give us more options because it would be bad ass spread the subs out straight to do subs up port up. I like the port in the middle this way because it seams more symmetrical to me. I have a box in a truck with subs forward and port out the side and love it. if you want subs forward port up you could make the baffle on the side where the port is and port through the top.

Yeah i know but i decided on 15s this time for the added cone area didn't quite take in account for the room i had to work with. My setup now is subs forward and port on the side but with the room i have to work don't think i could pull that off

I'm finally revisiting this build it's been a long time coming. After a death in the family, a move ,and a hurricane I'm more than ready to get started on this. I've got most of the electrical done, a 250 amp alt, a 3100 under the hood and 2 3400 in the back. I've changed my amp chose though will be running 2 skar episode 2000.1 d. Still need a bit a help on box design though.

What's wrong with the box above?
