Box design for sundown x12s in semi truck sleeper

[Junior81]

I'm trying to get ideas on box design for 212s going underneath the bed in my sleeper. I wasn't sure of the port direction or speaker direction either. I have the following area to work with. 18 tall, 38 wide, 25 deep. I listen to mainly rap and decaf but want the box loud. I have a 4K amp for them. Any suggestions?

I would put one on each side and angle them out a bit, and have the port coming out of the middle. Heres a quick picture and stat sheet of what i'm talking about. I included bracing displacement for doubling up the baffle, the front, and the sides.

I can hook you up with a CAD and cutsheet. Pm me if interested.

Side firing slot port will work much better loading off a side wall under there.

Thanks for the suggestion. I like the angled design. I was thinking would a bandpass be better firing forward as all the panels underneath are thin aluminum?? Thanks guys

Also what about port area?? I noticed only 40 sq in. Shouldn't it be closer to 80 for dual??
