box design for trailblazer

[M82a1snake]

exclude all variables, i talking straight up box design and port design, i need opinions! i was thinking build wall for my two BTL 18's, OR just building up fire design box with maybe a CRX style port or standard slot port what you guys think??

im thinking subs up port towards hatch, port along the bottom of the box. seen a TrailBlazer get nuts at a car show last week with this kind of box

damn that did do pretty nuts! only thing is idk how to do that kind of port since generally the port needs to be 3-4inchs away from actual hatch, and my dimensions i came up with so the subs would have enough space would be too close to the hatch to put the port there so unless theres another way to give me cu . ft. that i need for the subs idk how to shorten the depth , unless i build box inside on the TB. haha
