[QUOTE="hispls, post: 8781830, member: 614752"] Where did you find coils to fit those NRT motors? I would suggest that you'll get best results if you just do a flat wall, you will maximize volume, solve a lot of potential standing wave issues you'd get from some odd shapes/angles in the rear, and simplify your options for modifying tuning after it's all up. I can't imagine you'll really have 16 cube net in a small sedan after building box to adequate thickness and counting out displacement of an adequate port. You may consider actually building the shell of the box then plan to put up the baffle last after you can get some measurements of how much space you actually wind up with and then planning cone and port area from there based on how much volume you have and how well whatever it is you plan will line up on the baffle. You may do fine with a large sealed box provided the specs of your subs work out for that alignment, dunno how you'll figure it out unless you have sourced OEM softparts and can find old published specs.
