help me build a desing

Its been long time since i been getting all my equipment and now im only a couple of weeks from it :bigclap:.

now im scared to design my own box because of the big box that is going to be and i dont want to mess up.

i have a silverado ext cab and im taking the back seat out, no one fits back there anyways .

Ok my max dimensions are 26L,24w,26h those are counting the thickness of the wood oh and i almost forgot

the subs are gonna be 2 18's DC lvl 4 with lvl5 coils. i was thinking of having the subs front and port front in the bottom tune to 32 or 33 hz

if anyone has has time to build me a design il totally appreciated.
