Trunk Box Poll

[Punkeyboozter]

How much harder is it to build a box in my trunk then building it outside first? problem is the box that appear to be good for the 2 x 12's isnt going to fit after i made a cardboard mockup

it will be for 2 x12's slotport. if not will a single 15 on a slanted box(angled to the back work fine and make my life easier)?

2x12's will be BL's the 15 will be a BTL

the last redicilous option would be a single 18 bTL flat on its back sub up port up or possibly back.

amp is an saz 3000D

any tips or tricks will be welcomed

thx
