Need help for box plan/design

[Mills561 10+ year member]

Have an 02' Chevy Trailblazer. Searched the forum for the look I want and only stumbled across one:

http://www.caraudio.com/forum/car-audio-build-logs-cars-trucks-suvs/475810-03-trailblazer-ext-build-lots-pics.html

Original plan was 2 12"s but I think I'm going to go with a 15" or an 18" if possible. I want the sub to fire up so that there is still trunk space to put stuff on top. Unfortunately, my mind is not too creative and I need some help on what the box should look like. Along with the subwoofer, I need somewhere to put an extra battery in the back as well as the sub amp(... and possible the highs amp?)

ok dude, how much cash are you spending on this total? you could do two twelves in ported box sub up port back with max air space required and still have a cargo storage space...
