Need help with sub box design

[300spartan]

I’m gonna be using a sa v2 15 d2 on a skar rp 2000.1. My car is a 2013 Chrysler 300. 
in the Chrysler’s there is two bumps on the floor which takes away some floor for the enclosure. In between the bumps I can get 32 by 16h by 22 deep. If some how the enclosure be built on top the bump I can go to 34 to 35 on the first measurement and drop the height to 15 and fire the sub up and port forward. Sub calls for 3.5cu ft and tuning @35hz
 

any help will be appreciated
