I am a total newbie to building sub boxes that are to spec, I am in need of or well attempting to desing a new sub box that will give me more room in my trunk + be to spec to what the manufacture says my subs should run for a box size. I plan to build 1 box with separate chambers in it for each sub + each chamber with a port.... Here are the subs I have and the specs to build to.....


Make/Model: Image Dynamics, IDQ12D4

Small:
1.0cuft
freq.: 32hz
Port diem. 3IDX15.5" long

Normal
1.5cuft
freq: 30hz
Port diem: 3IDx14.375"


Now I have these specs but have NO clue on what size box these specs need to be operational.... My current box (not to spec) measures 30X15X14 (Length, Depth Height)....

Like i said I am a total newbie here so any help would be great.....


I think since I am trying to gain space in my car the small setup would be best out of the 2 but like i said i really have no clue....
