I am wanting to design a sub box for my pick up, similar in style as this one
I want to make the box as thin as possible so that the rear passengers still have room, so could someone please provide me with:
The OUTER dimensions of the MM1040 Sub or even dimensions of the grill (and no i cannot measure it because i have not yet received the sub as the local distributer doesn't have any in stock and it will take a couple of weeks for it to arrive (Brisbane, Australia))

Hope my writing is clear enough, please feel free to comment :)

p.s. has anyone seen plans like this around? I am designing my own but would like to findout about supports/braces ect...
