for 2 12's u go 2 to 2.5 cubes each which = 4-5 cubes however L7's like bigger boxes so i would go around 5 cubes but thats just me dont go over 5.25 cubes tho. i really wouldnt go under 4 cubes either

i dont understand where this is going. explain what vehicle you have and the type of space you have to put this thing in.

I can do that for you.

it will be a tad on the small side, seeing as how you have well under 4 cubes gross to play with.
