Ok heres the specs on my box I have in my car now and it's a tight fit I need to squeeze these 15's in my trunk I have no clue on box building and I would prefer a ported box around 32 hz if possible but if I have to use a sealed box I guess thats what I will be stuck with. If someone can help me out asap that would be great the subs are on there way and I wanted the box to be ready.
Width: 32"
Height: 13.5"
Depth: 19.25"
I could go 2 inches bigger from these specs
