I'm going to be building an SPL box for one 12" Orion HCCA. With about 800watts going to it. It will be going in the back of a hatchback 1987 Ford Mustang. I was wondering is it important to have the port on the same face of the box as the sub? Should I have the port firing backwards or towards the front of the car? What frequency should I tune the box to? And how much volume should the box be? Is bigger better? I figure I can get roughly 7 cubes if I fold the back seats down.

 

you should go with an oversized vented box. if you want a size, email me, i can lead you down a path you might be intertested in , good luck

 

7 Cubes is freakin' huge! I think that might be pushing it a hair!

 

i got 32 cubic feet, 7 doesn't seem big at all
