Ideas for porting through rear deck
So I has this idea in my head I'd like to try. I'll be working with a 12" RF P3. I'd like to build a box that will fit right under the rear deck of my sentra (2006), and have a port tube. Oming from the box into the cabin. I was going to make the box to have the sub firing downwards. I know the reccommended ported size box is 1.79 cubic feet, and a sealed is 1 cubic ft. My question is should I just build a 1 cubic foot box and pipe it up through the deck? Or how to I go about this? This will be my first box build. Any help would be great. Thanks.
I like my subs like my woman. Lean, mean and can take a pounding.
