Ok so I am thinking about building my own custom sub box for my four door. It is going to hold 2 15s, I am looking to have about 7 cubic feet. But my question is how to caluclate how many the cubic feet I have with my measurements. They are L 38.5in W 44.5 and H 20in. Your help will be very will taken.
