Ok this is what I am thinking on building now. After showing the the box looking like a home theater box you guys sparked my thoughts and idea's so this is what I came up with. I am only concerned with the port size since I have not done ported boxes since I was like 16 soooo. I will get it figured out let me know what you think please. Try to think of both these boxes in the trunk. So when you fold down the seats you see the plexi ect ect ect.
