I was bored in class and am thinking about doing a box like this as a temp system in my Jeep for one of my 1012s while im saving on a Mustang. Heres a sketch i made of my idea. Thats a solid panel in front of where the sub is and the opening is about the same width as the port and right in front of it.
when the sub would move out.... it seems like the air would go in a circular motion, back into the other port..... you would need some separation between the two ports...
