Currently in the works is a new box for my type R's. They will be in a false floor, spare tire well is fiberglassed. I know it is reccomended that both subs do no share air space, but is it ok? Im going to port it somehow as well, but i need like 28 inches or something of port per sub, and i read that a 45 degree angle in the port is ok, but im not sure. So 2 chambers or 1, straight port or curved port.
