alright, i got my box figured out, and if someone can run it and see if it comes out good. these are External #'s
37" Wide
26" Deep
13" High
Ports-(2) 4" x 11"
The sub will be facing up and the ports will be on the back of the box firing into the car, not the back of the trunk. Car is a 240sx Hatchback. So if someone can give me an idea how many cubes that box is internal and what its tuned to with those ports. Thanks
