Triticum Agricolam

Hello, I have bee reading around and doing research on building a box for one of my 12’s for my mustang. But when I use your port area calculator it tells me that I need about 46 sq inches. I can’t figure out how to do this with aeroports. The enclosure is going to be firing into the cab. The front baffle that’s gonna fire into the cab has to be angled. So, it would be easier to use aero ports. 2.0 cubes on 1600 rms at 32. I want the box to be firing into the cab and I want to seal the trunk out. Would you have any suggestions. 32 w 14.5 h 5.5 longer on bottom compare to top ex. 10 top and 15.5 bottom. The box can be any depth. I can fit box in from inside if need to be. Sorry for the long question.
