ok my port is going to be 8x10 for my MT. I am putting the port in the middle of the box on the top because its going to be firing through my rear deck. Would that be considered a square or a slot port. I figure it will be figured up like a square since one of the port sides will not be a side of the box. And also the bport length calculator on carstereo.com said it needs to be lik 20-30 inches (cant remember exactly) to be tuned to what I want, the problem is the box is only like 17 inches high. What do I do, thanks for anyone who helps
