Ok this is going to be my first venture into ported boxes. I've built numerous sealed sub boxes before, but this is the first time I'm going to build a ported box. The measurments are 49.5"L x 16.5H x 20"D. The port area is 16.5"L x 6"H x 14.25"D. According to my caculations the box is tuned to 34hrz. I'm I right or did I screw up somewhere. Oh the box is for three mmats P3.0 12's. Thier going in a '04 Tahoe and I'm planing to have the speakers facing up and the port facing back. Any help will be greatly apreciated.
