[QUOTE="CarAudioNut, post: 178016, member: 547213"] I didn't look at the tutorial that was listed above yet but the cross sectional area of port is how many square inches the opening is. For example you can make a port opening round, square, or slotted it makes no difference as long as the area of the opening is the same and the length is the same. For tunning I usually like to start tuned a little high "IE shorter port" and then take some rolled up construction paper or something like that and put it in the port to make a telescopic section that I can pull out to extend the port or push in to shorten it. I adjust this by ear and when the corect length is found cut a final port of the right leangth and mount it in the box. [/QUOTE]
