theory1230 Posted January 16, 2011 Report Posted January 16, 2011 I would use a 4 inch vent from precision sound products. You can calculate the length at psp.com Quote
cOmpressor Posted January 16, 2011 Report Posted January 16, 2011 You could do like I did and have the port facing one side of the truck. From the top down on the back wall, since you have 4" on top, a 2" wide port x the height of the box x whatever length. Quote
theory1230 Posted January 16, 2011 Report Posted January 16, 2011 I would use two precision ports 4 inch by 10 inch long one on each side of the enclosure firing toward each corner. I like to tune enclosures in regular cab trucks around 37 to 40 hz. I have found that to give the best results. A small truck cab is not large enough to reproduce super low frequency's any way . Make sure to use a sub sonic filter to protect your subs Quote
