[QUOTE="kickerlivinloud, post: 440827, member: 552730"] Ok to cut the cost of my system I am building my enclosure completely my self. I have it custom designed to my trunk so it is really hard to explain what it looks like. B/4 any type of dissplacement I have come up with about 6 cubs of space. I am hopeing that with the diss. of the wood, driver, and port it will be closer to 5 cubs. My main problem now is trying to figure out how much port area I need. Using the caculators over at loudspeakers101 I have gotten this info... [URL="http://www.loudspeakers101.com/VentCal1.htm"]http://www.loudspeakers101.com/VentCal1.htm[/URL] Minimum Diameter = 15.05 inches Minimum Area = 177.98 inches Length of a side for a square vent = 13.34 inches This is all for an 15" sub with 38mm Xmax tuned at 45Hz. What I want to do is either make a plug or and extention to lower the freq. to 28Hz for daily driving. Should I use a 13"X13" inch port or should I make it smaller. I am totaly new to the actual install part of car audio so bear with me. If so, how can I make a plug/extentsion to reach the 28Hz???? I am open to ideas... Your input is appreceated... Jon [/QUOTE]
