JacobPitts Posted December 20, 2019 Report Share Posted December 20, 2019 Im building a box for 2 sundown x-12s on a sundown 4000d and was wondering if anyone can help me make sure it will work. The sealed portion is around 2.6 cu ft and the ported is around 6 cu ft. The port is 9x9 and 3" inside and 3" outside. http://s1378.photobucket.com/user/Jacobpitts1818/media/4th order blowthrough_zpspvrnh5vu.png.html?sort=3&o=0 https://imgur.com/5FtIWLk Link to comment Share on other sites More sharing options...
