jft32 Posted May 12, 2010 Report Share Posted May 12, 2010 Need help with box specs and design for an 18btl. It will be going into a 2002 jeep grand cherokee. The space that I have available is 40x23x16 (w,d,h). I want the box to be tuned to @30hz. Sub will be powered by a planet audio bb2400.1 I would like the sub to be facing up with port firing back. Any input that you guys can give me would be greatly appreciated. Link to comment Share on other sites More sharing options...
