Redbeardoriginal Posted January 12, 2020 Report Share Posted January 12, 2020 Trying to build a box for a Charger trunk. 2- 15” hippoxl. The build sheet they give out does not really match what the cubic ft for ported box should be. The subs require 4.75 cubic ft each, yet in the dual ported box are saying 6.03 cubic ft together? Not sure how that math works out. Any help is appreciated. CAR: 2006 Charger SRT8 SUBS: HIPPOXL 152R Link to comment Share on other sites More sharing options...
