Im going to be in the process of building a ported box for my four 15inch cvrs that are going to be inside of my ford expedition. My thoughts face four firing up with a slot port down the middle? Or face four up and run two slot ports one at each side of the box that's facing the tailgate? If these ideas are garbage let me know and im open to suggestions. What ever will make them louder....
