I have a 2013 f150 suoercrew and going to buy the foxacoustocs single ten box. This box is ported tuned to 35hz, 1.25 cubic feet, and has a max depth of 6.75. Trying to decide between an SA10 or an SD2 10 from sundown. Is 6.75enough depth for the SA10? I've searched for over an hour and can't find any builds where someone discusses a setup like this
