I finally think I have figured out how to save space in my Xcab and get 2 12" speakers in there. What if I were to build a cab, that had the speakers facing down that pretty much followed the contour of the floor of the Xcab portion? That way I could set my toolbox/ crap on top of it and not worry about the tools being stolen from a bed mounted box. So, how much sound would be hampered if the subs were facing the floor about 1" from the grills? If I put the ports facing upward, would that help my sound? Thanks!
