I have a 07 suburban an a local friend of mine designed a box for me an to me its way to huge for the subs, an I feel they are not able to perform to there fullest potential. I really need help my wife is going nuts cause we don't have room for luggage an the fact that I paid for a box that is worthless an not performing.
