well, if anyone has read my toher posts, I have made a few fiberglass boxes that fit inside the spare tire on a xb, possibly xa as well. Well, i made a few more this week end but they take alot of labor and time. WEll i contacted elemental designs about letting them produce and sell them. They would get more research and delvelopment, and more tuning. They would probobaly make to fith the sq10 and the 7KV 6 1.2" sub. if this is something you want, let them know. I know they have a great reputation on the board, and thats why i called them and offered the designto them. I just want to see one of my creations go into production
