JL makes some good stuff. It really depends on what kind of setup you are wanting. You want loud or you want sound good? If you want sound good I wouldn't go all JL. With a $10k budget you could have something pretty nice. I see you are from Prattville. Wish I still lived up that way I would hook you up. Drive down to Montgomery and listen to some stuff. I don't know if he still has a shop but there was a guy named called Byrd that had a shop on the Atlanta highway that knows his stuff pretty good. Also I'm sure you know of CKR. Not the biggest fan of them but they sell quite a bit of product and Jimmy's of course.
Btw can't go wrong with Dynaudio! Shoot me a pm or something and I will see if I can help you figure out what you are wanting to do.
This is my truck I did a while back:
