Ok, my brother just got 4 new Kicker CVR's, he has a custom box that was made for his explorer, and he had some other 12's in it, but the kickers dont fit in the same hole as the older 12's. my question is what is the easiest way to widen the holes to make the lickers fit. I think a router is the simplest way, but maybe you guys have other tricks, **** CVR's have a wide basket on them, let me know!!
