I am fixing to finish the ordering for my new system. The rear doors on the CC has 6.5" speakers so it is a great place for 6.5 components. Both the front and the rear door speakers will be amped. My question is: should I replace the front 6x9 with another set of 6.5 components or stay with the 6x9? All my research is starting to point me in the directions of components in the front and rear doors.
