You can do what I did, after replacing my front components , I took the stock front speaker, cut and bent the hole in the rear door and made the 6.5 speaker fit. Mine is powered off the deck and the new fronts have an amplifier to them. Since the stock fronts are plastic cone , they sound good relocated to the rear doors. And they plug right in to the factory plug, so no splicing or replacing wiring is needed when swapping from the front to the rear.
