You can fit any 6x9 in the rear that you'd like...... trust me. My Boston Accoustics use huge magnets wrapped with a rubber protector, and they are three ways. The mid and tweet are in the center and extend out about half an inch above the frame of the 6x9 and they still fit with the factory grille. The front door 6" is a different story, and you will have to cut the basket for anything better than a K-Mart special to fit.
