Why would you want to change the speakers out. Are they broken? The Bose systems in these cars are very high quality and are thought out and tested to give the most accurate sound possible.

Anyway, the dash speakers are for the phones. That leaves 11 speakers for the sound system. The 4 on the rear shelf are woofers. The door speakers are in a plastic enclosure that bolts to the door behind the door panel; 2 speakers in each front door and 1 in each rear door. They have ducts to help enhance the sound. The tweeter is behind the rearview mirror. Probably the only speakers that would be easy to change to an off-brand would be the rear shelf speakers. From what I have seen, it would be hard to mount regular size speakers in the doors.

The amp in in the trunk behind the liner on the drivers side. And there is wiring to the trunk for a cd changer if one is not already installed.
