How many speakers and what size are they?
 

I plan on updating the stereo system in my car. Has anyone verified if the front Bose speaker assembly is the same between the PF cars and the FL cars? I found PF front door speaker assembly but I want to make sure I can use them before I buy them. I plan on modifying them to fit in 5 1/4" speakers.

Does the rear doors have speakers? Or is the only rear speakers are on the rear shelve? What size are those?
