What are the factory speaker sizes for a 2009 Ford Expedition?

[Todd_Gearhead]

I’m planning to upgrade the sound system in my 2009 Ford Expedition and want to make sure I get the right speaker sizes. Can anyone confirm the factory speaker sizes for both the front and rear doors? Also, if you've done a speaker swap before, are there any considerations I should be aware of, like depth clearance or compatibility with aftermarket options? Any advice on improving sound quality would be greatly appreciated!
