Anyone know what speaker size is in my ride?

[Dragonsyph]

I have a 2005 Chevy Tahoe with Bose and no navigation.

My question is what size speaker or tweeter is in the rear pillars?   

 

Also so if I’m replacing front 6.5 door speakers do I buy component speakers that come with teeeters and just replace speaker for speaker and tweeter in front pillars for tweeters?  

Or do I have to do something special? 

 

If anything what are some speakers I can just swap in while using factory amp?

Thanks everyone, thought maybe they were tweeters but being midrange thats pretty cool.
