What Speakers Are In A 2008 Regular Cab Silverado (non Bose)

[Cameronb]

Installed a double din DVD/Nav pioneer head unit, putting in my JL 10w6 and PG x600.1 tomorrow...I am going to buy a component system for the doors (6.5" right??)

 

My question I CAN NOT find is...what speakers are in the rear pillar behind my head? What size? It is driving me insane, I have searched and searched and cannot find anything.

 

Another question I have is, say I buy a 4 channel amp...is that just good for door speakers and tweeters in the front? Or will I need to buy a 4 channel and a 2 channel to hit all the speakers? Tweeter, door and rear?

 

Thanks
