There are two pairs of speakers, a pair in the doors and a pair in the rear pillars. The door speakers are 6 1/2". I'm not sure of the rear speaker dimensions, but if you call Crutchfield or look at their site online, you can input your truck details and they will tell you what size the rear ones are.
