The front speakers are 6.5" (round) and the back (in the extended cab doors) are the 4"x6" size.
1988-1999 Chevy and GMC full size the door speakers are six and a half inch on the extended cab the pillar speakers are 4x6 in. Some Silverados also had a small tweeter inside the door.
6.5 front, 4x6 rear
I believe the speaker size is 4 x 6. When you go to sites like crutchfield.com, they usually will show the size of speakers that fit your vehicle. For my 2001 Silverado 1500 extended cab, the 4 x 6 was the size they said would fit my truck.
4x10 located in the lower corner each side of the cab.
