The front door speakers in the 2001 Silverado 1500 HD Crew Cab measure 6 3/4 inches. The rear side panel speakers measure 4 inches by 6 inches.
No if its a crew cab they are the same as the fronts. Which is 6 3/4 speakers. You can buy 6 3/4 speakers which are not too common or you can buy adapters that will make the more common 6 1/2 fit.
The speakers in a 2007 Chevy crew cab are around six and three-quarters inches. However, if replacing the speakers, an adapter plate will be needed no matter what size is used.
