i believe all sunfire door speakers are 5 1/4" but with a mounting bracket, it can accommodate a 6 1/2" speaker, depending on the mounting depth.
6X9 in back and 4X6 in front
6x8 for both front and back door panels
In a 2000 chevy Silverado 1500 z71 the front door speakers are 6.5"
6 1/2"
The front door speakers on second generation Neons (2000 and up) are 6.75". These are sometimes called "oversize 6.5"" speakers.
For a 2000 Chevy Silverado Ext Cab 4 dr 4x4 Z71 Front 6.5/6.75 inch speaker remove door panel and then install new speaker reattach panel. Rear 4x6 inch speaker remove rear door panel and install new speaker reattach panel.

Front door = 6-1/2" Rear table = 6" x 9"
take the door panel off to expose speaker
