It has 4x6" speakers.
My 1996 Silverado Ext. Cab has 6.5" in the door panels as well as 4x6" in thee rear pillers..
They are 6 1/2 inch in the front door panels. If its an extended cab the rears are 4 x 6 inch. Let me tell you from experience replacing the rear speakers in a 97 extended cab is a pain, but can be done. Be cafeful not to break the panel clips then your panels will vibrate when the speakers are turned up.
Front Door Speakers are 6-1/2"
