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.
The size of the rear speakers in the 1995 Chevrolet Silverado extended cab is 4 inches by 6 inches. General Motors has been manufacturing the Silverado since 1998.
You don't need factory speakers. Just buy the same size speakers and install.
4x6
Front Speaker 6.5 4 Front Tweeter 1 1 Rear Speaker 4X6 2.5
The front speakers are 6.5" (round) and the back (in the extended cab doors) are the 4"x6" size.
18-25 gallons
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.
It has 4x6" speakers.
All the speakers in a 1991 Chevy Silverado should be 4x6 if they are stock.
Generally, a stock silverado will have four speakers; two in the dashboard and two behind the seat.
