What are the right size for the replacement speakers on a 2000 Chevy Silverado Lt 1500 with the extended cab?
The front speakers are 6.5" (round) and the back (in the extended cab doors) are the 4"x6" size.
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.
Contrary to what people think,A 1994 Extended Cab Chevy Sportside Silverado came with the 5.7-liter 210-hp V8. People think the 350's were putting out more than that but not so. this is taken from a Chevy dealership in TC..... http://www.roncarterchevrolet.com/testdrive-review.aspx?year=1994&make=Chevrolet&model=Silverado
