wiring problem! check wire connection form radio to speaker,if ok, check speaker coil connection, speaker coil may be loosed.
they dont ship stock with rear speakers.
ive had the same problem. my rear speakers are heat senritive. they only work when the sun is shinning down. dont understand why this happens tho.
the rear speakers are 61/4 inch I just dont know what the center speaker size is
The rear speakers are the same size of the front. 6.75" but 6.5" will work also
im afraid this is not a question, not even slightly.
no
According to http://www.installdr.com/Harnesses/GM-Wiring.pdf the connector for the rear speakers is separate from the front speakers. If the connector for the rear speakers is loose or disconnected, the rear speakers would not work while the front ones will. The amp in the head unit (dashboard radio) powers the front door speakers. The rear door speakers and roof (pillar) speakers in the rear are powered by a second amp under the drivers seat. Either this amp is bad or is not hooked up.
check to make sure the wires are good and if the speakers are good
grounded wire im guessing? make sure all the connections on speakers arnet touching the metal of your car, tey may be grounded causing no sound
some do have rear speakers but you will have to check it
You have to go in from the trunk and work upside down.
You either have accidentally Disconnected the Wires to the rear speaks or you have the Fade on the radio set to the front.
