hook the speaker wires up to them and turn the volume up.
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 the same size of the front. 6.75" but 6.5" will work also
It could be that the connector wire broke in the rear. It happened to me.
change the flasher
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.
Your speakers prolly broke. I had to replace mine after it was around 8 years old. It just happens. Take the door panels off, and it should only be a few bolts to take out the old speakers, then just cut the wires and splice them back together on your new speakers, set your speakers in the brackets and screw back in. And now you have speakers that work!! Hope that helps!
I have a 2000 olds alero and the signal light only work sometimes, What would cause that?
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.
6 inch. Shallow 6 1/2" speakers will work, as I'm not aware of any 6" after market speakers.
shoud be 6.75 in door 6.5 will work and 4x6 in rear
You don't have to remove it, but just unclip the rear seats so they could fold down. Gives you more room to work. That's what I did when I did my rear speakers in my 01 civic.
