I had my stock Clarion single DIN radio repaired just before Christmas and after reinstall today I have no sound out of the door speakers. The middle speaker and both back speakers are fine. Can't remember if they were working before the radio quit. Is there possibly a separate amp for the door speakers?

 

With a non-Bose setup, there are no amps for the door speakers. And the center speaker feeds from the same source as door speakers. And as you can hear the center speaker working, that means door speakers themselves are bad.

 

Thanks for the reply! I tried to take a look at the center speaker amp to see if the wiring was an issue, but seems like I'd have to take the dash apart to really get to it. I pulled down the glove box, but couldn't see too much. It just seems so unlikely that both speakers would be out. I may pull the radio back out and attach another radio I have to see if the door speakers work.

 

I think It should be under rear console cover - somewhere between the two seats (where your elbow would rest).
