Ok so my passenger side speakers work but the driver side front and rear went out at the same time. Any ideas, or experience with that? I don't know if it's a wiring or amp issue.

 

Sorry it is a 97 c230

 

As both the speakers are out, sound like it is most likely wiring issue. I'd pull the door panel and inspect the wiring as it goes through the door jamb. That area is subject to a lot of flexing and it is probably just a broken wire. Good luck!

 

Opened up the driver door, didn't find any inconsistencies with the wiring. Unplugged the driver door speaker and plugged back in. Voila! They all started working! Thanks for the quick response btw

 

Nice when it turns out to be something simple!
