Has anyone had problems with the upper door speakers? I getting some bass feedback like a speaker is bad in my left door. Just wondering if they're not good quality or not?

Have not had a great deal of problems with these speakers-from the service department view. If you have a Shaker system-the speakers are better quality than the base system. The base are just a paper type cone with a whizzer cone for highs, the Shaker has a plate style two way design.
If you need to, you may want to consider replacing them with an aftermarket three way 5x8" speaker.
