One by one the speakers stopped working, after I was down to one last speaker and it started to quit every time I hit a bump in the road , I replaced them with a sound system I had from another vehicle I had. However I did need to use half of the plastic speaker that mounts to the door to make them work. How cheap can gm get now I have some noise in all four doors, thank god. I've been a bow tie guy all my life even before I could drive legally, but I'm seriously contemplating going foreign . So much for domestic and the prices are ridiculous anymore. Definitely not worth the money or head ache.
