Avic Z3 rear speakers

[Nanatraci]

Good morning everyone. I have installed a Pioneer AVIC Z3 in my 2013 Chey Silverado 2500hd. I have encountered some issues. My rear speakers are barely putting out any sound, even when i put all sound back there. I have no idea what to do now. Thank you.

I have no idea what to do now.

I know earlier model Silverados were having issues with moisture in the doors. It would corrode connections and break down the integrity of the cones & surrounds. You may want to pull the panel and check that first.
