Just an update.
With the issue I had with the sounds here:
Advice/Sanity Check
I had to replace the rear door speakers. The Rockford Fosgate speakers maybe lasted 1.5 years. One of them was totally blown. I rock out at times, but not everyday. I noticed my sounds issues above in maybe July 2021, could of been earlier.
I got Kicker 46CSC674 to replace them. They sound great. I hope they last longer.
