2002 Non-Bose system

[donmauldin]

I replaced my rear oem subwoofer a few years back in my 2002 Tahoe Non-Bose stereo. Fast forward a few years and the new replacement subwoofer stopped working, so I assumed it was the sub.
I bought a new sub and its not working. So I'm in the process of elimination,, ugh. I removed the cup holders and found the harness beneath and unplugged it. Now all of the wiring diagrams that I have found are different in the harness from the diagram.I'm trying to eliminate the rear audio controls or the rear wiring. Any suggestions?

Thanks in advance!!!

Is the new sub for a 2021? This is the 2021 forum.
