Speakers crackling and popping

[RangerWeaver]

I have a 2011 ram 1500 SLT. In 2021 I replaced the stock head unit with an aftermarket unit with navigation and backup camera from Crutchfield as well as the wiring adapter. The head unit worked perfectly with great sound quality until earlier this year. Around the middle of February I started getting a crackling/popping sound from the front door speakers that only starts after about 30 minutes of driving with music playing and does not go away again until the truck sits for at least an hour.
I think it might be a short in the wiring or a grounding issue. Does anyone have a radio wiring diagram for the 2011 rams?

Finally took the time to find the cause of the issue.

The speaker had shorted internally and burned through the fabric backing.
