Did you ever figure this out? Looking to install 2 10” subs and an amp in my 2022 Silverado refresh and was hoping to find some help online. Not looking too promising so far

I’m having the same issue. Want to install a sub in my (non bose) 2023 3500 sierra. I’m looking for the speaker wire colors.
