2016 to 2020 wiring diagram for bose

[Heligrin]

Does anyone have or know of the wiring diagram for the 2016 to 2020 with Bose? I would like to figure out which color is positive for the front dash speakers.

I think you will want to read this thread:

I don't believe anything has changed for the BOSE amplifier colors up to 2020. I used the above link (provided to my installer) for my 2019 GTR no problems.

This may help. I'm in the process of swapping the corner dash speakers to coaxial but ran into an issue. It appears the tweeters are ran in parallel to the door speakers and the dash 3.5 in. speakers are run independently from the Bose amp.
