Stereo upgrades

[chris 00416]

I am looking for any information on wiring harness is for a 2020 RST crew cab with a Bose system. I am having a shop do work on my truck and I want to give them as many tools as possible so they don’t cut my wires. If anybody please has information I am looking to add a sub amp and woofers and also a four channel for the highs and mids on the factory head unit. I have not seen on the Internet that they make an aftermarket head unit I am not trying to lose my functions to the truck. I am also looking for any information on wire diagrams for the doors and the tailgate. I do not want to add an aftermarket alarm because i don’t want to use a different key pad! I want my Chevy key fab! I want shock, tilt, glass break. I have seen on the InternetThat you can add these sensors to the factory alarm. Just by tapping into the doors of the truck. Does anybody have information on this also.

Use a LOC. Connects the factory amp and the aftermarket amp. No need to cut wires.
