You do want to be REALLY REALLY CAREFUL when messing with the B pillar in modern cars. A sensor for the side airbags is usually in there somewhere. The seat belts, also, are explosive pretensioner types that you need to deal with gently. It's worth buying the service manual ($400 for the 2017 Bolt from Helm; not sure about other years) and studying up on the deactivation/reactivation procedures. It might be more than just disconnecting the 12V battery.

2023 EUV LT (non-Bose) - wiring through the doors?
I recently picked up my 2023 EUV LT -- it does not have Bose sound system and I would like to do a full upgrade of the audio components. Since replacing the head unit is out of the question, I'm planning to tap into the speaker wires and run speaker wire input to a new amp (that accepts speaker wire signal as input) that I will put in the trunk. Then obviously I'll need to run speaker wire back from the amp to the upgraded speakers in the doors.
I took the door panel and trim off today, which was fairly straightforward. However, getting wiring through the door panel seems to be a challenge. I searched the forums and see lots of people who have tapped off the Bose system already in the trunk or simply replaced the factory speakers (using factory wiring). But has anyone successfully run wiring through the door? I'll attach a picture of the rear driver's side door that shows where the wiring would need to go through.
Another alternative I'm considering is just figuring out the wiring before it goes into the door panels -- splicing off the speaker wire before it goes into the door panel and utilizing the factory wiring through the door. This is probably what I'll do if getting wiring through the door panel is a major pain, as I really don't want to mess with the rubber grommets and risk allowing water/dirt in.
Any input would be appreciated!
