What are you gonna do about your dash speakers? specially since that's where the phone and chimes sound comes from. I'm trying to upgrade from BOSE system, all 6 speakers.

Hello, I'm trying to do the same but without the harness LLJ has ridiculous wait times. Did it work? and did it drown the front 2.75" speakers or did it sound good? How come you didn't replace dash speakers as well?

Hello, I'm trying to upgrade my BOSE 7 speaker system, while doing some testing with the left dash speaker. I found out that if OEM speaker is disconnected that channel will loose signal and if reconnected again, it will only play again once I shut the truck completely off and wait a few minutes and then turn it on again, then it will have signal again and play normal. I also tried it with an after market speaker and there was no signal at all. Do the front dash channels have load sensors? How or what can I do if I want to upgrade my front dash speakers? 2024 GMC Sierra Elevation Crew Cab With Bose 7 speaker system 13" Infotainment RPO: UQA Thanks in advance
