I just took my truck in for an oil change at 7400 km’s And had them check into the squeak I have now in my 2019 AT4. It’s very annoying and embarrassing for a brand new truck. GM says it’s the leaf springs and there is a fix for it. Some kind of spacer and new u bolts that they ordered for me. Will update once it’s been fixed.
Can you confirm how you tied into Bose system for signal to your amp? Sorry if you already explained. I ordered LC2i module and thinking to get signal from front door speaker wires in wire harness by passenger side front?
Any tips on how you connected the LC2i with your Bose stereo baldor18? I have 2019 AT4 with Bose and a sub and amp out of my old gmc and want to get installed.
