Did you ever correct this issue?
I’ve been trying to figure this out myself. I have a refreshed Silverado and currently have the problem. All Alpine door speakers are hooked up to an Alpine amp, and my kicker sub to its own kicker amp.
My chimes cut off after like 4 seconds of turning the truck on. I’ve read that LLJ had a harness, but they’re not taking orders. And Gen5DIY has an “updated” breakout harness that doesn’t work.
I’m going to try the resonator, hoping it works.
