This whole issue happened months ago so the trunk and components are dry. I had it at the dealer for some other issues hoping they could diagnose this on their computer but apparently not. Instead, they wanted to throw parts at it, which I can do myself.

From what I am reading on GM Part sites the Amp requires some type of special programming. Has anyone tried swapping amps? Is this really true or will this at least confirm for me if it's the amp or the speaker that's blown? Unfortunately, there's not a great path forward here since the amps cost like $400 and the speaker that I am having issues with is the most difficult one to access. The amp is comparatively easy to deal with so it's the easier place to start swapping parts... if it's a useful test without dealer programming!

PM me. I can help you out.
