2015 Silverado stereo problems

[Brodycason]

Need help!!

im trying to add an amp to my door speakers . Will not be adding subs at the moment. I tried booking up the line output converter and I guess I did something wrong. And now speakers are acting crazy only 1 on passenger size will work. Sometimes the back comes on then shuts off. I had heard a loud pop from somewhere in dash and that’s whenever everything started messing up. 2015 Silverado double cab. Non Bose system. None of my speakers are blown either. Even when I disconnect the speakers and put them back on. All it does is make static sounds. No idea what could have blown or anything. Any help would be appreciated!!!!  And when I try and turn the radio all the way up the speakers that do work will shut off

Idk what's messed up, but here is the manual. I would reach out to coastal audio services in Canada and see what they think.

Speaker wires? It's the same. Iirc it is the grey connector on the far left when you pull the radio screen.

Hi, I'm looking for the breakdown of the plug for the HVAC controls under the radio display.  I have a 2015 Silverado 2500HD 6.6 High Country.  I have 9 volts on one of the wires.  I just wonder if it's supposed to be that way since everywhere else there is supposed to be power has 12V. This was the closest topic to what I'm looking for. It's the wire I'm pointing to.  It's grey or green (I can't tell) with a yellow stripe.  It's the one next to the black ground wire in the corner.  Thank you to whoever knows.

Sorry I don't have that info. I would start a thread asking for help with that. I'm sure it would get more replies in a timely manner.
