Speaker malfunction

[Acrust96]

Need some help please if you can.

2018 equinox LT. My wife’s car.

About 30 mins ago we were in line for food. I plug my phone up to the apple car play cord so it pops up on display. The screen kinda looked funny like had green spots on it when it’s supposed to be blue. So I unplug my iPhone to make sure the cord is bad and not the head unit. Next thing I know the speakers quit working on her side completely even after moving them in settings. Then they come back but my cut out. Then on the my side speaker on the dash worked. Then they started thumping slowly then stop. The. Speed up in the way home till it sounded like they were gonna blow. Then we shut the car off and it did this still for about 1 min then stopped completly. It’s never acted like this. Nothing in the audio is aftermarket. All factory.

Thanks

Bring it to the dealer and ask them to do a software update on the radio

Someone else had posted this, maybe it will help you.

"Ok....This worked for me....Now I have a lot more sound coming from the rear speakers. It's the phone connecting with it's bluetooth settings, even if your not using a app like pandora ect....Your phone takes over the system. By turning on " Disable Absolute Volume" in the phone settings I was able to get a lot of sound out of the speakers. I was amazed. Still not as loud as the front but what a difference. I can now send some adjustment to the rear to even out the sound. Hope it works for you. If you have an Android phone you'll have to open up "Developer options". Search the internet a million post on how to do it. Apple I don't know about"
