The rear speakers are barely audible no matter how I adjust the sound in my 2022 RWD Wind EV6 (US). The front speakers sound fine, but I’m wondering if the amp is blown. It’s surprising because I got the amp logic update (SA521) two years ago.
My best guess is that the amp may have been blown when they updated the software, but I didn’t notice because I don’t listen to music much, and the front speakers still work fine. Or maybe the amp failed after the update? Could it even be an incorrect software update?
If I take it to the dealer now, what can I expect? Is it an easy fix? Will it be covered under warranty? Will I have to argue to get it fixed? And are there any part shortages I should be aware of?
