Deafening sound emitted from speakers in vehicle while driving. Events are as follows: Volume stuck on 0 (minimum) changed source from wireless CarPlay Spotify IOS to FM. Popping started. No volume adjustment possible. Source change did not fix. On/off button did not fix. Key cycle with door open did not fix. Several attempts. Audio turns off, but with ignition immediately starts popping. Drove for at least 1 minute to safe spot while the popping/ static continued at max volume. Disconnected negative terminal on battery. The only way to fix the issue. Ears still ringing after two hours.
