Speakers give a blob or a bang sound
For a 2020 use the warranty.
Ask dealership to check speakers, visual inspection. This can be caused by speaker material coming apart, like if it got wet. Speaker fasteners getting loose another possibility. Try another set of speakers, if same problem, most likely the stereo unit has a fault. In any event, don’t attempt any diy’er repairs if this remains under warranty.
Good luck with dealer. Back in 70s New Plymouth radio back to dealer and electronic shop three times with no resolution. Fixed the cold solder joint myself.
