If you run across a 2019 Toyota 4Runner with intermittent no sound from the radio or a code in the amp for shorted speaker B15C3 output or works fine on low volume then when you turn the sound up, it shuts down, check the right/left front Dash speaker for it touching metal.

Thanks for this info. My wife’s 4Runner has intermittent sound. Was going to start checking resistance following Mitchell’s flow chart. Will go straight to this first and see what I’m able to find.
