My model is 2021 Hyundai Palisade. First two days the rear speakers were working fine but these days I cannot hear a single sound from rear speakers which is second row. Front speakers are working perfectly fine but the rear speakers are not making any noise. Quiet mode is off and I now don’t know what to do to fix it. I went to dealership and it worked perfectly fine there but when I arrived back to home, it started to not work again. Help me out please!
