Rear speaker issue

[enfd197]

I have a 2015 Tahoe LS. I have to turn the fade almost all the way to the rear. Just to hear the rear speakers is this normal?

Does it have front bucket seats. ? If so you may have radio to amp circuit issues or even a bad amp only being that its still under warranty you should just take it to a local dealership and check with them
