JBL door speakers not working?

I have the 2012 entune with nav JBL system. So I was listening to my radio the other day and noticed with a song that something sounded funny. I started playing with the fader and found out both of my front door speakers were not putting out any sound what so ever. The tweeters sounded great so I had no idea when it happened. The truck has 29000 on it so im bringing it to toyota for the bumper to bumper warranty but has this happened to anyone else?

 

My drivers side speakers are making a sound like something is loose in the door. I need to take mine to the dealership as well.

 

Thankfully this is in the marketplace section.

 

I'm not the OP. I just chimed in because of the subject.
