I checked both of my rear doors and both of them dont make a sound lol

Edit: i tried looking through it with my flashlight and i dont see any speakers but i just wanna make sure

 

From what I know, you only have speakers there if you DONT have Mark Levinson. If you have ML then your rear door mids are move to the back by your subwoofer. Where as the non ML cars don't have the 2 rear deck lid speakers. I believe the they did this to give off an impression of true surround sound. But, don't worry if you have ML your good lol, I remember wondering the same thing too not that long ago

Happy new year!!

 

i have the ML so thank god! Thanks!
Happy new year!
