2015 Toyota Camry Sedan XSE 4dr Sedan (3.5L 6cyl 6A)
JBL Premium Audio System with 10 speakers
 The Toyota Entune JBL Premium Stereo System with the 10- Greenleaf speakers is terrible!  Absolutely no bass whatsoever, no matter what you do to try an achieve it.  When you fade all of the volume to the rear of the car, there is barely any volume.  When you look in the trunk, you will see that Toyota left the passenger side large speaker housing empty.  For a car that stickers for around 35K, you would think you would get a stereo that would be impressive.  This is definitely not the case.  I get so frustrated, I just turn it off.  Toyota needs to fix this for their owners!!
