I'm wondering if this applies to all of you with JBL with navi system. My system's fader shows that it is set right in the middle between the front and back but it seems the front gets most of the sound and the back gets only a little until I move the cursor back a couple of notches. My parents have the same 2010 JBL with navi and theirs is the same thing. Is this normal or am I going crazy? If it is normal, why?
I had a 2010 and now a 2013 and I experience the same behavior as you depict here. I assumed it was "normal".
Ditto 2016 v w/nav but no JBL. I have the fader moved 3 4 or 5 notches to the rear to improve sound quality to my ears.
