2013 Crosstour Subwoofer Issue
I have a 2013 Crosstour and the subwoofer puts out noise, but I notice that when I adjust the subwoofer output a +4 setting was no different than a +6 setting in sound.
Sometimes I will have a radio setting glitch where it will readback my subwoofer is +10. Other times the max setting is only +6. Not sure why I getting a different readback setting. I usually have it set at +4.
Is there any quick fix to this issue that won't involve money (so far dealership says I have to pay a diagnostic fee of like $180). I managed to get a picture of the radio setting glitch.
