2020 Airstream Sprinter Grand Tour Ext

[Redbone]

The new 2020 Airstream Sprinter Grand Tour Ext does not have a fader option(only balance)for the speakers (Dash, front (2) doors, back area (2). The front dash speaker has most of the sound and cannot handle the bass. Is there a solution?

I too have an AS GT 2020. Noticed the same problem with the bass on the front speaker. To my surprise I found a control box under the passenger seat, the side facing the passenger door. There are a number of adjustment knobs and after some fiddling I was able to lower the bass to make it sound better. Unfortunately there is no balance control.

Did some additional research and the subwoofer under the passenger seat is a JBL Basspro and the manual can be found at the following link:
