My stereo does not currently save subwoofer settings. I turn off the car and turn on the sub settings which go astray. Sub volume is low. Touch any switch setting (switching frequency or volume) and the additional settings will take effect and the desired tone will be returned. Work with Jenson to find a solution. Keep for updates. I will update the date.
