I went thru the settings and also read the manual and was wondering which settings in the audio menu are good to use and which should I avoid? I noticed when I shut off “listening position” I get a louder noise but don’t know what to do with the rest. There is a picture attached I am trying to get the most clarity and loud as possible without distortion. Have factory bose in my 2003 hummer h2 Thank you!! Here is the link for what my head unit has for audio options https://imgur.com/a/DWAXVEW
