vos Yes, i have spent a lot of time trying different things and documenting the installation. one key aspect was that i confirmed the audio can be improved by controlling the Harman Kardon equalization via the CANBUS vehicle info app, and the Dudu7 internal amplifier power output via the advanced setting in the dudu7 soundstage (mixed of the two),. I created a detailed installation video series going over the installation process for Subaru Owners North America. and i am currently working on a walk through of the new 3.6 OS features. Search for Subaru Outback Dudu7 installation on youtube ..you would find a series of videos , where i documented the entire installation, you would hear a demo on the sound quality and basic Dudu7 (3.5 Dudu OS) functionality.
