So here's my road report for version B. Was in the car driving for 4 hours today, so had a good chance to listen to different types of music. Most of the time the volume was at lower volumes so that the people in the car could talk, but we did have it turned to mid volume for a few songs. I'm really happy with the sound ...most definitely an improvement and worth the money spent. Much fuller sound than before. I didn't find the system sounds (chimes, nav, warnings) too loud when the audio volume was at conversational levels, but it is noticeably louder at higher volumes. It doesn't really bother me and I haven't done anything to try to lower them. I still find the subwoofer to be a bit less powerful than what I was hoping for, but perhaps my expectations were too high. I also have not tried increasing any of the settings on it yet. I'm using the standard DSP settings provided by Hansshow in the github download.
