80adid Hi. I'm planning to buy a DUDU7 A7870 and install it in my 2018 Ford Escape, which has a Sony premium audio system (apparently the same as yours). Could you please let me know if you were able to resolve the issue with proper audio output? I also have a center speaker. The manufacturer provided the following response to a question about the audio: "The sound is output through the front, back, left, and right speakers."
