MihaiFlorin Hi, friend. I just didn't see any posts that talk about sound quality and I'm having problems with that. I have a Chevrolet Aveo/Sonic. year 2012. In addition to the speakers that the car comes with from the factory, several years ago I placed 2 JBL 3-way speakers in the rear. The sound with the S160 is excellent. It has a 3D sound effect that makes it seem like everything sounds like it's live. And a very precise X over for bass. You go from 40hz to 50hz and you notice that subtle difference. And the precision of the bass is excellent. But with Dudu7 I can't achieve the same sound quality. And it seems like I'm listening to poor quality mp3 files. The sound is artificial and inconsistent. I have tried all possible configuration alternatives. Just Eq, adding delay, boost, DTS, etc. But there's no way it sounds good.
