    This review is about a variation of the product

    Excellent for its price! Small size, fits easily everywhere, and with proper adjustment and a decent source, it plays very nicely and clearly!

    This review is about a variation of the product

    With proper installation, proper speakers, and proper adjustment, it works just fine. Installed in a VW POLO 6R (under the passenger seat) with 4 Focal IS 165 VW speakers and a Sony XAV-AX1005DB source. Very good sound quality and volume. It's not for competitions, let's have the right expectations, for €120 it's just fine.
