Review: Muy buen aparato, pequeño y muy potente, cabe en cualquier parte
Review: A transfiguré le son dans ma voiture. Ajouté à un kit éclaté, placé sous le siège conducteur ce caisson se fait discret ne grève en rien l'espace du coffre et offre des basses aussi bonne qu'un ensemble hifi de salon. Les basses sont puissantes, rondes, et dynamiques à la fois, réglables à l'aide d'une télécommande accessible. Un vrai bonheur que ce soit en classique comme en techno.

*by M***S on 20 July 2025*

Nach langem Überlegen habe ich mir diesen Subwoofer gegönnt. Habe den über den High-Input an mein originales Autoradio angeschlossen und ich liebs. Der Woofer passt wunderbar beim Renault Master 3 unter den Fahrersitz. Die Kabel zum anschließen sind auch ausreichend dimensioniert. Beim Renault Master ist es auch einfach, da die Batterie auch unter dem Fahrersitz verbaut ist. Masse kann man sich ganz Easy dann bei der Verschraubung von Fahrersitz holen. Der Klang ist voll und satt. Er rundet den Musikgenuss wirklich gut ab. Würde ich definitiv wieder kaufen.
