Eingebaut in A-Säule, Klanglich sehr schön, Pegelfest. Bin zufrieden.
Sehr guter Klang, Top Preis und eine schnelle Lieferung.
Hören sich gut an!!! hätte ich nicht gedacht in der Preisklasse, vor allem der Pegel hab sie mit paar Axton Hochtönern verbaut und einem Kicker sub im Kofferraum und paar Rainbow Endstufen sauberer lauter klang bin sehr zufrieden mit dem Produkt. Langzeit noch keine Erfahrung da erst zwei Wochen verbaut
Versterker was goed verpakt, En heb dit beest gelijk getest op volume en klinkt geweldig op mijn subwoofers, Het geluid vervormd niet zelfs op vol volume klinken de bas tonen zuiver, Ben vooral blij dat ik deze versterker gekocht heb. Ik geniet van elke seconde in mijn auto,Ik kon het merk niet van de versterker [gs-audio] maar het is top merk en het is met de hand gemaakt en komt uit Italy is echt goed gemaakt alleen mijn auto heeft het zwaar te verduren alles beweegt, Dus top aankoop gedaan.
