Product ok, delivery in 12 days.
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.
muy buena calidad compre todo el conjunto superior, twitter, medios, coaxiales y agudos, una calidad espectacular ahora terminare con los suvwoofer... los rercomiendo
un pack impresionante y ademas lo he conseguido a un precio espectacular ademas el envío es muy rápido y perfectamente embalado
Compact and powerful active cooled amp there a remote knob included in the package that show the voltage and etc
Love it. It show when a fuse is blown
Good fit on A4 b6 2004
Hammer Woofer 👍 jeden Euro wert
Great Product, Great Price
Very good experience purchasing several car audio installation products through Masori: Zeus AluButyl 140dB, the Montagehebelset Keile 3-piece soft trim removal tool set, and the 10–100 mm² M8 ring terminal set.
Shipping was fast and everything arrived well packaged with no issues. Regarding the products, the AluButyl provides very good sound deadening performance, with solid material that is easy to work with, ideal for doors and areas where vibration reduction is required.
The trim removal tool set is very useful for disassembling interior panels without damaging plastics or clips, especially in delicate areas, while the M8 ring terminals are of very good quality, offering solid contact and a robust finish, ideal for safe and professional power installations.
Overall, very satisfied with the purchase. High-quality materials suitable for professional-level car audio builds or well-finished personal projects, and a highly recommended store.
