Review: Sehr gute Lautsprecher mit einem wunderbaren Klang. Der Einbau beider Lautsprecher hat mich 15 Minuten gekostet, also super schnell, und einfach. Das Produkt kam sehr gut verpackt und sicher an. Seit ich die Lautsprecher verbaut habe ist das Fahrerlebnis direkt gestiegen. Eine absolute Empfehlung besonders für den Preis.
Review: Perfect, goed geluid, verwacht geen wonderen, het zijn maar 10cm speakers alleen zijn ze stukken beter dan origineel wat in een Peugeot 107 zitten
