First of all: The part has simply best met all my expectations for an active-Bass: It's small, but nevertheless makes absolutely sufficient pressure. Of course, the bass can not compete with expensive and much larger devices that have an external amplifier. But who does not want to bring necessarily to vibrate the disc of neighboring cars, does not need my opinion, more power, because of your own truck the bass is absolutely sufficient. Bring this to vibrate my rear-view mirror on half power.
Or rather said: Brought. Because unfortunately the Sub me is smoked recently. First he began when driving over potholes and other surveys an extremely loud and muffled sound for a few seconds to make, then he finally worked and no longer remained silent.
To be fair, I have to say that I bought used him and he has still done a lot of one thousand kilometers me well! I can not say how long he had been before on German roads so.
Therefore, there is of me now unfortunately "only" 4 stars ... a pity, have never seen a product at Amazon, who had only 5er Reviews. Bin'm very satisfied with the price / performance anyway and maybe buy it to me again. Simply enter still a strong buy recommendation, perhaps my only yes ner Monday-production: P!
