The boxes serve its purpose fully. Bring a super sound. This it is a 2-way system with crossovers, it leaves the cheaper coaxial version look quite old. They make a clear sound without distortion if you do not overdo it with the volume, which is probably clear. I have installed these boxes in my Golf 2 and have the full standard boxes by Mac Audio Super Audio 13.2 and 16.2 is replaced, both systems with Frequesnweichen. The clear sound and good quality attracts me almost always in the car. But if you want to have a good and clear sound you have to grapple with his radio and you know the highs, mids and lows setting, otherwise all schönene boxes does not help. I highly recommend this product and say, "Very good, I buy again!."
