Once I bought a new radio, I was quite disappointed by the original speakers. I've been looking for two 13 cm speakers for the front doors and stayed at these hang. Purchase decisive were the many reviews, because I have no idea of loudspeakers. For this reason, this review should be viewed as unprofessional viewing. The installation went smoothly, since the speakers fit exactly into the holes of Originallausprecher. The cable I had to cut and had new terminals installed. The sound convinced. There are in the upper price ranges determined better, but I wanted to use any amplifier or the like. Since I had not exchanged the speakers in the rear doors, I had to balance the volume with faders. It was found that this sound was extremely poor, probably because they have different performance. I decided then to buy two more speakers for the rear doors. Once I would have failed almost at the window crank, I had no further problems after removing the cover.
The sound is now front and rear super. Striking is, in my view, that the bass and treble are better represented, without buzzes.
