As already described by other Rezessenten, the horns have a very appealing quality. The power consumption of each horn is 4.7A (measured with a multimeter). "Hüpchen" My original had a consumption of 3A.
As the horn in reality but are slightly larger than it appears on the product image, sufficient space for the installation should be present selbiger. They are not extremely loud, but louder than my old horn. The sound is satisfactory.
