For what is still needed today Car Speakers and -radios? Since the early 2000s, the factory-installed radios and speakers are usually sufficient for the average driver. Replacement of the original boxing is therefore to only when these go- broken or offer a priori a bad sound. I was looking for 13cm speakers to be incorporated easily in the new Dacia Duster 2014 / Phase 2 - there are in this model no spacers required, only an adapter for the built Renault plug. Installation takes only a few minutes (assuming a Torx screwdriver is ready), the average output power matches the car stereo "MediaNav". Mind you without additional amplifiers. Against the Dacia-original speaker a clearly audible Qualitätssteigerung- one may wonder about these little boxes, however, do not expect.
