*by M***A on 11 September 2024*

Para ser unos altavoces bastante baratos, la calidad del audio es impresionante. He probado sistemas de audio en coches de alta gama y estos los superan con creces, lo que impresiona es la calidad del audio. Eso sí, le falta un poco de bajos pero en sí me parecen altavoces con un buen equilibrio de sonido. Te viene todo lo necesario para instalarlo menos los adaptadores de cable y sujeción. Asegúrate de seguir las instrucciones. Si lo haces bien no hace falta poner separadores de frecuencia. Estoy encantado con los altavoces y le doy las 5 estrellas porque al fin puedo disfrutar de mi música mientras conduzco superando mis expectativas. Lo recomiendo sin duda.
