amigos les cuento me compre una radio china para mi troncomovil , es lo que buscaba muy multimedia , pero la pregunta es , que parlantes le instalo , por lo que leì tan solo me conformo con unos coaxiales si es posible de 3 o 4 vias , mis parlantes de fabrica son de 16,5 cms y es lo que quiero mantener no quiero nada de instalar otro sistema , sino lo mejor dentro de esos modelos coaxiales , les doy la caracteristicas de la radio.
otra pregunta , la radio me da la posibilidad de 4 parlantes
¿ es recomendable??
no quiero hacer mas agujeros en el auto , con 2 me basta , pero al colocar 4 ? podria mejorar el sistema de audio envolvente o tan solo aumento el sonido???
