HU: Pioneer DEH-1100MP vs Kenwood KDC-3051R vs Kenwood KDC-4051UR

[dudaionescu]

Doresc sa stiu care din aceste HU sunt OK pentru un sistem neamplificat. Boxele actuale sunt niste Pioneer de 35W RMS, dar ma gandesc sa trec pe un Helix B62C.
Dupa specificatii, diferentele intre cele 2 kenwood ar fi doar partea de USB, insa niste baieti de la o firma care instaleaza des asa ceva imi spun ca 30W RMS are doar modelul cu USB - o fi adevarat?
Pioneer parca are un gain mai bun si l-am gasit la jumatate de pret cat Kenwood cu USB. Nu ma intereseaza USB, sincer, pot merge pe oricare din ele.
Nu stiu cat conteaza acei 8W in plus pentru niste boxe de 35 sau 50 W RMS. Sistemul va sta pe un Peugeot 206, care sta cam prost la capitolul insonorizare usi sau asigurarea unei incinte decente de compresie pentru o boxa...
