Hello my friends thank you so much for your time to reply this post, well i use the diagram with the manuls owners comes AV section exactly and the last pages with premium audio , cuz the harness are the same and the colors of the wire too, so in this momment finally i have sound on my speakers the tweeters and the front and rear speakers too, but the bass its not sound anymore, before when i have the factory head unit the bass sounds incredible even with a great vibratiln the rockford fosgate its really amazing but now that i change the head unit for jvc the bass not sounds at all just the speakers, and clarifyng i cut the wire cables factory beacuse i dont have harness so i cut and put in together and isolate with a electrical tape just the manual says color with color exactly that says in the manual, but still no bass at all, and i have a noise that i read in others comments maybe its because i dont connect the shield wire, and there are a few of them, just isolate because in the harness of jvc isnt any wire for this shield, but i read in some web page that ground and shield are different connection, ground its connect to the chassis but shield its connect to other place , and i dont know where to connect this shield wires, .... Thats all for the momment its my first time replacing a stereo head unit , please take me a little patience jejeje thank you so much for your time guys
