No sound on chrisler voyager 2006
 

Hi, I bought a Chrysler Voyager in 2006. There was no radio in it, when I bought a factory radio and installed it, I noticed that there was no sound, then I bought another sat navi rb3 so I didn't have any sound with it either. I read a lot on the forum about the amplifier, I found it behind the speaker, infinity 05091006AD, I bought the same amplifier on the junkyard and put in, on my surprise no sound again. I checked the cables and every pin on the connector is good everything works. I have ground, 12v+ have 2 canals from radio to amplifier. And wt/vt wire is good, why my amplifier not power on?
