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?

 

Now i try factory stereo 2005 with cd only and work perfect and asee my becker rb3 is make 2002 but i update him with 2011 maps. Comand on stealing while works but amplifier can’t turn on.

 

does you speakers say infinity on the doors?

 

I didn't Disassemble the door, I don't know what the speakers in the door are like

 

its usually on the outside on the door. take a look in the fuse boox look for a NBS relay see if its there or not. the infinity speaker need that relay turned on inorder to power them up for sound.

 

i don’t have NBS relay, empty, no wire there, my car have amplifier on the back seat right behind the speakers. Today I bought factory stereo with cd made 2005 and finally I hear music!
My question is how to make my becker RB3 to activate amplifier.
