I got it all hooked up and it comes on but there is no sound at all

My harness has a blue/white cable that is amp on but i don't think i have any where for that to hook up to so it's not connected to anything

everything else is connected with it mate color but there is no sound from the system

 

it's a 07 nissan altima with bose

Heh, I really have no clue what I'm talking about.

 

You have to double connect the blue/white wire wherever you connected the solid blue wire. In other words, connect the blue wire and blue/white wire to the same spot (wherever that is, I forget). The amp turn on gives power to the audio (I believe?) and it also controls the antenna assuming you have a non-stationary antenna.

 

EDIT

I went ahead and took a look at mine. I have no clue what I'm talking about

 

Connect the blue wire to the blue/white. Here's a picture. The blue/white is the one on the bottom right.
