replacing chrysler pacifica radio

Im replacing the radio in my wifes 06 pacifica with my old alpine d-310 so she can have navigation.  I was pointed in the direction of the Peripheral CHYAH05 from an installer friend.  The radio powers on, the amp powers on (I tested connections at the factory amp and pulled same voltages as when pluged into the stock deck).  The amp will not output any sound with the alpine hooked to it. I do get signal back at the amp as I have checked it with a spare speaker.  So it has 12.5 volt in, the switched source is at 12.5, and grounds are the same factory ground.  I also have input going into the amp, my only problem is the amp will not output any sound.  Does anyone have any tips to make this harness work? 

Thanks Aron

noone has seen this problem in the pacifica??  I talked to aamp tech and they say its because it is a different canbus system then all other mopar products.  Does the can bus have anything to do with the factory amp outputing sound?
