yesterday my wiring harness and dash kit arrived, got everything connected and nothing will come out of my speakers, has any one else had this problem and found a remedy? on the factory audi deck there is the schematic that shows what pins are for what i noticed that there are several more outputs than my new deck has, do i need to just double tap into those lines? and then the antenna adapter that came with the wiring harness has a blue 12v line coming off of it, does that tap into my constant power supply or the running power supply, someone has to know what what im missing. id appreciate any help i can get

...first, we need more info if your car had the Bose system or not.

The Blue wire for the antenna adapter is a turn on lead for the built in to the car antenna amplifiers. You connect that to the 12volt antenna output lead from the aftermarket radio. Without that, you will have reception issues.
