Randy, thanks for the great work!
I was able to connect the blue/white wire from the amp to the switched 12v line and get music! My Son is very happy now.

Not sure what all the other extra wires are for but since he's happy with it...off he went back to school.

Thanks for working with me on it!

Paul
