What Color Wires Connect On My Kenwood I'm Trying To Hook A Kenwood KSC-WD250 Subw. To My Car. A Blue/white Wire Goes To The Power Control Terminal?

I'm trying to hook a Kenwood KSC-WD250 subw. to my car. A blue/white wire goes to the power control terminal? - what color wires connect on my kenwood

Where the cable is in my CD Player? It has a blue wire and white, and my CD player ... so simple, just connect the two? But I need to be sure. Basically I'm wondering what thread color on a "Sony" CD is the terminal power control. Help? Please?
