Instead of using the RCA's version, yours will have regular wires like all the other ones...so I'll you'll do is just wire the Front & Rear (left & Rigth) Speakers. Just match the Metra 70-7552 same colored speaker wires to the kenwood ddx470 wireharness and you'll be good to go.
Front Left: White+/White Black-
Front Right:

Rear Left:

Rear Right:

If you need me to make an additional diagram I will.
