wires

Okay so I have a 2001 beetle. Were trying to install a daul xdma450 in place without a wire harness. We can't find the remote wire to hook up my subs. So can someone tell me the wire colors and what they are? (:

Decided to do a tune up on the car. I went to autozone and got some plugs. They said they didn't have any plug wires. there computer wasn't even showing a part number. I tried 2 other auto parts stores and the same thing. No one offers a aftermarket replacement yet?
