I have a 2003 Ford Focus and have just finished installing it using this diagram but now i am having problems. When i turn on the radio and insert a cd it plays fine but as soon as i start moving the car the cd skips and the sound stops. This also happens when I use my ipod with the line out on the stereo. This never happened before in my 94 Saturn SL2. Did I possibly confuse the 12v wires or something? anyone?

I have my 2003 ford focus svt subwoofer amp and I need the pin out of the connector. Obviously not the one that connects to the speaker but rather the audio/power input side. Thanks!!
