I’m happy to help further over the phone at https://www.6ya.com/expert/david_6df67de3b14de867

Your ground wire is going to be black. Your normal wire colors are violet and violet/black, green and green/black, white and white/black, last but not least you have grey and grey/black. Those are your speaker wires. Solid blue is usually to power your antenna, and blue/white is for your amp turn on lead. Those two wires are approximately .5mV of power, and you can actually use either one to turn an amp on. Speakers: normally your solid color is positive, while the black stripe is your negative. As for which one goes to which speaker, left front is white, right front is gray, left rear is green, and right rear is violet. Hope this helps.
