Does anyone know which wire is the remote turn on? I have a 1990 MB 350SDL, and I can't play cds on the unit without figuring which is the remote turn on lead from the factory amp installed in the car... I also hooked up the headunit's harness speaker outputs to the amplifier's leads which only came out to be red, blue, and yellow and white together... It makes a static noise when volume is all the way down... Please Help. Thanks~!
