Someone help me now please. I just got the cd player installed and I am picking up on feedback noise from me engine. It is a wistling sound that is very loud. I already have a noise supresser on it and a ground wire thing. My friend has this same cd player and his does not make this noise in my truck. I had a pioneer 860mp in my truck and it made the same noise but I put it in 4 different truck it did not make a noise! Does anyone know what this is or how I could fix it?
