I have a farenheit dvd player hooked up to my alpine cda-9827 through and aux-input and also to my lcd tv screen. At first my dvd player was plugged into my cigarrette lighter until a local audiophile told me this is the noisiest place in the car, then i tried hooking it directly to the battery and grounding it the the car body with a self tapping screw. That helped a little bit, but not much so i just tried the last thing i could think of, i spliced the positive and negative wires inline with the positive and negative going into my head unit, this also helped minimally, i also have the power wires hooked up to a 20 amp heavy duty noise filter which helps some. The sound i get is an irritating high pitched whine that increases in frequency with the engine rpms, this sounds is not noticeable when my headlights are off but gets extremely bad when my lights are on making it impossible to watch movies at night, or when it's raining, or when it's cloudy, you get the picture. I even had my alternator tested but it was fine also. I am out of ideas here, any help or suggestions would be greatly appreciated. Thanks in advance!
