I took apart my factory radio and grabbed the colume control out of it because i wanted to use it for a hardware volume control. it's one of those volume controls that you can push in to turn the radio on and off. I did some measurements on it to see where i need to hook up my audio lines, but the damned thing isnt stereo. I am guessing that they did some magic somewhere to make this thing control the volume on all four speakers.

anyway, does anyone know where i can get one of these that is stereo? I only need a left and right since all i have is a 2-ch amp. I want one like the one in my factory radio so i can push in the button to turn on the computer.
