wondering, without much digging on my own yet, if there is a 12v switched wire going to the stock sony amp located on the left side of the trunk? I added a lc2i that senses the audio sound, but makes noise after opening the door. I need to run a dedicated 12v switched unit to get rid of this noise. If you could tell me which one it is, I would be eternally grateful. If not, I will be hiding in the trunk for hours with a multimeter. Thanks guys!
