Just installed a JVC kd-g510 head unit and I am getting a small static noise during any playback. It is not there when the unit is on but nothing is playing and I am not sure but it seems to only happen during sligtly bass output. Any idea what this could be and what the fix would be? I know its not the speakers (infinity reference 6002i) since I used them with my old head unit and they sounded great.
