Clutch makes noise when stereo is on

That sounds quite strange.Clutch makes noise while stereo is on? The only thing I can think of that would even remotely affect the clutch operation would be a loose wire hanging down underneath.What about when the ignition is in ACC mode? Push the clutch in and see if you hear a noise.Also,turn the key to ON but dont start it,now push the clutch and see if you hear a noise.Check underneath and make sure there isn't a bare wire brushing against the metal portion of the clutch assembly.This is the only thing I could think of that would cause this.A bare wire that becomes hot when the stereo is on and creates a scraping noise when it brushes against metal (which would be ground).The scraping could be sparking noise from the wire.
