New DAU or Helag, Front to Rear Speaker Fader Swith, OE Mercedes, 900 820 05 51


  • Please see the vehicle applications listing above for confirmation that this item will fit your car.
     
  • This is s NOS or New Old Stock genuine Mercedes part, without the MB packaging.
     
  • I have several of these and some are made by Helag and some by Dau although they look the same.

  • These are for the front to back speaker fader for mono as far as I can tell, and not for stereo.
     
  • The Mercedes part number on these is 900 820 05 51 however I have no specific application information.
     
  • I would assume these were used on the W108, W109, W114 and W115 models.
     
  • The switches have the standard DIN speaker connection fittings.
