Forestier Posted May 22, 2021 Share Posted May 22, 2021 I have spent a day trying to find this information on the web. Where do Audi put the amplifier for the radio in the B6 Cabriolet? It is a non Bose 2003 A4 B6 Cabrio. (N.B. It is the actual radio speaker amplifier, NOT the antenna amps in the boot lid) I have a parasitic drain in the radio circuit, Fuse 39. I pulled the radio head unit and the circuit still shows the drain so I now want to check the amplifier. I hope someone has done this and has the information on location. HELP please!

Forestier Posted May 23, 2021 Author Share Posted May 23, 2021 Found it! Thanks for the information, especially the you tube video. Amp is a Blaupunct, (knew it wasn’t Bose). Now I have the part number! If disconnecting the amplifier makes the current drain dissapear, then I will source a second hand item. Can’t check that until tomorrow as I blew the fuse in my multi meter. Thanks again. Quote Link to comment Share on other sites More sharing options...
