A4 B6 CABRIOLET - WHERE HAVE THEY HIDDEN THE RADIO SPEAKER AMPLIFIER?

[Forestier]

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!

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.
