Hi All

i have a 2009 A3 Convertible and i am experiencing issues with the stereo. it have the Sat Nav and glove box multi changer

everything worked fine then some idiot ran into the side of my wife contact was on the front off wing (damage all repaired now)

after getting the car back the sound will now just go randomly go off the panel on the Stereo looks like everything working but no sound, i bought a like for like unit replaced it no change :( so i then bought one of the android systems that looks like original and slots straight in, but again this will do the same thing some times it works for days other times will go off come back on after a few minutes other times wont come back on until next day, if the car stands for a while it will always come on ??

so after replacing stereo im assuming it the amp that is at fault but i cant seem to locate it i have looked behind the rear wheel arch carpet and under the rear parcel shelf but nothing there ??? any one know where i can find it before o spend hours rewiring the speakers 

Thanks Dave 

Hi Dave...welcome to the Forum

It certainly sounds like the amplifier failing intermittently.

This is the location for the A4 cab amplifier....maybe similar and behind some plastics ?

Let us know where you do eventually find it
