Sorry if this has been covered but a search didn't really bring me to the answer. I have a 2012 Audi A3 8P Sportback in SE trim. I'm looking to install a parrot-type system which requires a SOT lead. It is fitted with a double-din Concert III and as far as I know has no BOSE system (nothing on door cards/speaker covers). How would I identify if the car is amplified, or does anyone know?
As far as I can see I require a quadlock adapter (being ~2006 onwards), and I have narrowed down to SOT-1103 lead. If anyone could confirm it would be a huge help!
