Yes, wire into the radio loom which is pretty accessible. I agree though re effort. Tbh it took me so long to run the 12v from the battery, when i ran into issues when wiring the unit in, I had to call it quits.

You are right re the factory amp if it exists? I am not so certain that the basic set up has an amp at all? Iirc from taking my standard unit out it only had two wire clusters but no cd changer / amp input. My XC60 unit does have this i think, and that is a basic sound system. It does have nav though so could be why?

I will definitely be revisiting the amp over the next few weeks if i get the weather..
