Sub installation advice for an A3
I'm taking delivery of a 56 plate A3 SE next wednesday and have intentions to fit a sub in the boot asap to give the system the necessary thump. However, my plan has a slight flaw in that it's a company car so I can't change the head unit or make any holes in anything. Does anybody know if it's possible to hook up a sub to the standard 'concert' head unit? Is so, is it possible to run the wires through to the boot without doing any damage? Any advice would be much appreciated.
