In the past blue wires were normally a remote wire for amplifiers. I am going to be fitting one myself in a week or so. If you still need this question answering I will comment once fitted as I plan on fitting a sub too.

Advise please. I have a 04 a3 and I've looked into these wiring kits from halfords. Has anyone used one There's a lot of mixed reviews, people complaining aboub not working. I'm not a expert at ICE fitting but I've fitted a few systems in the past. So I'm not to worried about rewiring some of it, but one to know what I'm getting into before I get into it.
