I'm eventually going to be doing a complete audio install in my 2010 cc. I'm debating on replacing the head unit or leaving it. I know I am going to be installing new speakers and a sub so I will have to run new speaker wires. My concern is that I will have to cut all wires in dash to accomplish this task. Is there any product that will prevent me from cutting my wiring if I keep my factory head unit? I want to keep my steering wheel controls and have read that the aftermarket adapter is a pain to install. Any ideas?
