So I'm going to be getting a new car soon. It will be a 2010 model.(I'm not sure of the exact model yet but most likely a Fusion or Mazda 6.) I want to get subs, speakers, etc. Most cars now have the buttons on the steering wheel that control the stereo and the stereo's look good in the dash so I'd rather not have to tear it up. Will it work or just sound like crap. I'm hoping there's things you can buy to make it work.
