Saw this on the youtube and now I want to do similar to all of my cars....

Anyone (cough, cough, Sparkie) have any ideas on how to do it? The guy that made the video put together a kickstarter for things that plug into the car that has all of the crap including a speaker inside. I want to do it where it still looks stock and I can plug the chime speaker back in and use it without being annoyed.


P.S. Damn this forum is a ghost town now!
