C4 Soundproofing Idea....
How about a noise cancelling microphone that plugs into Bose system.. Every sound in the car gets knocked out by the stereo.
I know it sounds nuts but there is something here....Bose makes those headphones that cancell outside noise...

i think the only way to do that is to play an identical frequency.. but 180' out of phase.. at least thats what i read.
Ok. Who is going to build it?

There are lots of complicated issues with it such as where to place the microphone. If inside the car, you would never hear the stereo (perhaps a good thing with the bose), assuming it worked perfectly you would not hear police cars, fire trucks and anything else you might need to hear.
Also, each component in the system would introduce some error, the more components there are, the more this gets compounded the poorer the overall effect of the system.
If you try out the phones, they cut down a lot of the harsh noise, but don't acutally cancel it completely. Still pretty good though.
