: Those systems cost a mint. I hope you are asking academically. If I recall, they use some sort of signal which for whatever reason negates the sound waves coming from the engine/tranny vibes.
: And this in VERY quiet, high end, very insulated cars. I'm sure someone would be interested in trying it for you, for the tune of $100,000.
: In fact, I think it's impossible to do it in a car like an '02. It only works in the cute cars because they are already almost "silent".
: If you want to try to make it quieter, buy a shitload of Dynamat and layer your floor, firewall, and doors with it. And yer still gonna have a loud car.

I have dynomat installed throughout. It made little difference, but the stereo sounds better. I think it does a better job keeping sound in than keeping it out...if that makes any sense. I kinda like hearing the engine and exhaust.
