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.

: Has anyone ever investigated the free-standing (as opposed to headphones) active noise cancellation systems to install in a vehicle? I've noticed that the headphone based systems have dropped in price to about $60. I also know that there are companies that specialize in designing a system for your airplane, but presume they are pretty expensive being custom and airplane related. The Infinity Q-45 and J's had a noise cancellation system as an option a few years ago. I bet it would do wonders to drown out my infernal ANSA. Any experiences or suggestions?
