Their shaking affect is quite impressive when the car isn't moving. However once the car is moving at more that 30mph the slight vibrations from normal driving seem to cancel out the bass shaker affect. Maybe they work better in other cars, but the sports car (stiff) suspension in my Z3 appears to make the bass shakers a poor decision on my part.
