I used that trick to mount a 200watt amp and 12inch sub to the back of my computer chair. I plugged in a 5.1 system and used the amp and sub for the ".1". In Need for Speed 2 Underground my chair rumbles as if I were actually in the car. When the bad guys in any given FPS shoot me, i get jolted. I can feel the kickbacks from the guns. Very highly recommended hack for you gamers.
