Hahahahahahahahah, man I love you
This is on any nFx board (that I know of). I have it kicking around here somewhere on my nF2, and I know a guy who has it with his nF4. Though he uses a flashy sound card now, even the drivers with that have it.
It's know as an equliser (run spell check), and you can just throw the bass to the max... or like me do it with your speakers and save some audio cycles. I race with max treb, and max bass on my Megaworks. Sounds amazing, and the floor vibrated (Though I was told it can get loud downstairs at times ).
