For those who are curious, it's the CD I made for my own personnal use, and I've used it to cure vibrations in a few other cars and loaned it to Hatch for his car and our friend's Lancer. The tracks are:

-Sine sweep, 20khz-20hz
-Bass steps, 40hz-20hz IIRC
-a Bass intensive peice with a good spread and jumps.

These three tracks came off of Kazaa, and I guess Hatch is sending them for free... cause I guess he's a swell guy like that. Imagine it like a real bass test CD for people too lazy to buy a real one.
