Audio Systems: Car audio sound quality tracks, sound offs, test cds

Question
Hi! I just upgraded my car audio and I was wondering which albums/tracks should i get to test the quality.

Answer
Hi TJ
you can buy test CDs for sound offs but without test equipment as used at such events,,, useless.
Just get what grabs ya and if you like the sound and it doesn't vibrate, pop, cut out or crackle when you crank it up, you have done better than most!
