So far, I have only used this CD to fine tune my home stereo system. It was very helpful in adjusting the speaker placement. Many years ago, vinyl records were used to do what this CD does, and I even had one that I used to tune my quadrophonic system! Fine tuning or adjusting stereo systems seems to be a practice of the past, and aids like the AutoSound 2000 CD are hard to find. I guess that is all part of the modern times situation of declining music quality!

The best online store I've had the pleasure of doing buisiness with. Not only are the products great quality at low prices, the staff and the customer care is second to none. I really could not be more impressed.
