Edmunds just did an article on the "Top 10 Sound Systems in Cars Under $30,000." The Bose system in our Altimas placed 2nd!

Check it out:2. 2002 Nissan Altima (Bose)
We were pretty amazed when we finally got to listen to this system, and yet not totally surprised. The week before this car came into our offices, we were walking down the street and heard a loud thumping noise. Looking up, we found a 20-something commuter in a sparkling new Altima bobbing his head in time to the music. We couldn't agree more. Considering the price of this vehicle, the stereo is a real steal. Be sure to order the optional Bose system (MSRP $899), which comes standard on higher-priced trim levels but costs extra on the base models. The system comes with a six-disc in-dash CD changer, eight speakers and 100 watts of power that sounds like double that. (Fans of our long-term program will note that we've had some trouble with our long-term Nissan Altima's stereo quality, however, the stereos of all other Altimas we've tested have been great. This leads us to believe that our long-term vehicle's situation is an anomaly.)
