The road surface makes a huge difference in the noise level, too.

You can improve the noise dramatically (so I am told) by installing Dynamat, which is a viscous sound absorbing material installed on the inside shell under the carpets. This will cost you 100lb and maybe $800 for a professional instal. A better investment than an upgraded sound system by a long shot.

Also, a different set of tires could make a big difference. If getting new tires, look on TireRack for actual test data, as I have found it to be very accurrate. I noticed a big improvement on my Camaro when I switched to Firestone Firehawk tires, much quieter, and they performed exactly as reported.
