I love pretty much everything that has to do with car audio. I am a huge fan and supporter of Doctor Dashboard in Terre Haute, IN. The owner and staff there are great! They sponsor several bass competitions througout the year. A bass competition is where people who have systems in their cars come and hook them up to a meter. The meter reads the sound pressure level (SPL) inside the vehicle. There are several different ways that the competition works. The most used method around here is to have more than one run at 30 seconds per run. To get a free Doctor Dashboard sticker, click here, print the page, and take it to the Dashboard store near you. There are stores in Terre Haute and Evansville, IN and Puducah and Owensboro, KY.
