Sound Off Arena


    Competing with a car stereo?

      Sure, car stereo competitions are a fun way to show off your system. Competitions bring manufacturers, retailers, and consumers together. Vehicles entered into a competition are judged on all aspects of their sound system, including the installation quality, sound quality, and how loud the system plays (SPL).

    Why would you want to compete?

      Competing allows you to see how good your car sounds to an impartial judge. The feedback from the judges, and also other people in attendance will help improve the quality of your system. It's also a great way to have fun while meeting people that have the same interests.
