Car audio shows are one of the most exciting things in the car audio hobby. They bring together people of all backgrounds that share a common love for car audio and competition. There are four major car audio show competition organizations. If you think competing is right for you, check them out below. Not all car audio show organizations are available in all areas.

IASCA - The oldest car audio competition organization and also the largest. IASCA has traditionally been associated with sound quality competitions but has more recently added the idBL, an SPL (boom car) category. Their sound quality segment, SQ, has seven categories and only two power classes, 1-600 watts and 601+ watts.

USACi - Once the new kid on the block, USACi has become a major player in the sound off scene. USACi also has two competition formats, SQ (sound quality, basic and advanced categories) and SPL (boom car). USAC was started with the idea of bringing fun back into car audio competitions. There are two power classes in each SQ division (0-600, 600+) and several in the SPL competitions.

dB Drag Racing - Started and led by veteran competitor and soundoff legend Wayne Harris, dB Drag Racing is just what the name implies. Competitors boomin side by side for the title of loudest vehicle. The measurements are displayed on a large drag racing type "tree" and are very exciting to watch. dB Drag is all about SPL. If you want to be a boomer than you need to look into dB Drag Racing. Competitors are classified by the number of woofers in their system and the extent to which their vehicle has been modified.

MECA - MECA classes its SQ competitors by the extent of vehicle modification. Competitors are classed as either Amateur, Street, Modified, Modex or Extreme. MECA also offers SPL classes in similar categories.
