SQL (Sound Quality League) focuses on high performance musical systems: Sound Quality (SQ and SQ2), custom installs, and RTA Freq Out contests. Vehicles are classified by audio system complexity of design. The AudioControl SA-3055 is the official 3X points contest RTA Freq Out meter. For 3X points Sound Quality contests, 3 Judges evaluate the audio system separately, and the scores are averaged to determine the winners in 7 classes. There are 4 Install classes.

SPL (Sound Pressure League) focuses on loud bass Sound reproduction systems with Sound Pressure and Drive-by SPL Parade contests. State and World Champions and USA National Points Champions. Vehicles are grouped according to the "Pressure Class" method which separates the vehicles by complexity of audio system design, combined with the potential of the audio system to make "bass". The "Pressure Class Formula" adds woofer cone surface area with sub amp(s) power. Woofer cone surface area is measured in square inches. For example, a round 12" woofer is 113 sq. inches and a square 12" woofer is 144 sq. inches. Power is determined by fusing X 10. For example, a 30 amp fuse yields 300 watts. The Street, Modified, and Radical X divisions and Drive-by SPL Parade have unfused, or unlimited, classes: S5, M5, X2, and DB5. The Amateur Street division has 3 classes (AS1, AS2, AS3) and is limited to basic audio systems with the SPL test taken with the motor off, sensor placed at the driver's seat headrest, and only music tracks can be used (no tones or sweeps from bass test CD's allowed). The TermLab meter is the official 2X and 3X points contest meter. There are 15 SP (Sound Pressure) classes and 5 Drive-by SPL Parade classes. SP is measured inside the vehicle. Drive-by SPL Parade is measured outside the vehicle, 6' from the passenger side, with heavy-duty bass music tracks, for example: BassMekanik 808 CD released 2009.

Crankinshine "Show & Shine" car/truck/motorcycle contests. Judging based on cleanliness, attention to details, and modifications (done properly and part of an integrated theme).
