The dB Drag Racing Association (dBDRA) will be offering 3 formats of car stereo competition at Slamology. dB Drag Racing, Bass Race and Freestyle. dB Drag Racing is a bracket style elimination format of competition where competitors will qualify on Saturday in 1 of 14 classes and then the top 8 in each class will compete head-to-head on Sunday in the elimination rounds.  Bass Race is a format based on contestant skill and SPL. Contestants qualify in 1 of 4 SPL classes and then the top 8 in each class will compete head-to-head. Freestyle is the newest dB Drag competition format intended to provide auto sound enthusiasts with a streamlined competition experience. Unlike the traditional dB Drag Racing “Head-Head” style competition, the Freestyle class allows the competitor to compete solo in the lanes. This format is geared towards daily driver style competitors and car show enthusiasts that would like to see how loud their system is without competing against another competitor in the lanes. Competitors at Slamology will accrue 3X points, obtain certified scores, and have the ability to set World Records.
