Car-audio bass strips Miami bass to bare sub-frequencies: hard 909/808 kicks plus sine waves

Car-audio bass is a subgenre of Miami bass built around physical low-frequency pressure for large car and club subwoofer systems. It strips the music down to its most bass-heavy elements: extremely hard TR-909 kicks combined with sine waves, or the classic TR-808 kick, or sometimes just a sine wave on its own. The teachable idea is that the sub-bass itself becomes the content, not an accompaniment: when the goal is felt bass on a big system, percussion and melody can be pared away until little remains but tuned low-frequency energy. Artists cited include DJ Laz, DJ Magic Mike, and Techmaster P.E.B.
