The Trunk Division, with 2 “Pressure Classes”, is intended for vehicles with systems installed in the Trunk.

The Street Division, with 5 “Pressure Classes”, is intended for competitors with some vehicle and system modifications allowed. Vehicles are still intended to be daily drivers, must have a functional OEM backseat, and not SPL specific.

Modified Street has 4 “Pressure Classes” and is intended for vehicles which do not have back seats, have no-wall builds, or other

installations which are done to the B-pillars.

The Modified Division, with 5 “Pressure Classes”, is intended for vehicles and systems that are designed to maximize sound pressure level, including woofer walls and pickup truck cut-throughs, but are still capable of being daily drivers.

The “Radical X” Division, has 2 classes (one clamped class with maximum of 4000 pressure rating and one unlimited) for extremely modified exhibition systems/vehicles, is intended for hard-core SPL Competitors with unusual or concept vehicles.


The “Park & Pound” Format, with 5 “Pressure Classes”, is intended to measure sound pressure levels outside the vehicle, while playing full-range music. In addition to the General Rules, sensor will be placed 72” (6’) from the outside edge of a marker on the ground (usually a cone), on passenger side of the vehicle; 54” (4.5’) off the ground on MECA approved stand.  Final score is “Average” for 30 seconds.
