Competition Formats
IASCA’s competition formats cater to all types of car audio enthusiasts. Each has its own specific focus, and one that fits your style.
Sound Pressure Level / SPL
IASCA’S SPL Divisions focus on both interior and exterior sound performance. Both use SPL and dB or decibel measurement from inside and outside the car. Bass Boxing focuses on exterior performance and IdBL focuses on the interior performance.
Both are demanding formats and both are definitely crowd pleasers!
BASS BOXING
SPL Challenge
This format is a Sound Pressure Level or SPL competition using full range music as the main judging criteria. Bass Boxing pits several competitors against each other until one competitor prevails as “Champion”.
In competition, the full range of music, not just bass, must be heard cleanly and clearly by everyone, including judges and spectators.
IdBL
SPL Challenge
IdBL Divisions are based on experience, industry position of the competitor and level of modification to the vehicle. IdBL Classes are based on the cumulative total of all subwoofer cone surfaces in square inches.
Determining the winner is simple; the highest score in each class wins!

NiteGlow evaluates the competitor’s vehicle accent lighting in both interior & exterior applications. Innovation and quality of design and implementation wins here.
