IASCA Competitors are a Unique Breed. Sure, they like the car show thing and hangin' out in great settings like the Spring Break Nationals' TUNER JAM in Daytona Beach, But it's a way bit different than just that.

These dedicated people constantly strive to build and tune the best sounding and LOUDEST systems on the planet. They read and know the IASCA rules and enter into contests of Sound Quality and Installation. Some build systems with volume levels that absoulutely SLAY!

For over 20 years, IASCA’s Rules for Car Audio Competition are considered the Industry Benchmark in system evaluation recognized Worldwide.
