Mighty Action Sound System

Founder of Mighty Action Sound | Founder of the DMV Sound System Association |Master Builder | Cultural Steward

Waldo “Wally” Williams is a master soundman, system builder, and cultural steward with over 30 years of dedication to the global sound system movement. Born and raised in Spanish Town, Jamaica, Wally began his journey as a teenager—not just playing music, but studying the engineering, wiring, and soul of sound systems.

He started with the legendary Black Arrows (Spanish Town) and Phrequency Sound (Portmore/August Town), then built his first system, City Star, a beloved staple for community events back home.

After migrating to Washington, DC in 1994, Wally created Action International from scratch—his second full sound system. He DJed across the DMV, collaborated with Acid Sound, and played a key role in supporting Earthquake Sound during a pivotal transition.

Eventually stepping back to focus on family, Wally shipped his system back to Jamaica where Mighty Action rose to prominence in the housing schemes of Spanish Town. When distance made it hard to manage the crew, he placed the system in storage—but after rebuilding his life post-divorce, Wally returned to the scene stronger than ever.

Today, Wally runs two fully operational Mighty Action Sound Systems—one in Jamaica, one in the U.S.—both hand-built and powered by legacy. As the sole promoter of Mighty Action events, he is known for high-quality sound, cultural pride, and technical excellence.

Through the DMV Sound System Association (DSA), Wally is focused on legacy, mentorship, and community upliftment. Whether he's building systems for others, advising new soundmen, or leading events, Wally is committed to keeping sound system culture alive—with integrity, power, and pride.
