For Competitors Who Don’t Settle for Average

To beat the competition and be the loudest on the streets, you have to think smarter, buy smarter, and build smarter. Helping you become that guy, Soundstream is proud to present the Tarantula XTREME POWER Series — the ultimate SPL-class amplifier built for those who demand unrelenting output from their audio setup.
