About Creative Audio Creative Audio opened in 1991 and has grown into a multi-location specialty retailer with seven stores across Missouri and Arkansas. We support enthusiasts, installers, and everyday customers with product knowledge, practical guidance, and a service-first approach that extends beyond the checkout. We are deeply invested in performance-focused audio across categories: car audio, marine, powersports, and home audio. That means more than selling gear — it means understanding system matching, power requirements, signal integration, real-world installation considerations, and the small details that determine whether a system performs the way it should. Our teams work daily with source units and processors, amplifiers, speakers, subwoofers, wiring and installation accessories, sound treatment, and integration solutions. We also support remote start and vehicle security categories for customers who want added convenience and protection. Creative Audio employs Mobile Electronics Certified Professionals, and we support customers before and after the sale. If you are unsure about compatibility, installation requirements, or what is included, message us through with your application details and we will help you make an informed decision.
