The Whelen SA315U Series speaker delivers powerful, attention-grabbing sound in a compact, rugged design—ideal for patrol cars, undercover units, and volunteer emergency vehicles. Built with a durable all-weather nylon composite housing and a front-loaded, powder-coated driver, the SA315 is made to perform reliably in the harshest environments.

Offering superior tone clarity and a broader frequency range than many comparable models, this speaker ensures your signals are unmistakably heard. Its low-profile form fits neatly behind the grille or on the radiator cross member, with quick and easy installation using either a universal bracket or vehicle-specific mounts for a seamless fit.

Whether you're outfitting a fully marked cruiser or a covert response vehicle, the SA315 Series delivers trusted performance and crystal-clear sound when every second counts.
