Ultimate Premium Sound Package

Cut through the wind and engine noise with the Diamond Audio DA1423SGTP2, a premium, all-in-one audio powerhouse engineered specifically for your 2014-2023 Harley-Davidson Street Glide.

Built for the long haul, this kit is fully armored against the elements with UV-stable and water-resistant components. Whether you’re cruising the coast or tearing up the interstate, the DA1423SGTP2 delivers the sophisticated, high-fidelity soundtrack your Harley deserves.
