Elevate Your Ride with the Ultimate 2014-2023 Street Glide Audio Evolution

Introducing the Diamond Audio DA1423SGSP5R, a precision-engineered, four-speaker flagship sound pack purpose-built for 2014–2023 Harley-Davidson Street Glide models. This is the definitive high-performance audio overhaul, designed for the modern rider who refuses to compromise on source quality, surgical precision, or crystal-clear clarity—even at 80+ MPH.

The foundation of this flagship system is the MSHD14 Plug-N-Play Digital Media Receiver, replacing the factory head unit with a high-voltage digital signal path and modern smartphone integration. The acoustic stage features our brand-new Motorsports Neo Coaxial Series speakers. Equipped with high-performance compression tweeters and advanced neodymium motor structures, these speakers are engineered for extreme projection and crisp detail—perfect for cutting through intense wind and road noise.

Driving this massive audio stage is the MICRO84U Amplifier, a masterpiece of Class D efficiency that delivers unmatched dynamic headroom and clean, powerful loudness. With a heat-dissipating footprint optimized for fairing integration and a pure signal path maintained by the MSPWHR OFC Harness and MSRCA2 signal kit, the DA1423SGSP5R delivers a flawless, high-definition audio experience that defines the industry standard for the 2014-2023 platform.
