Revitalize Your Legend: 1998-2013 Street Glide High-Output Audio Evolution

Introducing the Diamond Audio DA9813SGSP4R , the definitive flagship 4-speaker sound pack purpose-built for 1998–2013 Harley-Davidson Street Glide models. This comprehensive system is the ultimate solution for elite riders seeking a total source-to-speaker revolution—merging high-definition digital media control with an extreme-output acoustic stage that dominates the open road.

The command center is the MSHD9813SG Plug-N-Play Digital Media Receiver , replacing the aging factory head unit to provide a high-voltage digital signal path, modern smartphone connectivity, and a full-color interface. The acoustic powerhouse features our pro-audio MP Series speakers  in a complete 4-speaker configuration. Equipped with powerful integrated compression tweeters , these drivers are engineered for extreme projection and surgical detail—specifically designed to cut through intense wind and exhaust noise at high speeds. To bridge the gap between classic design and modern power, the kit includes DHDMCA adapter rings  for the fairing and the MSMP692LK13 Cut-In Lid Kit  for the saddlebags. Providing the muscle is the MICRO4V2 Series 4-Channel Class D amplifier , delivering the efficiency and dynamic headroom needed for crystal-clean loudness across the entire bike.

The DA9813SGSP4R  ensures total system integrity through the MSPWHR OFC Power Harness  and specialized '98-'13 Street Glide software . Finished with custom DHDSG13 fairing grilles , this system ensures the cleanest signal path, flawless factory integration, and the ultimate high-performance audio experience for the legendary Street Glide.
