Revitalize Your Legend: 1998-2013 Road Glide 4-Speaker Neodymium Elite Digital Audio Evolution

Introducing the Diamond Audio DA9813RGSP5R , the definitive flagship 4-speaker sound pack purpose-built for 1998–2013 Harley-Davidson Road Glide models. This comprehensive "R-Series" system is the ultimate solution for riders seeking a total source-to-speaker revolution—merging high-definition digital media control with our most advanced Neodymium acoustic stage to dominate the highway.

The command center is the MSHD9813RG 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 foundation features our flagship Neo Coaxial Series speakers  (6.5" for the fairing and 6x9" for the saddlebag lids). These premium drivers utilize high-flux Neodymium magnets and high-performance compression tweeters  designed for extreme projection and crisp detail—perfect for cutting through wind and engine noise. Providing the relentless muscle is the MICRO84U Amplifier , a high-current Class D powerhouse that delivers unmatched efficiency and the massive dynamic headroom needed for clean, powerful loudness across the entire bike.

The DA9813RGSP5R  ensures total system integrity through the MSPWHR OFC Power Harness , specialized '98-'13 Road Glide software , and the MS692NEO2LK13 Lid Kit  for seamless saddlebag integration. Finished with custom DHDRG13 fairing grilles  featuring the Diamond Logo, this system ensures the cleanest signal path, flawless factory integration, and the ultimate high-performance audio experience for the modern rider on a classic machine.
