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

Introducing the Diamond Audio DA9813RGSP3R , the ultimate flagship 4-speaker sound pack purpose-built for 1998–2013 Harley-Davidson Road Glide models. This comprehensive "R-Series" system is the definitive solution for elite riders seeking a total source-to-speaker revolution—merging high-definition digital media control with a 360-degree high-fidelity acoustic stage that dominates 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 brand-new Motorsports HXM Black Series  speakers (6.5" for the fairing and 6x9" for the lids). Re-engineered with cutting-edge carbon fiber cones  and oversized high-output tweeters, these drivers deliver louder, cleaner, and more detailed sound—essential for cutting through wind and engine noise. Providing the relentless power is the MICRO4V2 Amplifier , a high-efficiency 4-channel Class D powerhouse that delivers unmatched clarity and the dynamic headroom needed for crystal-clean loudness across the entire bike.

The DA9813RGSP3R  ensures total system integrity through the MSPWHR OFC Power Harness , specialized '98-'13 Road Glide software , and the MSHXM69F2BKLK13 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.

• Complete Source Overhaul:  Includes the MSHD9813RG head unit for full digital media control and superior signal processing over the obsolete OEM radio.
• Full-Stage 4-Speaker Integration:  Complete upgrade for both the Sharknose fairing and saddlebags for a total immersive surround experience.
• Modern Carbon Fiber Definition:  Advanced cone technology ensures musical integrity and surgical detail even against aggressive environmental noise.
• Pure Signal Path:  100% Oxygen-Free Copper (OFC) wiring and direct digital integration eliminate signal degradation and maximize amplifier efficiency.
