By integrating high-performance compression technology into both the Sharknose fairing and the saddlebag lids, the SP4 delivers an aggressive, immersive soundstage designed to cut through extreme wind, exhaust, and road noise during high-velocity touring.

The DA9813RGSP4 ensures total system integrity through the MSPWHR OFC Power Harness and specialized '98-'13 Road Glide software for optimized signal 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.
