Diamond Audio 98 - 13 Harley Davidson® Road Glide 4-Speaker System - DA9813RGSP4

Revitalize Your Legend: 1998-2013 Road Glide 4-Speaker High-Output Pro Audio

Introducing the Diamond Audio DA9813RGSP4, a pro-audio caliber 4-speaker sound pack purpose-built for the 1998–2013 Harley-Davidson Road Glide. This system is the definitive solution for hardcore riders who refuse to compromise on volume or clarity. 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 heart of this system is the MP Series high-output speakers. Both the 6.5” fairing coaxials and the 6x9” saddlebag drivers are equipped with powerful integrated compression tweeters engineered for extreme projection and surgical detail. To ensure a seamless upgrade, the kit includes DHDMCA adapter rings for the fairing and the MSMP692LK13 Lid Kit for a precision saddlebag fit. Driving this massive array is the MICRO4V2 Amplifier, a high-efficiency 4-channel Class D powerhouse that provides unmatched clarity and the massive dynamic headroom needed for crystal-clean, high-decibel loudness across the entire bike.

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.
