Introducing the Diamond Audio DA1423RGTP3R , the definitive flagship sound pack precision-engineered for 2014–2023 Harley-Davidson Road Glide Ultra and Limited models. This "R-Series" system is the ultimate solution for elite riders seeking a total source-to-speaker revolution—merging high-definition digital media control with a high-output acoustic stage that dominates the open road.

Driving this massive configuration is the MICRO84U Amplifier , a high-current Class D powerhouse from the Micro 8U Series that delivers unmatched efficiency and the massive dynamic headroom needed for crystal-clean loudness across all four channels.

The DA1423RGTP3R  ensures total system integrity through the MSPWHR OFC Power Harness  and the MSTLINK T-Harness , ensuring a flawless, no-cut digital integration. Finished with OEM-fit DHDRG fairing grilles  and DHDRGU Tour Pack grilles , this system provides the cleanest signal path and the ultimate high-performance audio experience for the modern Harley rider.
