Description


Elevate Your Ride with the Ultimate 2014-2023 Road Glide Audio Evolution

Introducing the Diamond Audio DA1423RGSP4R, a precision-engineered, four-speaker flagship sound pack purpose-built for 2014–2023 Harley-Davidson Road Glide models. This comprehensive system is the definitive choice for elite riders who demand a total source-to-speaker transformation—combining high-definition digital media control with an extreme-output acoustic stage that dominates at any speed.

The command center is the MSHD14 Plug-N-Play Digital Media Receiver, replacing the factory head unit to provide a high-voltage digital signal path and modern smartphone connectivity. The acoustic foundation features our pro-audio MP Series speakers in both the fairing and the saddlebags. Equipped with powerful integrated compression tweeters , these drivers are engineered for extreme projection and surgical detail—essential for cutting through intense wind and engine noise during high-speed riding. Driving this massive configuration is the MICRO4V2 Series 4-Channel Class D amplifier, delivering the efficiency and dynamic headroom needed for crystal-clean loudness across all four channels.

The DA1423RGSP4R includes the MSMP692LK Cut-In Lid Kit, integrating 6x9” MP Series compression speakers into your factory bag lids for a seamless, aggressive look. With the MSPWHR OFC Power Harness, MSRCA2 signal kit, and specialized '14-23 Road Glide software, this system ensures the cleanest signal path and flawless factory integration for the ultimate high-performance audio experience.
