Diamond Audio 14 - 23 Harley Davidson® Road Glide 4-Speaker System - DA1423RGSP4R

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.
