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

Introducing the Diamond Audio DA1423RGSP3R , a precision-engineered, 4-speaker flagship sound pack purpose-built for 2014–2023 Harley-Davidson Road Glide models. This comprehensive "R-Series" system is the definitive solution for elite riders who demand a total source-to-speaker transformation—combining high-definition digital media control with a 360-degree high-output acoustic stage that dominates at highway speeds.

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 brand-new Motorsports HXM Black Series  speakers in both the fairing and the saddlebags. Re-engineered with cutting-edge carbon fiber cones  and oversized high-output tweeters, these drivers deliver louder, cleaner, and more detailed sound—specifically tuned to cut through intense wind and road noise. Providing the muscle is the MICRO4V2 Series 4-Channel Class D amplifier , delivering massive dynamic headroom and crystal-clean loudness across the entire bike.

The DA1423RGSP3R  includes the MSHXM69F2BKLK Cut-In Lid Kit , integrating 6x9” HXM Black Series 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.
