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

Introducing the Diamond Audio DA1423SGSP3R , a precision-engineered, four-speaker flagship sound pack purpose-built for 2014–2023 Harley-Davidson Street Glide models. This comprehensive system is the ultimate cockpit and rear-stage transformation, designed for the modern rider who demands high-definition source control, immersive surround sound, and surgical clarity at 80+ MPH.

The command center of this system is the MSHD14 Plug-N-Play Digital Media Receiver , which replaces the restrictive factory head unit with a high-voltage pre-amp signal path and modern smartphone connectivity. Providing the muscle is the Micro V2 Series 4-Channel Class D amplifier , a masterpiece of efficiency providing massive headroom for both the fairing and saddlebag lids while maintaining a compact, heat-dissipating footprint optimized for fairing integration.

Acoustic excellence is delivered through the all-new Motorsports HXM Black Series  speakers, featuring a 6.5" front stage and a matching 6x9" rear lid conversion. Re-engineered with cutting-edge carbon fiber cones  and oversized high-output tweeters, these speakers provide louder, cleaner, and more detailed sound—specifically tuned to cut through intense wind and road noise. With the included MSPWHR OFC Power Harness , MSRCA2 signal kit , and specialized integration software, the DA1423SGSP3R  ensures the cleanest signal path and the ultimate high-performance audio experience.
