Diamond Audio 14 - 23 Harley Davidson® Street Glide 4-Speaker System - DA1423SGSP3R

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.
