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

Introducing the Diamond Audio DA1423SGSP3 , a precision-engineered, four-speaker flagship sound pack purpose-built for the 2014–2023 Harley-Davidson Street Glide. This is not just an upgrade; it is a complete acoustic overhaul designed for the modern rider who demands immersive, studio-quality audio and relentless clarity at 80+ MPH.

At the heart of this system are the all-new Motorsports HXM Black Series  speakers, featuring a 6.5" front stage and a high-performance 6x9" rear lid conversion. Re-engineered with a cutting-edge carbon fiber cone  and an oversized, high-output tweeter, these speakers deliver unparalleled transient response and surgical detail across the entire motorcycle. Driving this massive four-speaker configuration is the Micro V2 Series 4-Channel Class D amplifier , a masterpiece of efficiency providing massive headroom for both the fairing and bag lids while maintaining a compact, heat-dissipating footprint perfect for fairing integration.

The DA1423SGSP3  ensures total system integrity through our dedicated RCA Harness Kit  and specialized integration software , bypassing factory bottlenecks to provide the cleanest signal path possible. Combined with the MSPWHR OFC Power Harness , this kit utilizes 100% Oxygen-Free Copper to eliminate resistance and signal noise. Finished with the OEM-fit DHDSG grilles  and the premium MSHXM69F2BKLK lid kit , this system offers a seamless factory look with world-class Diamond Audio performance.
