Diamond Audio 14 - 23 Harley Davidson® Street Glide 4-Speaker System - DA1423SGSP3

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.
