Introducing the Diamond Audio DA1423SGSP2 , a precision-engineered, high-output 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 hardcore rider who demands maximum sound pressure levels (SPL) and surgical projection at 80+ MPH.
At the heart of this system are the pro-audio grade MP Series speakers . Equipped with a powerful integrated compression tweeter engineered for extreme projection and crisp detail, these speakers are specifically designed to cut through the most aggressive wind and road noise. Driving this front stage is the Micro V2 Series 2-Channel Class D amplifier , a masterpiece of efficiency providing unmatched dynamic headroom and crystal-clean loudness while maintaining a compact, heat-dissipating footprint perfect for fairing integration.
The DA1423SGSP2 ensures total system integrity through our dedicated 2-Channel 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 , this system offers a seamless factory look with the ultimate high-performance audio experience.
