Description


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

Introducing the Diamond Audio DA1423SGSP4, a precision-engineered, four-speaker 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. Providing the muscle for this front-and-rear stage setup is the Micro V2 Series 4-Channel Class D amplifier, a masterpiece of efficiency providing massive dynamic headroom and crystal-clean loudness while maintaining a compact, heat-dissipating footprint perfect for fairing integration.

The DA1423SGSP4 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 high-performance MSMP692LK cut-in lid kit, this system offers a seamless factory look with the ultimate high-performance audio experience.
