Diamond Audio 14 - 23 Harley Davidson Street Glide 4-Speaker System - DA1423SGSP4

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.

Maintenance Tips

• Moisture protection: Ensure fairing, lid, and amp areas stay sealed; avoid direct pressure washing into speaker grills.
• Electrical health: Check battery voltage regularly—low voltage causes distortion or amp protection mode.
• Gain settings: Set amp gain correctly (avoid maxing volume); clipping is the #1 cause of speaker damage.
• Wiring check: Periodically inspect OFC power/ground/RCA connections for corrosion, looseness, or heat wear.
• Speaker care: Clean grills gently; avoid solvents that can damage cone surrounds or coatings.
• Heat management: Keep amplifier vents clear—overheating reduces output and lifespan.
• Firmware/system tuning (if applicable): Recheck DSP/head unit settings after updates or battery disconnects.
