Diamond Audio 14 - 23 Harley Davidson® Street Glide 2-Speaker System - DA1423SGSP1

Diamond Audio DA1423SGSP1 — 2014–2023 Harley-Davidson Street Glide 2-Speaker Audio System

The Diamond Audio DA1423SGSP1 is a complete, plug-and-play audio upgrade engineered specifically for 2014–2023 Harley-Davidson Street Glide (FLHX) models. Purpose-built for the "Rushmore" fairing geometry and factory head-unit output curves, this system delivers studio-quality clarity and road-dominating volume — even at 80+ MPH.

The acoustic core features the Motorsports HXM Black Series 6.5" coaxial speakers, built with high-modulus carbon fiber cones and bridge-mounted high-output PEI dome tweeters for surgical detail that cuts through wind and engine noise. IP65-rated for waterproof and UV resistance, these drivers are built for every condition on the road. Power is delivered by the MICRO V2 Series 2-Channel Class D amplifier — 125W RMS per channel (250W total) — offering massive headroom and unmatched thermal stability in a compact fairing-mount footprint.

Signal integrity is maintained by the MSRCA2 2-Channel Direct RCA Harness and MSPWHR 100% OFC Power Harness, bypassing factory bottlenecks for a noise-free, high-current connection. Model-specific '14–'23 Street Glide integration software delivers an optimized EQ flash for perfect factory radio synchronization, while OEM-fit DHDSG fairing grilles complete the seamless factory-look install.
