The front stage is anchored by our pro-audio MP Series speakers , featuring integrated compression tweeters engineered for extreme projection and surgical detail—essential for cutting through wind and pipe noise at 80+ MPH. The rear stage is powered by HXM Black Series speakers , utilizing carbon fiber cones to provide a clean, powerful fill for the passenger. Driving this massive configuration is the Micro V2 Series 4-Channel Class D amplifier , delivering the massive dynamic headroom required for crystal-clean loudness across all four channels.
The DA1423SGTP2R ensures total system integrity through the MSTLINK T-Harness and MSPWHR OFC Power Harness , utilizing 100% Oxygen-Free Copper to eliminate signal resistance. Finished with OEM-fit DHDSG fairing grilles and DHDRGU rear universal grilles , this system delivers the cleanest signal path, flawless factory integration, and the ultimate high-performance audio experience for the modern Harley rider.
