Revitalize Your Legend: 1998-2013 Street Glide High-Output Audio Evolution

Introducing the Diamond Audio DA9813SGSP2R , the ultimate flagship high-output sound pack purpose-built for 1998–2013 Harley-Davidson Street Glide models. This comprehensive "R-Series" system is the definitive choice for riders seeking a total source-to-speaker revolution—merging high-definition digital media control with pro-audio compression technology to deliver extreme volume and surgical clarity that dominates the open road.

The command center is the MSHD9813SG Plug-N-Play Digital Media Receiver , replacing the aging factory head unit with a high-voltage digital signal path and modern smartphone connectivity. The acoustic powerhouse features our MP Series speakers , equipped with integrated compression tweeters  engineered for extreme projection and crisp detail—specifically designed to cut through intense wind, exhaust, and road noise at high-speed riding.

To ensure a flawless fit, the kit includes DHDMCA adapter rings , allowing the massive 6.5" MP Series drivers to integrate perfectly into the factory 5.25" locations. Power is supplied by the MICRO2V2 Series 2-Channel Class D amplifier , providing unmatched efficiency and the dynamic headroom required for crystal-clean loudness without distortion. With the MSPWHR OFC Power Harness  and specialized '98-'13 Street Glide software , the DA9813SGSP2R  ensures the cleanest signal path and the ultimate high-performance audio experience for the modern rider on a classic machine.
