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

Introducing the Diamond Audio DA9813SGSP4 , a precision-engineered, four-speaker high-output sound pack purpose-built for 1998–2013 Harley-Davidson Street Glide models. This system is the definitive choice for hardcore riders and audio purists who demand maximum output and surgical clarity from a classic platform. Engineered to transform the acoustic signature of the legacy Batwing fairing and saddlebags, the SP4 delivers a massive soundstage that commands attention.

The acoustic foundation features our pro-audio MP Series speakers  in a complete 4-speaker array. These drivers are equipped with powerful integrated compression tweeters  engineered for extreme projection and crisp detail—essential for maintaining musicality at 80+ MPH. To bridge the gap between classic design and modern power, the kit includes DHDMCA adapter rings  to fit 6.5" drivers into the fairing, and the MSMP692LK13 Cut-In Lid Kit  to house 6x9" compression drivers in your bags. Driving this powerhouse is the MICRO4V2 Series 4-Channel Class D amplifier , providing unmatched efficiency and the massive dynamic headroom required for crystal-clean loudness.

The DA9813SGSP4  ensures total system integrity through the MSPWHR OFC Power Harness  and specialized '98-'13 Street Glide software  for optimized digital integration. Finished with custom DHDSG13 fairing grilles , this system ensures the cleanest signal path, flawless factory integration, and the ultimate high-performance audio experience.
