The Rockford Fosgate HD9813SG-STG3 is a Stage-3 motorcycle audio kit designed to deliver unparalleled performance and clarity on the road. This comprehensive system includes two 6.5" Element Ready fairing speakers, two 6x9" Element Ready retrofit saddlebag speakers, an 800W 4-channel IPX6 Element Ready amplifier, and a dedicated amplifier installation kit (RFK-HD9813M5). The speakers are custom-tuned to overcome wind, road, and exhaust noise at highway speeds, providing a superior audio experience. The kit features a Plug-and-Play design with direct-connect wiring harnesses for Harley-Davidson models, and components bolt to factory attachment points, requiring no drilling or cutting for installation. This kit is designed for specific 1998-2013 Harley-Davidson Street Glide (FLHX) and Electra Glide Standard (FLHTI) models. However, several compatibility notes apply: - If used with the PMX-HD9813, the radio is not compatible with factory amplified systems, CB, intercom, rear volume controls, rear speakers on 1998-2005 Ultra models, and factory satellite radio systems. - The saddlebag kit is compatible only with ABS plastic lids, not fiberglass lids. - The saddlebag kit is not compatible with the H-D® Power Lock Kit. - Installation on CVO™ and Screaming Eagle™ models is not plug-and-play and will require modification. - Tour-Pak® speakers are not 100% plug-and-play compatible and may require work-arounds.
