The Rockford Fosgate HD9813RG-STG2 4-channel amp Motorcycle Amplifiers is a serious upgrade for 1998–2013 Harley-Davidson Road Glide riders who want clean, loud, and reliable sound on every ride. The high-output M5-800X4 amplifier delivers up to 100 watts RMS per channel with flexible 2Ω and 4Ω operation, plus up to 200 watts bridged when you want to push your system further. It is built for riders who want strong front-stage clarity and the option to expand their audio setup without sacrificing control or sound quality.
This system is built to handle real riding conditions without breaking down or sounding harsh. Element Ready engineering protects against water spray, UV exposure, dust, vibration, and corrosion with marine-grade sealing and epoxy-coated circuitry. Class-AD high-efficiency design keeps power strong while reducing strain on your charging system, so you can ride longer with high-volume audio. CLEAN gain calibration with clip indicators makes tuning simple and distortion-free, while PRESET optimization helps quickly align EQ, crossover, and gain settings for Rockford systems. Add in a fully adjustable crossover network, Punch EQ bass and treble control, and included TMS6RG 6.5 inch fairing speakers, and you get a complete plug-and-play upgrade with CEA-2006 certified power you can trust.
