J & M 400W 2-Channel Amp Kit - 15-20 Roadglide Fairing JAMP-400HR15

Factory audio systems in touring bikes weren't designed for highway noise—they fade into the roar at cruising speeds. The J & M 400W 2-Channel Amp Kit delivers 200 watts RMS per channel into your Roadglide's fairing speakers, restoring clarity and presence without the distortion that comes from maxing out stock head units. Dialed in specifically for this platform, you get the volume and fidelity that transforms long-distance rides from frustrating to genuinely enjoyable.

Installation is straightforward—the amplifier mounts to a custom stainless steel bracket system that secures it inside the batwing fairing, and plug-and-play wiring harnesses eliminate guesswork. Heavy-gauge power and ground wires connect directly to the battery with factory fusing, and all hardware and instructions ship with the kit.
