2-Speaker Audio System - Select 2014-2022 Harley-Davidson®


Saddle Tramp has partnered with HARMAN to create this all-in-one 2-speaker audio system to fit 2014-2022 Harley-Davidson® Street Glide and 2015-2022 Road Glide motorcycles equipped with factory fairings. Everything needed to install an impressive aftermarket audio system is conveniently included in one package: two of HARMAN’s Kappa Perfect 6.5” speakers and a 4-channel amplifier, paired with an assortment of Saddle Tramp products that make installation easy. This assortment of Saddle Tramp products includes a DSP interface to reflash the OE radio, pre-tuned by HARMAN Acoustic Sound Engineers to provide best-in-class audio performance. This system is truly plug-n-play and does not require the installer to cut any wires. It also comes with step-by-step instructions to ensure results that installers can be proud of.

HARMAN’s Infinity Kappa Perfect Speakers deliver the ultimate listening experience on two wheels. They feature a lightweight, premium design and factory look, and are durably constructed to last for miles and miles. They combine water-resistant construction, patented Plus One™ basalt fiber woofer cones, and edge-driven polyphenylene sulfide dome tweeters, providing an amazing soundstage with great bass and silky-smooth highs. The brand’s high-performance amplifiers are engineered to meet the demands of compact installation locations and withstand extreme environments. They feature Molex connectors to attach the Saddle Tramp DSP and a small footprint to easily fit into tight fairings.
