Metra Electronics® Teams Up with HARMAN to Create New Dealer Exclusive Motorcycle Audio Solutions

Aug 28, 2023

Holly Hill, Fla. Metra Electronics® has collaborated with HARMAN International Industries, the premier connected technologies company for automotive, consumer, and enterprise markets, to create new plug-n-play audio systems for select 2014-2022 Harley-Davidson® motorcycles that will be sold exclusively to brick-and-mortar dealers for in-store sales only. These products are in stock and shipping now and pair Harman's Infinity Kappa Perfect PowerSports Amplifiers and Speakers with DSP Processor system integration and installation equipment from Metra's Saddle Tramp® brand. Three new audio system integration kits are available for select Road Glide and Street Glide motorcycles, in addition to accessory lower fairing installation kits for twin-cooled and non-twin-cooled applications:

  • 2-Speaker Plug-N-Play Audio System (INFKP2SPKSYS)
  • 4-Speaker Plug-N-Play Audio System (INFKP4SPKSYS)
  • 6-Speaker Plug-N-Play Audio System (INFKP6SPKSYS)
  • Twin-Cooled Engine Lower Fairing Speaker Upgrade Kit (INFKPTCKIT)
  • Non-Twin-Cooled Engine Lower Fairing Speaker Upgrade Kit (INFKPNTCKIT)
  • Saddlebag Speaker Upgrade Kit (INFKP900XKIT)


Harman's Infinity Kappa Perfect PowerSports Amplifiers are high-performance multi-environment amplifiers engineered to meet the demands of small footprint-dependent installation locations and withstand extreme environments. They feature Molex connectors to mate with a Saddle Tramp DSP with a small footprint to fit into tight fairings easily. The Infinity Kappa Perfect Speakers utilize many industry-first materials, such as Basalt Fiber Woofers with Plus One™ Technology, lightweight neodymium motors, and a removable Polyphenylene Sulfide-dome tweeter, which is certified for Hi-Resolution Audio. Factory fit grills accompany the 6.5” and 6x9” speakers for a seamless look.


​​Once paired with Saddle Tramp’s DSP, Harman’s acoustic sound engineers tune the amplifiers and speakers to create a best-in-class audio performance. The DSP flattens the factory audio settings through its head unit CAN connection. Detailed work instructions and the included vehicle-specific brackets make the job simple to install and provide a factory-quality result that installers can be proud of and end consumers can do on their own.
