Bigger, better sound for your Harley

This speaker and amp kit is designed to bring powerful Infinity sound to 2014-22 Harley-Davidson Street Glide and 2015-22 Road Glide motorcycles equipped with factory fairings and saddlebags. The kit includes two pairs of Infinity Kappa Perfect speakers, plus a 4-channel amplifier and all the gear you'll need to install them. Everything goes in without cutting or splicing, and you won't need to have your dealer re-flash the factory receiver.

Speakers front and rear

Infinity Kappa Perfect speakers are built to perform in motorcycle applications, with an IPX5 waterproof rating that ensures they'll stand up to the elements. Infinity uses a basalt fiber Plus One™ woofer for durability and responsiveness, while the 1" edge-driven dome tweeters deliver smooth highs that cut through wind and road noise.

This kit includes a pair of 6-1/2” Infinity Kappa Perfect speakers for the fairing, plus another pair of 6”x9” models for the saddlebags. Thanks to their removable tweeter design, you can install these speakers as components or coaxials.

A small amp with big power

Infinity's Kappa Perfect 5004A amplifier puts out four channels of 75 watts RMS from a chassis about the size and shape of a standard building brick. This compact, rugged amp is made for powersports use, so your speakers will get all the power they need to rock while you roll.

A removable weather-proof panel protects the controls, while the tough aluminum chassis and conformal-coated circuit boards will help keep the music playing even when the going gets dirty or wet.

Installation made easier

This kit comes with all the brackets and harnesses you'll need to install everything in your Harley-Davidson. As we mentioned earlier, this is about as close to “plug and play” as an installation gets, plus you won't need to re-flash the factory receiver.
