2025 H-D® Stage III

Harley-Davidson Audio Powered by Rockford Fosgate

The Harley-Davidson® Audio powered by Rockford Fosgate® Stage III redefines motorcycle audio with aggressive performance and styling, setting a new standard and transforming the riding experience.

New this year are the 6.5-inch fairing speakers and 6x9 saddlebag speakers, both designed with a 3-way bridge-mounted system to deliver next level performance. The 6.5-inch fairing and 6x9 saddlebag speakers boast 250-watts per driver power handling. Additionally, we've introduced some design updates, including Hot Rod Red trim rings and matching red badging on the grilles.

Designed exclusively for:
• 2023.5+ CVO
• 2024+ Road Glide
• 2024+ Street Glide

Product Overview

Introducing the 2025 lineup of Harley-Davidson powered by Rockford Fosgate Stage III speakers. Purpose-built for the 2025 Street and Road Glide models, these speakers were designed by riders, for riders.

Supercharged Amplification

This supercharged integrated digital DSP amplifier provides all the audio amplification you are looking for. It delivers better sound quality, no interference or noise, all in a smaller footprint than ever before. With 500 total watts of power, your audio system will deliver that on-road audio experience that is second to none. And superior thermal management its designed to run all day and never run out of power.

Factory Equipped

True factory audio. Harley-Davidson and Rockford Fosgate worked directly together to integrate the audio system into the design of the bike. This means no complicated installation, no un-need wiring, and all direct from the factory connections for flawless audio integration.

Rider Centric Speakers

More powerful speakers that are engineered for the ride and how you ride. We measured rider positioning and designed them specifically so that they are always directly pointed at you. Making sure the music is heard over the wind, road, and exhaust noise.

Element Ready™

Purpose built for the harsh motorcycle environment. The speakers and amplifier are designed to stand up to water, dirt, UV, and motorcycle vibration, ensuring that your audio system will stand the test of time.

Primary Amplifier

Power and Performance

The supercharged 500-watt amplifier produces 125-watts of continuous power into each of the 4-channels utilizing Rockford Fosgate’s design philosophy of producing higher dynamic power under real-world conditions for accurate musical transients and deep bass. The integrated DSP features a dynamic EQ that can be adjusted without distorting the outputs for optimum sound quality and speaker longevity.

Fairing Speakers

Long Throw, High Output

The 6.5” 3-way speakers feature a long throw, high output design for the high quality sound and performance.  The speaker features a curvilinear poly cone with 20% carbon fill for a lightweight and stiff assembly. The neodymium magnet has 10x the energy density over traditional ceramic ferrite, resulting in a motor that’s 35% lighter and 65% smaller, and is matched with an oversized 2” four-layer voice coil for 250-watts of power handling.

Saddlebag Speakers

Low-End Extension

The 6x9” 3-way speakers feature injection molded Santoprene surrounds for low distortion and internal damping for outstanding mid-bass. This surround combined with a curvilinear poly cone extends the frequency range for enhanced low-end response. The motor structure utilizes a large 2-inch voice coil and is combined with an ultra-efficient dual neodymium magnet for increased output and performance for an impressive 250-watts of power handling.

R-TUNE

We packed a of ton technology into these audio systems, so first let’s talk about R-Tune. When we created R-Tune, it was all about putting the rider first and creating a specific tune for the on-bike audio experience. To do that, we first measured rider positioning on the bike, and then engineered specific left and right speakers so they were always pointed directly at the rider, which makes sure the audio is hitting right where it needs to. The system was then tuned for real world riding, specifically to battle noise - Road noise, exhaust noise, wind noise. At the end of the day, all this technology delivers the audio experience that you’ve always wanted on a bike.

M-DEQ

M-DEQ is Motorcycle Dynamic EQ. The real hero of M-DEQ technology is the amplifier’s DSP. The DSP or Digital Signal Processor, basically controls the sound of the music. Ours is incredibly intelligent and changes EQ points in real time. This means that it understands how you ride and changes the audio experience accordingly. So, if you are on the freeway this DSP is smart enough to know that, and changes the EQ points to make sure your audio sounds excellent… No matter what the speed.

BME

BME technology is Bass Management Enhancement. This audio system is designed to always continually adapt to speed, road, engine and exhaust noise, and as it adapts to that noise it maximizes the speaker’s bass output. So, at high and low speeds the system always creates powerful bass.

IDHS™ (Inductive Damping Heat Sink)

The speaker fins push heat away from the voice coils to reduce speaker temperature and distortion to produce the clearest-possible audio.

Bridge Mounted Design

The offset Midrange and Tweeter speaker design eliminates acoustic reflection and maximizes audio output. The specific left and right Midrange and Tweeters are also aligned for optimal riding position, making sure the audio is always directed in the proper location, giving the best on-road audio experience.

Full Range Class-D Technology

More power and less electrical fatigue. These high-efficiency amplifiers produce class leading power and don’t over-draw on the motorcycle electrical system.

ICC+

The Integrated Concealed Crossover boasts a hyper-efficient design and produces the clarity and output usually only found in traditional component speaker set-ups, plus the design allows for a quicker install.

Vibration-Tested

Tested and then re-tested to ensure supreme durability. These speakers have endured extreme conditions and then vibration validation all to make sure they stand the test of time.
