Hertz Stage 4 Ultimate Plug & Play Amp And Speaker Package with Subwoofer For 2014-2025 Harley Davidson® Tri Glide Motorcycles

Can you hear your Harley speakers clearly at highway speeds?
We didn’t think so…
Tired of constantly blowing those stock speakers just to hear your music over the road noise?
We hear you loud and clear!

At Volunteer Audio, we hear this complaint all the time, and we're here to change your ride’s sound experience with a system that'll truly blow you away. Our solution allows you to keep your factory radio or Soundstream Reserve radio while upgrading your sound system to deliver crystal-clear audio at highway speeds. If you're keeping your factory radio, a quick flash is required to unlock the full potential of your new amplifier and speakers, allowing you to crank the volume and enjoy distortion-free music—even at 100 mph! This radio flash is not necessary if you're using a Soundstream Reserve radio, so you can skip that step entirely.

The Stage 4 Amplifier and Speaker System provides everything you need for a premium audio upgrade. It features a prewired amplifier, expertly matched to your system, along with a pair of high-quality speakers designed specifically for your front fairing speaker locations. This setup is built to thrive in the unique conditions of your Harley-Davidson. The compact amplifier is IP64-rated for moisture protection, while the Hertz speakers boast weather-resistant cones, ensuring they stand up to the elements with ease.

Package Includes:

• Prewired Velocity RZP2000.6 6-Channel Amplifier: A powerful, compact, all-weather amplifier that arrives prewired with its gains and filters professionally set for your factory Skyline OS infotainment system.
• 1 Pair of Hertz SX165NEO 6.5-Inch Upper-Fairing Speakers: High-output, weather-resistant speakers that replace the factory upper-fairing speakers with greater volume, clarity and detail.
• 1 Pair of Hertz SV165NEO 6.5-Inch Tour-Pak Speakers: High-performance neodymium speakers engineered to deliver powerful, clear sound from the Tour-Pak speaker locations.
• 1 Hertz HMS 12 B4-LD-C 12-Inch Subwoofer: A marine-grade, long-excursion subwoofer that adds the deep, powerful bass missing from the factory audio system.
  

Optional Add-ons:

• Techno Research Radio Flash Tool: An essential tool to flash your factory radio, unlocking the full potential of your amplifier and speakers. (Only needed if you are keeping your factory radio and do not have a SoundStream radio)
• Upper Fairing Metal Mesh Speaker Grilles: These high-quality grilles protect your speakers and keep the sleek look of your bike intact.
• Tour Pak Speaker Grilles: High-quality metal mesh speaker grilles designed to protect your Tour Pak speakers while maintaining a sleek, stylish look for your bike.
• Sound Skins Sound Deadening: Improve acoustic quality and reduce road noise, making your music clearer and richer.
• Battery Upgrade: If needed, we offer a battery upgrade to support the extra power demands of your new system.

Easy Installation and Support

At Volunteer Audio, we handle the technical details for you. Our kits are nearly “plug-and-play,” with the amplifier’s gains and filters already set. All you need to do is mount the amplifier, run the wiring to the seat and battery, and install the speakers. We provide step-by-step video tutorials and lifetime tech support to ensure you get everything just right.

We also offer Stage 6 speaker packages with Subwoofer if you’re looking for even more performance—whether it’s for scenic rides or competing in sound competitions, we’ve got you covered.

With Volunteer Audio, your bike’s sound system will sound as incredible as your ride feels. Let’s upgrade your audio and make your Harley-Davidson experience even better!

If you don’t have a Techno Research dealer nearby, we also offer a loaner tool program so you can easily flash your radio yourself.
