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 upgrade to a Soundstream Reserve radio with a thumb control module, delivering crystal-clear audio at highway speeds. With the Soundstream Reserve radio, you get superior sound and full control while you ride.

Can I Really Hear Rear Speakers When I Add Them to My Bike?

We get this question ALL the time at Volunteer Audio, so let us answer it once and for all… YES, of course, you can hear the rear speakers when they’re added to your bike!

When you purchase from Volunteer Audio, we take several steps to ensure you get the best possible sound from your rear speakers:

  • Proper Speaker Placement: When installing 6×9” speakers, we use specially designed cut-in kits that position the speaker higher in the lid. This saves space in your bag while angling the speaker toward you for better sound clarity. Most replacement lids don’t provide this benefit.
  • Ample Power for Rear Speakers: We make sure the rear speakers are powered correctly so they’re loud enough to be heard even when positioned behind you.
  • Customized Amplifier Settings: When using a factory radio, flashing it can cause the loss of fader control. We account for this by slightly adjusting the amplifier's settings to ensure the sound fades toward the rear.
  • Balanced Sound: The rear speakers won’t overpower the front ones. The front speakers point directly at you, naturally being louder, but the rear speakers surround you with fuller sound. This creates a concert-like experience and adds rich mid-bass, completing your soundscape.

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 Velocity speakers boast weather-resistant cones, ensuring they stand up to the elements with ease.

Package Includes:

  • Soundstream Reserve WHD14+ Radio with Thumb Control Module: Upgrade to the powerful Soundstream Reserve radio with an intuitive thumb control module, providing seamless audio control at your fingertips.
  • Prewired Velocity RZA1000.4 Amplifier: A prewired amplifier with gains and filters adjusted perfectly for your factory GT/GTS radio.
  • Velocity RZ65H 6.5” Upper Fairing Speakers: Premium speakers designed to fit perfectly into your bike's upper fairing, ensuring optimal sound performance for clear, rich audio.
  • American Hard Bag IP-SSK-6.5 Universal Hydrophobic Cloth 6.5" Speaker Covers: These cover your speakers to allow them to be weather-resistant.
