Can you hear your factory Harley speakers loud and clear at highway speeds?

We didn’t think so…

Are you tired of blowing those factory speakers trying to be able to hear them?

Of course you are!

These issues are something we hear ALL the time at Volunteer Audio, so we have partnered with Hertz to give you a sound experience you will be blown away with! This package will allow you to keep your factory radio when upgrading your sound system, but it will require a flash in order to get the full potential out of your amplifier and speakers so your music will be loud and clear up to 100 mph!

This Volunteer Audio Stage 4 Complete Hertz speaker system includes 1 prewired HMP4D amplifier with amp plate to mount in the Road glide, 1 set of Hertz SX165NEO 6.5” speakers, 1 set of SX690NEO 6×9” SPL Show speakers plus Kicker CVO style lids that will house the 6×9” speakers. These lids come unpainted so they can be painted to match your factory Harley color. All necessary wiring you need to connect the speakers without altering any of your factory wiring is also included. This combination is a perfect match for the environment of your Harley Davidson. The Hertz speakers have weather-resistant cones that will stand up to any moisture that comes their way.

This package will allow you to connect the Hertz HMP4D amplifier into your factory radio to power your new speakers. This package comes already wired and ready for the addition of the new speakers; for the rear speakers you will have to connect a harness to a factory 4-pin connector located inside your front fairing and run down the backbone of the bike to the back of the seat where it will tie into another set of wiring that will allow you to hook up the aftermarket speakers in your saddlebags.

We also have several different add-on packages for your Harley audio so that you can upgrade in steps. So, when you are ready for the next step in building your dream audio system for your Harley, check back with us about making your system into a Stage 6, Stage 8 or even a Stage 10 speaker system! Whether you would like to enjoy music while out riding through the country or compete in sound competitions we have the package that is just for you!

If you do not have a Technoresearch dealer near you, we do offer a loaner tool program so that you can flash the radio yourself.
