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 (tool included) in order to get the full potential and capacity out of your amplifier and speakers so your music will be loud and clear up to 100 mph!

The Volunteer Audio Stage 4 Hertz amplifier and speaker system includes the amplifier and 1 set of Hertz 6.5” SX165NEO and 1 set of SV165NEO speakers to drop in your front fairing and rear saddlebag speaker locations. Roadglide or Shark nose fairing bikes require an amp mounting plate that is included in this package. The amp comes mounted to the amp plate and is wired and ready for the addition of the new speakers. This combination is a perfect match for the environment of your Harley Davidson. The amplifier is a compact amplifier that is IP64 rated so you do not have to worry about moisture, these Hertz speakers also have weather- resistant cones that will stand up to any moisture that comes their way.

When we send out this Stage 4 package, the amplifier is pre-wired to plug into your factory radio and keep your factory speaker wiring intact so it can be used with the Hertz speakers we send. We have the amp gains already set to the maximum setting for loudness WITHOUT distortion of the speakers. We do not want any trouble with blown speakers you’ve had enough of that already, so our goal is to get the most sound out of the speakers clearly. Once you plug into the factory radio the power and ground wires that are attached to the amp will have to be ran to the battery and connected, you will also install the fuse in the fuse block that is included in the wiring.

The factory radio flash tool is included in this package. This tool is yours to keep, if you do not feel the tool is a necessary addition to your garage, we also offer a loaner tool program you can utilize.

This Stage 4 kit is next step to your dream audio system for your Harley. We also have Stage 2, Stage 6, Stage 8 and even Stage 10 speaker packages! 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.
