Let’s talk CVO Boom Stage 2 systems

We know…you upgraded to the Boom Stage 2 system and are still disappointed. You spent a lot of money and didn’t get nearly the sound you though you would have. We hear this 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 Boom Stage 2 sound system, but it will require a flash in order to get the full sound potential out of your amplifier and speakers so your music will be loud and clear up to 100 mph!

The Volunteer Audio CVO Stage 4 Hertz amplifier and speaker package includes the Hertz HMP4D, 1 set of Hertz 6.5” SX165NEO, and 1 set of Precision Power 5×7” speakers to replace your factory front fairing. 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. All necessary wiring is included in the package, you will not need any other wiring or hardware to complete this installation. The lower fairing speakers will require new speaker grills which are also included.

This combination of Hertz products is a perfect match for the environment of your Harley Davidson. The HMP4D amplifier is a compact amplifier that is IP64 rated so you do not have to worry about moisture, these Hertz and Audison speakers also have weather-resistant cones that will stand up to any moisture that comes their way.

We do not want any trouble with blown speakers, you’ve had enough of that already. Our goal is to get the most sound out of the speakers clearly with no distortion. 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.

This Stage 4 kit is next step to your dream audio system for your Harley. We also have Stage 8 or even Stage 10 speaker packages, just ask us about what adding a subwoofer does for your sound! 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!
