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 and Infinity 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 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 Hertz HMP4D amplifier and 2 sets of Infinity 6.5” KAPPAPERFECT600X to replace your factory front fairing and in either your factory lower fairings or your factory tour-pack speaker locations, and the speaker grills needed for the speakers in the lower fairing or tour pack. This combination 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, and the Hertz speakers 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 Infinity 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.
This Stage 4 kit is next step to your dream audio system for your Harley. We also have 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!
