Description

 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 are here 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!

Can I really hear rear speakers when I add them to my bike? We get this question ALL the time at Volunteer Audio, so we want to answer the question once and for all…YES of course you can hear the rear speakers when they are added. When you purchase from Volunteer Audio we do several things to make sure you can hear your rear speakers:

  • When installing 6×9” we use cut in kits which position the speaker higher in the lid which takes up less room in your bag and also angles the speaker toward you so you can hear the speaker better. Most replacement lids do not do these things.
  • We properly power the rear speakers so they are loud enough to hear even when they are behind you.
  • When using a factory radio after flashing the radio you will lose fader, we take that into account and fade our amplifier settings slightly to the rear.

We know that the rear speakers won’t overpower the front speakers because the front speakers are pointing directly at you, of course they will be louder, but the rear speakers give you a more full sound that surrounds you. Which gives you a concert feeling and also gives added mid-bass.

This Volunteer Audio Stage 4 amplifier and speaker system includes your choice of a perfectly paired prewired amplifier 1 pair of upper fairing speakers and 1 pair of 6×9 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, the Hertz speakers also have weather-resistant cones that will stand up to any moisture that comes their way.

This package includes:

  • Your choice of a prewired amplifier with gains and filters adjusted perfectly for your factory GT /GTS radio
  • 1 pair of Hertz SX165NEO 6.5” upper fairing speakers
  • 1 pair of Hertz SX690NEO 6×9” saddlebag lid speakers
  • Backbone and Saddlebag quick disconnect wiring harnesses for rear speakers
  • Speaker cut in kit for lids includes template, grills and brackets to hold 6×9” speakers
  • Optional parts for this system include: upper fairing speaker grilles, Techno Research radio flash tool, Sound Skins sound deadening, and Battery 

At Volunteer Audio we work hard so you don’t have to. We make it easy for you to add an amazing sound system to your bike by completing all the prep work here. When we send this kit to you it is as close to finished as we can possibly get it so you just have to install it. We will have all the gains and filters set on the amplifier so you do not have to know how to set the adjustments. All you will have to do is mount the amplifier with provided mounting hardware, run the provided wiring to under the seat and to battery and then install the speakers. We have step by step videos showing how to complete each step of this process and also offer lifetime tech support on items purchased from us.

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.
