Can you hear your factory Harley speakers loud and clear at highway speeds?
We didn’t think so.
Tired of blowing those factory speakers just trying to hear them?
Of course you are! These are common issues we hear ALL the time at Volunteer Audio. That’s why we’re here to deliver a sound experience that will truly blow you away.
Can you really hear rear speakers when added to your bike?
Absolutely! We get this question frequently, and the answer is a resounding YES. Here’s how we ensure you get the full benefit from your rear speakers:
- Optimal Speaker Positioning: For 6×9” speakers, we use custom cut-in kits that elevate the speakers higher in the lid. This not only saves space in your bag but also angles the speakers toward you, improving sound clarity. Most replacement lids don’t do this.
- Proper Powering: We make sure the rear speakers are properly powered so they’re loud enough to be heard even from behind.
- Balanced Sound: While front speakers will always be louder due to their direct orientation, rear speakers add a fuller, surround sound experience with enhanced mid-bass, creating a concert-like atmosphere.

- Pre-Wired Amplifier: Gains and filters are adjusted perfectly for your factory Skyline OS Infotainment radio.
- Volunteer Audio HD-A2B Interface: Seamlessly integrates with your Harley Davidson.
