Struggling to hear your factory Harley speakers at highway speeds?
We hear you. Many Harley Davidson owners face the same issue, battling with low sound quality and blown speakers. At Volunteer Audio, we’re dedicated to delivering a sound experience that will truly blow you away.

Can you really hear rear speakers when added to your bike?
Absolutely! Our customers frequently ask this, and we’re excited to confirm that rear speakers can indeed be heard clearly. Here’s how we make it possible:

• Optimal Speaker Positioning: For 6×9” speakers, we use custom cut-in kits that position the speakers higher in the lid, conserving space in your bag and angling the speaker towards you for better sound clarity.
• Proper Powering: We ensure rear speakers are powered adequately so that they are loud enough to be heard even from behind.
• Balanced Sound: While the front speakers will always be more direct and therefore louder, our rear speakers complement them, providing a richer, more immersive sound with added mid-bass and a concert-like experience.

Our Complete Audio Upgrade Package Includes:

• Pre-Wired SP4.900 Amplifier: Gains and filters adjusted perfectly for your factory Skyline OS Infotainment radio.
• Volunteer Audio HD-A2B Interface: Seamlessly integrates with your Harley Davidson.

  • 1 pair of Hertz SX165NEO 6.5” upper fairing speakers
  • 1 pair of Hertz SX690H NEO 6×9” saddlebag lid speakers
