Hertz HSP2-14 Harley Audio Upgrade Kit for 2014–2023 Street Glide & Road Glide | Stage 2 Amplifier & Speaker System

If you're upgrading your 2014–2023 Harley Davidson Street Glide or Road Glide and want more volume, better clarity, and stronger performance than a basic upgrade, the Hertz HSP2-14 Stage 2 audio system is the perfect next step.

This system builds on a standard speaker upgrade by increasing amplifier power and improving overall system efficiency, giving riders the ability to hear their music clearly at highway speeds without jumping into a full multi-speaker system.

If your current setup still isn’t loud enough or lacks clarity while riding, this Stage 2 upgrade delivers the performance you're looking for.

This kit is designed for:

• 2014–2023 Harley Davidson Street Glide

What’s Included in the Hertz HSP2-14 Kit
