Hertz HSP2-13 Harley Audio Upgrade Kit for 1998–2013 Street Glide & Road Glide | Stage 2 Amplifier & Speaker System

If you're upgrading your 1998–2013 Harley Davidson Street Glide or Road Glide and want louder, cleaner sound at highway speeds without building a full multi-speaker system, the Hertz HSP2-13 Stage 2 audio kit is the perfect next-level upgrade.

This system builds on a basic front speaker upgrade by adding more power, better efficiency, and improved clarity, making it ideal for riders who want serious performance without jumping into a full bagger audio system.

If your current setup still struggles at speed or lacks volume, this Stage 2 upgrade delivers the power and clarity needed to ride and actually hear your music.

Fits 1998–2013 Harley Davidson Touring Models

This kit is designed for:

• 1998–2013 Harley Davidson Street Glide
• 1998–2013 Harley Davidson Road Glide
• Batwing and Sharknose fairing speaker locations
• Factory radio integration

Plug-and-play design simplifies installation while maintaining clean factory integration.

What’s Included in the Hertz HSP2-13 Kit

This Stage 2 system is engineered as a matched upgrade for improved performance:

• Hertz Amplifier (High-Output Motorcycle Amp) – increases system power for higher volume and cleaner sound
• Hertz 6.5" Motorcycle Speakers (Front Fairing) – designed for clarity and output in open-air riding
• Plug-and-Play T-Harness – allows installation without cutting factory wiring
• Mounting Hardware & Integration Components – ensures proper fitment and clean install

Each component is designed to work together to deliver balanced output and improved performance over entry-level upgrades.
