Amplifier and Four Speaker Upgrade for 1998–2013 Street Glide & Road Glide with Tour-Pack Speakers

This motorcycle stereo upgrade replaces the factory front speakers, upgrades the rear Tour-Pack speakers, and adds dedicated amplifier power to dramatically improve sound clarity and volume while riding.

Many riders searching for a Harley Davidson stereo upgrade for Street Glide or Road Glide motorcycles quickly realize that replacing speakers alone will not solve the problem.

Who This Harley Stereo Upgrade Is Perfect For

The HSP2-13 system is ideal for riders who:

• ride long distances and want clearer music while cruising

For many touring riders, upgrading the stereo system is one of the most noticeable improvements they can make to their motorcycle.

What This Harley Touring Stereo Upgrade Improves

A motorcycle stereo upgrade like the HSP2-13 improves three important parts of the factory Harley audio system.

Front fairing speakers are replaced with Hertz SX-165-NEO 6.5-inch speakers designed for high output and clarity in motorcycle environments.

Rear Tour-Pack speakers are upgraded with Hertz SV-165-NEO speakers, which project sound toward the rider from behind.

The system is powered by the Hertz SP 4.900 compact motorcycle amplifier, delivering significantly more power than the stock Harley radio.

This combination allows the stereo system to produce louder, clearer sound while riding at highway speeds.

Harley Touring Audio System Layout

The HSP2-13 system creates a balanced motorcycle sound stage using both front and rear speakers.

Front stage
• upgraded fairing speakers for vocals and musical detail

Rear stage
• Tour-Pack speakers projecting sound toward the rider

Amplification
• four-channel motorcycle amplifier powering the entire system

This layout helps riders hear music clearly even when wind noise increases during highway riding.

Why Riders Upgrade Their Harley Davidson Stereo System

Factory Harley audio systems are designed for moderate listening levels, but wind noise often overwhelms the speakers once riding speeds increase.

Upgrading the stereo system with amplifier power and high-efficiency speakers can dramatically improve sound performance.

Riders typically experience:

• louder music while riding
• clearer vocals and instruments
• stronger midrange projection
• improved sound balance between front and rear speakers

Riders researching how to make Harley speakers louder, best Harley stereo upgrade, or Harley touring audio upgrade often start with amplifier-powered systems like the HSP2-13.

Frequently Asked Questions

Why can’t I hear my Harley stereo clearly while riding on the highway?

Most factory Harley audio systems struggle once wind, engine, and road noise increase at highway speeds. Upgrading to a system that includes a dedicated amplifier and higher-efficiency speakers allows music to project more clearly toward the rider, making it much easier to hear while cruising.

How much louder is this system compared to the factory Harley stereo?

The HSP2-13 system is significantly louder than the factory Harley audio system because it adds a dedicated four-channel amplifier along with high-efficiency motorcycle speakers. This combination provides stronger output and improved clarity while riding.

Is the Hertz HSP2-13 considered a Stage-2 Harley stereo upgrade?

Yes. The HSP2-13 system is generally considered a Stage-2 Harley audio upgrade because it adds amplifier power and upgrades both the front and rear speakers. Stage-2 systems provide a major improvement over factory audio while maintaining a relatively straightforward installation.

What is the difference between Stage-1, Stage-2, and Stage-3 Harley audio upgrades?

Stage-1 upgrades typically replace the factory speakers.
Stage-2 systems add amplifier power and upgraded speakers for much greater output and clarity.
Stage-3 systems expand the audio system even further with additional speakers such as saddlebag speakers or more advanced tuning components.

Will this system work with the factory Harley radio and controls?

Yes. The HSP2-13 system is designed to integrate with compatible Harley factory radios using the included wiring harness and amplifier integration components.

Do I need a Tour-Pack to install this system?

Yes. The HSP2-13 system is designed specifically for Harley touring motorcycles equipped with rear Tour-Pack speaker pods. If your motorcycle does not have Tour-Pack speakers, a different Harley audio system would be recommended.

Can this Harley stereo system be expanded later with additional upgrades?

Yes. Many Harley touring audio systems can be expanded with additional upgrades such as saddlebag speakers, digital signal processors (DSP), or additional amplification if you decide you want even more output later.

How long does a Harley stereo installation usually take?

Installation time depends on the motorcycle model and system configuration. Many Harley audio upgrades can be installed within a few hours, although larger systems with additional speakers may take longer.
