Hertz is one of the few audio brands building speakers with mounting holes and terminals specifically matched to Harley-Davidson fairings and saddlebags, rather than relying on generic adapter rings. Since the topic is specifically Hertz gear, this list covers Hertz’s actual current speaker and sound-pack lineup for Harley rather than mixing in other brands.

Buying tips
- Match the kit to what you’re replacing: HSP1 is front-fairing only, HSP2/HSP3 add saddlebag speakers for fuller sound on longer rides.
- The SP 4.900 amp is IP55-rated for weather resistance — don’t substitute a car amplifier not rated for open-air/vibration use.
- Confirm your Harley’s model year against each kit’s compatibility list before buying — several of these are sold as year-specific packages, not universal fits.
