Hertz Vs Rockford Fosgate Motorcycle Speakers

Hertz Vs Rockford Fosgate Motorcycle Speakers

Loudness and Sensitivity Level

When it comes to loudness and sensitivity rating, we’d say Hertz gets a slight edge over Rockford, with a sensitivity level of 92 or more. On the other hand, Rockford probably has a better mid-range. So it turns out to be a pretty even competition considering the quality of highs and mids.

Power and Wattage

Wattage and the power handling capacity is an important considerations for motorcycle speakers. In this case, you’ll have more speakers from Hertz with a better peak power handling and RMS power handling rating. 

Power and Wattage

The power or more wattage is needed if you drive through downtowns or busy areas, but for the countryside and quiet areas, the lower wattage from either Hertz or Rockford should be fine. Speaker mounting location or engine noise could also impact your decision.

Mounting Options

If you’re upgrading the Harley stock speakers, you’ll mount a new speaker into the factory speaker location, either the lower or upper fairing. If you’re considering it to mount into the upper fairing, we’d suggest you go for Rockford as they’ve some perfectly suitable models.

Mounting Options

On the other hand, Hertz has some good lower-fairing models. You should go for Rockford for its wide range of mounting support for other bikes or mounting options like handlebars. Rockford is also compatible with rear speaker adapters.

Sound Quality

It’s difficult to say which plays the sound better, Hertz or Rockford. Both come with subwoofers, a wide range of frequency transmission, a surround sound system, etc. But Rockford could be a better choice for the quality of sound it provides in the price range.

Build Quality & Element-ready Features

Both these motorcycle speakers are well built and water-resistant. Since Rockford is a dedicated manufacturer of motorcycle speakers, it has included more element-ready features to withstand different outdoor elements and odd environmental conditions.

Hertz Or Rockford, Which One Should You Choose?

We’ve probably answered this question in the previous section, although here we can sum it up. There’s no doubt both of these brands make excellent 6.5 waterproof motorcycle speakers, which are the most sought among bikers. But the consideration comes into several other factors.

You should choose the Hertz speaker if you drive your motorcycle in a noisy area frequently because it deals better with noise distortion than its competitor. But you’ve to keep in mind that it’s a higher-end car audio manufacturer with mostly costly available options.

Hertz Or Rockford

But if you’re only planning to get a cost-effective upgrade for your Harley stock speakers, Rockford Fosgate remains a top choice for sure. Especially, for its excellent sound quality, build quality, and additional features.


It’s time to conclude things up here, and we must say it’s a very close call to choose between Hertz vs Rockford Fosgate motorcycle speakers. They both have their own pros and cons.

On the other hand, Hertz packs a punch with some of its premium models.
