Hertz Speakers Review

The following 4 reviews are meant to cover some of the most popular models from Hertz. Enjoy

​1. Hertz DCX 165.3

41qk oB2zNL. SL500

The Hertz DCX165.3 is an excellent option in terms of functionality and installation.

To top this off, the speakers’ minimalistic design is perfect to fit any car’s interior.


  • Sensitivity: : 93 dB
  • RMS: 60 Watts
  • Peak Power: 120 Watts
  • Frequency Response: 60-21,000 Hz
  • 2way/3way/4way: 2-way

You can install them yourself as they’re easy to fit.

They do have an average mounting depth of 2.5”, so keep space in mind before you start the process.

The speakers support high-pitched tones as well as low notes, thanks to the neodymium tweeter and PEI dome.

However, you won’t hear your very low bass notes as it only supports from 60Hz upwards.

You’ll love that there’s virtually no resonance, thanks to the thermoplastic polyurethane surrounds.


  • Excellent high frequency tones


  • Not all low frequency notes are powerful
  • The average mounting depth can cause space challenges

​2. Hertz HSK 165

These speakers have a reputation thanks to their clarity and power.

I chose them as the best 6.5 car speakers in my recent round-up list. Check that out too.​

This makes them an excellent option to upgrade an existing car audio system.

The low frequency support is limited, so consider adding a woofer if you’re in search of pumping bass sounds.


  • Sensitivity: 92 dB
  • RMS: 125 watts
  • Peak Power: 250 watts
  • Frequency Response: 50-22,000 Hz
  • 2way/3way/4way: 2-Way

Thanks to the neodymium REN tweeter you’ll get amazing high-frequency sounds.

These sounds are further enhanced by the silk used as part of the cone.

Some users say it might even be too sharp.

You may need a professional to tend to this, as it’s possible to tune the system to a correct setting so your ears will no longer get tired from these high pitches.

This speaker system incorporates tweeters, woofers, and crossovers.

If you’re installing them yourself, make sure you find space for all these components.

You have to build a protective box that houses all parts; therefore, this isn’t the easiest of systems to install.

The speaker offers a range of excellent features that improve its handling power and sound quality:

The bottom plate has vents and the cone contains fiber mesh, so your sound system is protected against overheating

A huge magnet is used which enhances the energy the speaker produces and increases the control


  • Excellent high frequency sounds
  • The speakers can handle a lot of power, so it’s safe to connect it to an amplifier


  • Low frequencies aren’t supported well
  • Some users need expert help with installation

3. Hertz HCX690

You’ll love these Hertz HCX690 speakers for their range and power.

You can push a lot of watts through these speakers without damaging them.

These speakers are so good, that I chose them as the best 6×9 car speakers.


  • Sensitivity: 94 dB
  • RMS: 130 Watts
  • Peak Power: 260 Watts
  • Frequency Response: 32-23,000 Hz
  • 2way/3way/4way: 3-Way

They also offer up excellent, clear sounds thanks to:

A vibration-proof magnet cover.

This prevents distortion of sounds.

The damped mesh fiber is used in the woofer component.

These amazing features can easily become part of your car’s sound system, because the HCX690 model is easy to install, as long as the oval shape doesn’t cause any hassle.

As long as you place them in safe compartments in your vehicle, these units won’t easily be damaged thanks to:

A die-cast aluminum basket that can withstand a lot of pressure and shock

The heat dissipation ability of all the components, so you don’t have to be concerned about the speakers overheating

When compared to other speakers of this type, you’ll love that low frequencies are supported; bass sounds from as low as 32 Hz can be heard through these speakers.

If you want even lower tones, you’ll need an additional woofer, but for the average music lover, this speaker should suffice.


  • Modern, stylish look
  • The speakers’ power handling is excellent, so it’s safe to connect it to an amplifier
  • Even without an amp, the sound is loud and clear


  • They aren’t the typical rounded shape.
  • The oval structure may not fit in many cars

4. Hertz MLK 1650.3

51pdOy2ysuL. SL500

The Hertz MLK 1650.3 speaker system easily achieves high dynamics and timbre while also boasting an extended frequency response, making it a welcomed addition to the vehicles of the most discerning of audiophiles. This component system includes two woofers, two tweeters, and two external crossovers along with grilles and mounting hardware.

  • Sensitivity: 92 dB
  • RMS: 150 watts
  • Peak Power: 300 watts
  • Frequency Response: 40 – 25,000 Hz
  • Impedance: 4 ohms
  • 2way/3way/4way: 2-way

The MLK 1650.3 is a 2-way system, meaning it includes both woofers and tweeters. The woofers feature 6.5” pressed-pulp V-cones with cotton fibers which deliver improved dispersion.

The Boundary Free rubber surrounds create an amazing low-frequency response and the aluminum alloy baskets feature built-in venting to accurately move air. The 1.43” tweeter has a low-distortion Tetolon dome.

Excellent damping reduces resonance and distortion for an accurate sound. Both the woofers and tweeters are powered by neodymium magnets, which are responsible for the high-pitched notes and low tones.

What really sets this already stunning setup apart is the crossover capability which allows for a bi-amplified system. By connecting two separate amplifiers (not included) it is possible to power the woofer and tweeter separately, allowing for increased power handling.

Two-position Mid-Contour and Hi-Contour settings allow for improved frequency response control. A Hi-Boost setting enables off-axis tweeter positioning and a 3-position attenuation tweeter switch allows for further customization.

This enables the system to be fine-tuned for optimal performance in various vehicle installations while also enabling you to achieve audio that sounds best to your ears.

Overall, the Hertz MLK 1650.3 speaker system delivers stunning range and power. The sound is rich and intense for a 2-way speaker. This setup may require a custom-built box for installation.

Every install is different, but a custom box has the potential to slightly complicate the installation process.


  • 1.43” Neodymium magnet tweeter with Tetolon dome.
  • 6.5” woofer with pressed-pulp cone with cotton fibers.
  • Crossover feature allows for separate amplification of the woofer and tweeter.
  • Mid-Contour, Hi-Contour, Hi-Boost, and a tweeter attenuation switch for customizing the sound.


  • As a 2-way system, this setup lacks a mid range. Both the woofers and tweeters are powered by neodymium magnets, which are responsible for the high-pitched notes and low tones.
  • May require a custom-built box for installation. While this will ultimately improve the sound quality it does add to the scope of the project.

Frequently asked questions

When it comes to speakers manufactured by Hertz, there are questions that arise more than once.

Are the Hertz Speakers worthwhile?
For this question,  we are going to say a straight-up yes. Why so? Although some of the speakers by this company are a bit pricey, they offer value for money. So whether you want to upgrade your vehicle’s sound system or want additional speakers for your car, then Hertz is the way to go. The sound system by Hertz delivers excellent sound if you’re willing to spend a little more bucks.

Are Hertz Speakers Better Than JBL? 
There are customers who love comparing these two brands, but the truth is, that the target market that JBL focuses on is different from what Hertz focuses on. This means it is quite challenging to compare the two as the speakers each company makes serve a different customer. Therefore, the question that you should ask yourself is what you want as a customer. In doing so, you will be able to determine which company will work best to satisfy your needs.

How Many Watts Should Car Speakers Be?
Customers also inquire how many watts car speakers should be. We recommend 200 to 300 watts of RMS power. There are people who want to add amplified speakers that assist in canceling out road noise, improving the clarity of sound. Therefore, the watts that you should plan on are 200 to 500 watts RMS. It would be best if you remembered that more watts indicate cleaner and louder speakers than an audio system with lower watts.

Are 2-way Speakers Better Than 3-way Speakers?
This question always concerns people who love good music in their cars, and we will say that if you’re working on a tight budget, then the 2-way speaker will work for you, whereas if you can spend a little more, then the 3-way speakers will give you high-quality sound.

Final thoughts

Hertz seldom disappoints. Reading through this review, I’m sure you can see how Hertz’s range of speakers offers something for every car owner.
