If you’re seeking best-in-class sound quality, few competitors can rival the Hertz HCX 165 6.5″ speakers.

These speakers offer a frequency response from 50Hz to 22kHz and can handle power from 100 to 200 watts. This means that you’ll get clear, lifelike sound even at high volumes.

The key to their high-quality sound lies in their oversized magnets and pure copper voice coils. The large magnets help the speaker move efficiently in response to electrical signals, while the copper voice coils reduce resistance, ensuring that the speaker accurately translates the audio signals it receives. This combination results in clearer and more powerful sound.

Furthermore, the tweeters have a rotary function that allows you to adjust directionality, so you can point the sound exactly where you need it. Due to this swivel function, the speakers come without grilles. While this allows you to adjust the direction of the speaker, it also leaves it vulnerable to accidental damage.

Another important consideration to acknowledge is that these speakers are more expensive than some other options. However, if you are looking for a truly exceptional sound experience, the investment may be worth it.

How to Pick the Best 6.5-Inch Speakers: Step-by-Step

When choosing a 6.5-inch speaker, there are three main considerations for most buyers. 

  • Sound quality
  • Power handling
  • Build quality

Let’s review each of these criteria in more detail.

Sound Quality

Sound quality is the cornerstone of your overall listening experience, as it directly influences your audio experience.

To assess sound quality effectively, keep an eye out for 6.5-inch speakers that provide a broad frequency range, are highly sensitive, and are crafted from quality materials. Additionally, to gain further insight into the sound quality of a particular model, we recommend checking user reviews, as they often provide valuable information from experienced users.

Power Handling

Understanding power handling is crucial to safeguard your 6.5-inch speakers from potential damage when enjoying high-volume audio. Power handling is typically expressed in two ways: continuous power handling and peak power handling. Of these, continuous power handling holds greater importance.

When shopping for speakers, seek those with robust continuous power handling ratings, which are measured in RMS (Root Mean Square). These ratings serve as an indicator of a speaker’s capability to handle sustained power levels.

As a rule of thumb, opting for speakers with a continuous power handling rating of approximately 50 to 75 watts RMS is commonly regarded as suitable for car audio setups. This range ensures that your speakers can produce clear and distortion-free sound, even when you’re cranking up the volume to moderate or high levels.

Build Quality

The build quality of 6.5-inch speakers determines how long they will last.

We recommend looking for speakers made of high-quality materials. This includes the speaker components such as the cone and surround, as well as the mounting hardware. Reading customer reviews can help you validate their quality and ensure they meet your expectations.

What to Know Before Buying 6.5-Inch Speakers

Bass Limitations

It’s important to be realistic about the capacity of 6.5-inch speakers to deliver strong bass. While they can provide decent mid-bass, their physical size and design limitations may restrict their ability to produce powerful low-end frequencies.

Therefore, when aiming for a fuller and more pronounced bass response in your car audio system, it’s advisable to prioritize sound clarity and sensitivity with your 6.5-inch speakers and consider complementing them with a dedicated subwoofer. This combination allows you to enjoy a well-balanced audio experience.


Not every 6.5-inch speaker will fit in every car. The compatibility of speakers with a specific car’s audio system depends on several factors, including mounting depth, hole size, speaker shape, and impedance.

Since it’s very difficult to confirm that each of these factors is compatible, we recommend using a site like Crutchfield to assess compatibility for you. This will help you avoid fit issues and the need for extensive modifications.

Preference on Sound Balance

Before you pick your speakers, think about what kind of sound you like. Do you want clear, high-pitched sounds, or are you all about that bass? Maybe you want a bit of everything.

Some speakers can do both bass and treble well, but most are better at one or the other. Knowing your sound preference will help you choose the right speakers for you.

Number of Speakers Included

6.5-inch speakers are typically sold in pairs because this allows you to create a balanced sound experience.

Before you buy, make sure to check how many speakers come in the package. This way, you won’t end up getting more speakers than you need, or worse, not enough for what you require.

Using 6.5-Inch Speakers: What It’s Like

When you add the perfect soundtrack, even sitting in bumper-to-bumper traffic can be an enjoyable experience. As your favorite tunes fill the car, the frustration of a slow-moving commute starts to fade away. You might find yourself singing along or simply enjoying the melodies as you find a temporary escape from the daily grind.

If you’re with friends, smiles and shared memories replace the typical annoyance of traffic congestion. It’s a reminder that the journey can be more important than the destination.

Frequently Asked Questions

Can you make cheap speakers sound better?

Yes, you can enhance the sound quality of inexpensive speakers by following a few strategies. First, it’s essential to choose a suitable location for your speakers. Proper placement can significantly improve sound quality, so experiment with different positions to find the best spot for optimal audio performance.

Additionally, consider adding an equalizer or inline capacitor to your setup. These devices can help balance the audio and make it more pleasing to the ear. Furthermore, incorporating an amplifier that matches your speakers’ impedance can also make a noticeable difference.

What should the midrange, treble, and base settings be?

While this depends on personal preference, we recommend setting your midrange to 0, your treble to +5, and your bass to +4.

What size speakers are best for cars?

While larger size doesn’t necessarily guarantee better sound quality, it’s true in many cases. You should aim to fill the size of your cavity to full capacity.

Is there any way to get more bass out of my 6.5" speakers?

The easiest way to get more bass is to add a subwoofer. However, if that’s not an option, you can also adjust your stereo’s equalizer to lean heavier towards bass.

What size hole do I need for a 6.5-inch speaker?

To accommodate a 6.5-inch speaker, you’ll typically need a mounting hole with a diameter of 5.5 inches. This size provides enough space for the speaker to fit securely and function effectively.

However, it’s essential to check the specific requirements of the speaker you plan to install, as there may be variations in hole size depending on the speaker’s design.
