Available at approximately $20 per speaker, the Pyle PL683BL 6×8 speakers offer remarkable sound quality within their budget-friendly price range.

In traditional designs, speakers often use a center-driven approach. However, the Pyle PL683BL speakers use an edge-driven design, resulting in a smoother, less rattled sound quality even at higher volumes. This means you can enjoy loud music without worrying about distortion or unpleasant highs.

The Plus One woofer cone architecture is another feature that sets these speakers apart. These patented cones provide more speaker-cone area than most other speakers in the same class. This results in increased volume range, lower bass range, and a more dynamic overall audio experience.

While the value for money is excellent, the most common critique of these speakers is their inability to match the performance of pricier models. If you want the highest quality audio, you may need to consider adjusting your budget.

How to Pick the Best 6×8 Speakers: Step-by-Step

When choosing a 6×8 speaker, there are four main considerations for most buyers. 

  • Sound quality
  • Power handling
  • Build quality
  • Warranty

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

Sound Quality

Sound quality is the most important factor when choosing 6×8 speakers for your car’s audio system. It directly impacts your listening experience as it determines how accurately and clearly the speakers reproduce audio.

When evaluating sound quality, look for 6×8 speakers that offer a wide frequency range. Prioritize speakers with durable materials and advanced tweeter designs for precise sound reproduction. Additionally, we recommend reading user reviews to verify the sound quality of your chosen model.

Power Handling

It’s important to understand power handling to prevent damage to your 6×8 speakers when listening at high volumes. While it’s typically expressed in two ways (continuous power handling and peak power handling), continuous power handling is more important to consider.

Look for speakers with high continuous power handling ratings, measured in RMS, as they indicate the speaker’s ability to manage sustained power levels. As a general guideline, a continuous power handling rating of around 50 to 75 watts RMS is often considered an adequate choice for typical car audio setups. This rating allows for clear sound at moderate to high volumes.

Build Quality

The build quality of 6×8 speakers directly affects their longevity and ability to withstand the rigors of a car’s environment. It’s essential to choose speakers with durable materials that can endure temperature fluctuations, humidity, and exposure to dust and debris.

We recommend looking for speakers with sturdy rubber surrounds that support the cone’s movement. High-quality materials, such as rubber and polypropylene, are known for their durability. If you’re not able to inspect the speakers before you buy, take care to read customer reviews to verify their quality.


A warranty is your safety net, providing you with peace of mind in case of any unexpected issues or defects with your 6×8 speakers. When selecting speakers, consider the length of the warranty provided by the manufacturer. A more extended warranty period often indicates the manufacturer’s confidence in the product’s quality and reliability.

It’s also a good idea to understand what the warranty covers, including components, labor, and potential shipping costs. Knowing the warranty terms and having access to responsive customer support can save you from unexpected costs down the road.

Upgrading your car’s speakers can enhance your quality of life.

What to Know Before Buying 6×8 Speakers


One of the primary factors to consider when purchasing a 6×8 speaker is compatibility. You need to ensure that the speakers you choose are a suitable fit for your car’s audio system. This step is crucial to avoid the frustration of purchasing speakers that won’t fit or require extensive alterations.

To ensure compatibility, we recommend using a site like Crutchfield to determine what kind of speakers can be installed in your car. Once you enter your car’s details, you can verify that your chosen option will fit either with or without modifications.

Preference on Sound Balance

Before making a selection, consider what kind of audio experience you desire. Do you lean towards clear high frequencies or do you prefer deep bass tones? Alternatively, you may be looking for a well-balanced, all-around sound.

Understanding your preferred sound profile will guide your choice. While some speakers can provide both deep base and high treble, many speakers tend to excel at only specific aspects of sound reproduction.

End Goals

After determining what 6×8 speakers will fit in your car, you need to figure out what your objectives are. Are you simply trying to replace a blown speaker? In this case, your goal might be to find a budget-friendly option that matches or exceeds the factory specifications.

However, if you are aiming to build a high-quality sound system from scratch, you’ll need to consider factors like sound quality, build quality, and power handling.

By defining your end goals, you can select the 6×8 speaker that best aligns with your needs.

Number of Speakers Included

If you’re buying 6×8 speakers for the first time, you should know that they typically come in pairs. This allows you to enhance your car audio with both left and right speakers for a balanced sound experience.

Before buying 6×8 speakers, take care to confirm the number of speakers included in your purchase. This will ensure that you don’t accidentally purchase too many or too few for your needs.

For a louder speaker, prioritize models with high speaker sensitivity ratings.

Using 6×8 Speakers: What It’s Like

After you upgrade your car’s sound system, the first thing you will notice is the clarity of the sound. Old songs will sound like you’re hearing them for the first time. You’ll start noticing details you’ve never heard before. Subtle guitar strings, background vocals, or even the artist’s breath between verses become apparent.

With a good sound system, you feel immersed in the music. The sound surrounds you, making you feel like you’re in the middle of a concert. If you enjoy bass-heavy music, you’ll love the sensation of deep, resonant bass that can literally make your car vibrate.

Frequently Asked Questions

How can I determine the right speaker size for my vehicle?

We recommend using online databases like Crutchfield which provides speaker compatibility information based on your car’s make and model.

It’s always a good idea to confirm the validity of the information you find by verifying it with other sources.

What does "speaker sensitivity" mean and why is it important?

Speaker sensitivity, measured in decibels (dB), indicates how efficiently a speaker converts power into sound. It determines a speaker’s ability to produce volume with a given power input. High sensitivity means louder sound with less power, making it both cost-effective and efficient.

What is the difference between continuous power handling and peak power?

Continuous power handling represents the maximum power a speaker can handle without damage over an extended period. Peak power is the highest power level a speaker can briefly withstand for short bursts without being damaged.

In general, continuous power handling is a more reliable measure of a speaker’s capabilities for everyday use.

Can I mix and match different brands of car speakers in my vehicle?

Yes. You can mix different brands of car speakers, but ensure they are compatible with your vehicle in terms of size and mounting. Mixing brands may slightly affect sound balance, so using the same brand or series for front and rear speakers is advisable.

What is the difference between a coaxial speaker and a triaxial speaker?

A coaxial speaker combines a woofer and a tweeter into a single unit. A triaxial speaker, on the other hand, adds an additional mid-range driver to the combination, providing enhanced sound performance and more balanced audio.

What are surrounds?

In the context of speakers, surrounds refer to the flexible, often rubber or foam, rings or edges that connect the speaker cone to the speaker frame. These surrounds allow the speaker cone to move back and forth while maintaining an airtight seal.

They are crucial for ensuring proper sound reproduction and preventing air leaks that can lead to distortion and loss of sound quality. 

What is speaker impedance and how does it affect sound quality?

Speaker impedance measures how power-hungry a device is. If your device has low impedance, it means it is drawing more power.

You need to be aware of impedance because a mismatch between a speaker and an amplifier will result in a dirty, distorted sound even if you have great speakers.
