In-Depth Reviews: 7 Best 6.75 Car Speakers

Now, We will be knowing the best and worst of our hand-picked best 6 ¾ car speakers.

1. Best Overall: Rockford Fosgate Punch P1675 Car Speaker

Rockford Fosgate Punch P1675 Coaxial Speaker
Item Specifications:
  • Speaker Type: 3-way coaxial
  • Sensitivity: 88 dB
  • RMS Power Handling: 55 watts
  • Peak Power Handling: 110 watts
  • Frequency: 65Hz-22kHz
  • Nominal Impedance: 4-Ohm
  • Grille Includes: Yes
  • Crossover: Built-in tweeter crossover

Robust, powerful, and clear sound. If you are searching for these and have space issues in your vehicle, there can not be a better alternative than the Rockford Fosgate Punch P1675.

It is a 3-way coaxial speaker, including a polyetherimide (PEI) dome tweeter and super tweeter, offering a compact installation. The FlexFit basket design and Multi-OEM Adapter make these speakers adaptable to a variety of car models and head units. So, you will not need to make an initial investment to upgrade your factory system.

The P1675 speakers feature a polypropylene cone and a butyl rubber surround. These materials not only ensure durability but also contribute to superior sound quality. The speakers' innovative Vertical Attach Surround Technique (VAST™) increases the cone area by up to 25%, enhancing sound output and performance.

Ease of installation is a significant advantage. The speakers come with adapter brackets for various sizes (5"x7", 6"x8", or 6"x9"). However, there is a need for additional modifications in certain car models. It's worth noting that the oversized terminals may not connect to a standard wiring harness, but a solution is provided with the inclusion of a free 10-pack of female quick slides.

Though the enhanced clarity allows listeners to enjoy nuanced details in music, without an amplifier, you will not get the deep bass vibe. Another noteworthy problem we found is the lack of certain installation components in the package. So, check before you buy.

The speaker is worthy of deeming itself the best 6.75 coaxial car speaker with its customer-favorite features. While there are a few challenges in terms of installation and bass performance, the overall value and sound quality they offer make them a worthy investment.



2. Best Reliable: KICKER 46CSC674 6-¾" Car Speaker

KICKER 46CSC674 6-¾ Car Speaker
Item Specifications:
  • Speaker Type: 2-way coaxial
  • Sensitivity: 90 dB
  • RMS Power Handling: 100 watts
  • Peak Power Handling: 300 watts
  • Frequency: 40Hz-20kHz
  • DC Resistance: 3.3-Ohm
  • Grille Includes: Yes 

Want a 6.75 speaker for your car that offers endurance and durability? We present you with one of the most resilient speakers of the year–the Kicker CS-Series CSC67 Coaxial Speakers. Someone who values durability in car speakers will be excited to try them. This pair is a standout choice for anyone looking for a reliable upgrade from standard factory speakers.

What sets them apart from your current stock speakers? They have a heavy-duty motor and magnet structure. Also, With a polypropylene woofer and Extended Voice Coil (EVC™) technology, these speakers deliver ultra-clean bass and impeccable sonic quality.

The zero-protrusion PEI tweeters feature neodymium magnets that enhance clarity without interfering with factory grilles. You will have excellent sound quality with clear mids and highs, and they will give you far better musical beats than your OEM Ones.

There is more to it. The low-profile tweeters and UV-treated poly-foam surround make them adaptable to various settings and resistant to heat and sunlight. It has steel mesh grilles to ensure longevity. However, a few have experienced problems with the foam deteriorating over time without any significant hazards.

One of the key pros of these speakers is their ease of installation. Even less technically inclined people can install them with proper tools and adaptors.

One of the key concerns our team noticed is that they produce distorted sounds at maximum volume. You will have to solve the problem by adding high-end subs and amps.

If you are ready to neglect those minor drawbacks, then you should definitely keep them on your wishlist. You should also check the component version, which offers in-line crossovers and a separate tweeter.



3. Best for Mids: Rockford Fosgate Punch P1675-S

Rockford Fosgate Punch P1675-S Component Speaker
Item Specifications:
  • Speaker Type: 2-way component
  • Sensitivity: 89 dB
  • RMS Power Handling: 60 watts
  • Peak Power Handling: 120 watts
  • Frequency: 55Hz-22kHz
  • Nominal Impedance: 4-Ohm
  • Grille Includes: Yes

The Rockford Fosgate Punch P1675-S component speaker is the current favorite car component speaker of the year. They have an amazing aesthetic and produce awesome beats with their surround sound technology.

The component set includes two 6-3/4" woofers, having the finest of a robust polypropylene cone and butyl rubber surround. Even during extended periods of high-volume usage, this combination ensures durability and resilience. Along with that, you will also get two 1" PEI dome tweeters to handle the intensity of heavy bass.

The speakers have an increased cone area of 25% to give you a fuller sound. If you have the Fosgate P165-S, you will not need a separate crossover box. They have an Integrated Concealed Crossover (ICC) within the speaker frame that simplifies installation and enhances aesthetics. The FlexFit Basket design with slot-mounted frame further adds to the simpler installation procedure.

Users, even music professionals, frequently praise the powerful sound quality of the Punch P1675-S. The clarity in highs, balanced mids, and crisp lows contribute to a listening experience that is bound to surpass factory-installed speakers. The compatibility with various vehicles, including popular models like Jeep Wrangler, VW Jetta, and Honda Accord, is a significant advantage.

We have noted that the speakers can be overly bright, with the highs occasionally coming across as sharp or "tinny." This might necessitate adjustments to the treble settings. While the bass performance is adequate for many, it may not satisfy those seeking a deep, thumping bass experience without the support of additional subwoofers.

These speakers offer excellent value for their price and provide premium sound quality at a reasonable cost. You won't regret installing them in your setup, as they are already dominating the consumer space as the ultimate 6.75 component speaker.



4. Best for Highs: HERTZ UNO Series K-170

HERTZ UNO Series K-170 Component Speaker
Item Specifications:
  • Speaker Type: 2-way component
  • Sensitivity: 93.5 dB
  • RMS Power Handling: 70 watts
  • Peak Power Handling: 280 watts
  • Frequency: 55Hz-23kHz
  • Impedance: 4-Ohm
  • Grille Includes: Yes
  • Crossover: integrated with tweeter 6 dB/Oct

Are you considering upgrading your car to produce the best highs? The Hertz UNO Series K-170 is what you're looking for. This 6.75" component speaker system, known for its blend of quality and performance, offers a notable jump to the higher spectrum of the audio band.

One of the standout features of the UNO K-170 is its sound clarity, largely thanks to the 24mm diaphragm Neodymium tweeter with a PEI dome optimized for high-frequency reproduction. To ensure a crisp and clear audio experience, the annular acoustic lens also contributes to the extraordinary off-axis performance.

If you're someone who shies away from complicated DIY projects, you'll be pleased with the Hertz UNO and its ease of installation. The speakers come with external and embedded mounting accessories to cater to different installation preferences. They are suitable for car setups that require reduced-depth speakers, making them a versatile option for audiophiles who deal with space constraints in their vehicles.

While the system delivers on high frequencies, we noticed a significant reduction in bass after installation. It impedes the enjoyment of a fuller sound profile. The V-cone design, intended for a clear mid-high frequency detail and powerful bass, seems to underperform in some cases.

Its performance in low frequencies and the inconsistency across different vehicle models are points to consider. If you value high-frequency clarity and are working within specific space constraints, this system could be a great value to your vehicle.



5. Best for Surround Sound: Kenwood KFC-1796PS 6-¾"

Kenwood KFC-1796PS 2-way Coaxial Speaker
Item Specifications:
  • Speaker Type: 2-way Coaxial

Thanks to Kenwood's proprietary Sound Field Enhancer, you're guaranteed a broader and more immersive sound field in frequencies above 5kHz.

To improve the transition to higher frequencies, they have an Acoustic Sound Harmonizer utilizing strategically placed slots in the tweeter mount. The new woofer damper shape and frame design contribute to a more responsive bass and cleaner overall sound.

The speakers remarkably minimize distortion using a polypropylene cone with a unique diamond array pattern. This technology, coupled with a robust rubber surround, ensures durability and consistently high-quality sound output. 

With a peak power of 330W and a sensitivity of 88 dB, these speakers are not just about sound quality; they're also about efficiency. The design is thoughtfully tailored to fit most factory speaker locations, a feature underscored by the low-profile tweeter design. This 'Factory Location Fit' makes them a versatile choice for a wide range of car models.

While the speakers fare well in most respects, there are a few considerations to bear in mind. For certain car models, minor modifications, like adding a spacer, might be necessary. It's also worth noting that these speakers, though a significant upgrade from stock ones, don't quite reach the pinnacle of high-end audio systems. 

The Kenwood KFC-1796PS speakers are an excellent choice for those looking to enhance their car's audio system without breaking the bank. While they have a few limitations, these do not significantly detract from their overall value and performance.

Should I Install My Own Car Speakers?

You may install your own car speakers depending on the technicalities involved. If you are only a beginner, we advise you to do it under someone’s supervision. That can be your friend or anyone else, but the person should have previous experience.

What is the Sensitivity of the Car Speakers?

The sensitivity of car speakers measures how efficiently they convert power into sound, expressed in decibels (dB) per watt from one meter away. Ratings typically range from about 85 dB (low sensitivity, requiring more power for high volume) to over 100 dB (high sensitivity, needing less power for the same volume).

Speakers with a sensitivity of 89 dB to 92 dB are suitable for most car audio systems, offering a balance between power needs and volume output. This specification is crucial when matching speakers with your car's amplifier to ensure optimal sound performance without overextending the audio system's power capabilities.

How Much Power Do I Need for My Car Speakers?

You need speakers that match the RMS (Root Mean Square) power output of your car's stereo or amplifier for optimal sound. Speakers with a higher RMS rating than the stereo can handle more power but may not perform at their best without adequate power.

How Do I Match Speakers with My Car Stereo?

Match speakers to your car stereo by comparing their RMS power ratings and impedance (ohms). Ensure the speakers’ RMS power is close to or slightly above the stereo’s output and their impedance matches to avoid distortion and achieve the best sound quality.

How Do Weather and Temperature Affect Car Speakers?

Extreme temperatures and humidity can damage car speakers by affecting materials like the surround and cone. Heat can degrade materials, while cold makes them brittle. High humidity can cause moisture buildup, leading to corrosion. Choose speakers designed for your climate for longevity and performance.
