  • Frequency Range: 52 Hz - 20 kHz

Rockford Fosgate's R165X3 is our best overall product in this 6.5-inch car speaker review because it is a 3-way full-range system that comes at a very reasonable price.

The pair generates sound using a woofer, a silk-dome Piezo tweeter, and a midrange. This gives you a balanced output with low frequency, high frequency, and mid-frequency sounds.

On top of this, the unit features a rubber surround and a vacuum polypropylene cone that does not absorb moisture. As such, you get very low sound distortion.

A high-pass crossover is built-in to prevent bass and midrange frequencies from being sent to the tweeter, which helps to enhance the sound quality.

Overall, the system has a power handling of 45W RMS, which gives you a decent sound and does not require an external amplifier. At 91 dB, the set is also very loud. A stamped steel basket and grille make the speakers look as good as they sound.

That said, if you want a full set for your car, check out the 4-piece Rockford Fosgate R165X3. However, both options lack a low-pass crossover to prevent high and mid-range frequencies from being sent to the woofer.

Pros

  • 3-way full-range system
  • Reasonably priced
  • Low sound distortion
  • Integrated high pass filter
  • Stamped steel basket and grill

Cons

Pioneer TS-A1670F
  • Power Handling: 70W RMS, 320W Peak
  • Sensitivity: 87 dB
  • Frequency Range: 37 Hz - 24 kHz

With its multilayer mica matrix cone design, the TS-A1670F gives optimum sound reproduction and responsiveness, making it one of the best 6.5-inch car speakers for clarity. It disperses the sound widely while also delivering a deeper bass with low frequencies of up to 37 Hz.

That said, the product is a 3-way set of speakers that contain a woofer, a 1.625-inch cellulose fiber cone midrange, and an 11mm polyethylene terephthalate hard dome tweeter that has a high-frequency output of 24 kHz. These have a power handling of 70W RMS, which enables them to deliver clear, balanced sound.

The tweeter optimizes sound at higher volumes because it delivers an improved range of mid to high range frequencies.

An elastic lightweight polymer surround is built-in to allow the cone to vibrate more freely and alphasonic earbuds are included as accessories. The only issue is that the set is not very loud because it has a sensitivity rating of 87 decibels.

Pros

  • Multilayer mica matrix cone
  • Deep 37 Hz bass
  • 3-way full-range system
  • High-volume optimized tweeter
  • Alphasonic earbuds accessories

Cons

  • Not very sensitive

5. Best for Smooth Sound: Pyle PL63BL

Pyle PL63BL
Pyle PL63BL
  • Power Handling: 180W RMS, 360W Peak
  • Sensitivity: 89 dB
  • Frequency Range: 90 Hz - 20 kHz

A combination of a high 180W RMS rating and a 3-way full-range system ensures the Pyle PL63BL gives you a smooth, detailed sound.

This system includes a 1-inch neodymium film dome midrange and a 0.75-inch Piezo tweeter, which combine forces with the stiff, eye-catching blue-poly injection cone to make this one of the best sounding 6.5-inch speakers.

That said, the cone is held in place by a non-fatiguing butyl rubber surround that is durable enough to withstand sunlight, extreme temperatures, and moisture.

The speaker has a 20-oz magnet structure, which has a durable voice coil that can handle high temperatures and fatigue to ensure low sound distortion.

A low-impedance 4-ohm component system compensates for the undersized wire found in most cars, while also making the most of the 360W peak power.

Grills and mounting hardware are included, but with a 90 Hz minimum frequency though, this set of speakers does not produce very deep bass.

Pros

  • 3-way system with a high RMS rating
  • Non-fatiguing butyl rubber surround
  • Durable voice coil
  • Low 4-ohm impedance system
  • Grills and mounting hardware

Cons

  • Bass is not very deep

  • Frequency Range: 35 Hz - 22 kHz

JVC's CS-J620 is fitted with hybrid surround materials (rubber and cloth), which give good movement, and support the lightweight Mica Injected Polypropylene (MIPP) cone. Overall, these two components move more air to create a deep bass with a low 35 Hz frequency minimum.

That said, the speakers are a 2-way coaxial type, and have a ferrite-magnet as part of the woofer. The second component is a neodymium magnet tweeter that is shallow-mounted with a 1-inch poly-ether balanced dome.

Another benefit you get with this 2-piece set is that they are engineered for easy installation. They have a shallow 1.8125-inch frame that won't hit the window track or glass in the door panel. Pre-arranged hole patterns are also drilled through the frame's rim to fit in most vehicles, making it one of the best 6.5-inch door speakers.

Mounting screws and tabs are included for installation purposes, as well as wire extension cables with quick disconnects. On the downside, the product has a low RMS rating of 30W, which means you may get distorted sound. Also, there's no midrange.

Pros

  • Flexible hybrid surround materials
  • Deep bass 35 Hz woofer
  • Easy to install
  • Includes mounting screws and tabs
  • Wire extension cables with quick disconnects

Cons

  • Might produce distorted sound
  • No midrange

  • Power Handling: 100W RMS, 300W Peak
  • Sensitivity: 92 dB
  • Frequency Range: 40 Hz - 22 kHz

With its marine-certified (IP55) polypropylene cone and waterproof rubber surround, Polk Audio' DB652 can withstand harsh environments in your car. Additionally, the cone is UV tolerant, which makes the speakers ideal to use in other vehicles such as boats.

The product comes as a set of two speakers, and each has a removable sport grille that you can use to customize its look.

Dynamic balancing technology is built-in to deliver signature sound quality, which is further enhanced by its high 100W RMS rating. This gives you a smooth, undistorted sound, but you might need to add-on an extra amp to provide sufficient power.

A 0.75-inch silk-dome tweeter is included to deliver smooth highs, while a built-in crossover keeps the low and high frequencies flowing to the right drivers. That said, you don't get a midrange driver to give a smooth output of the medium frequencies.

Pros

  • Waterproof, marine-certified, and UV tolerant
  • Removable sport grille
  • Dynamic balancing technology
  • High 100W RMS rating
  • Built-in crossover

How to Buy the Best 6.5-inch Car Speaker

How To Buy The Best 6.5-inch Car Speakers

1. Coaxial vs. Component Car Speaker

Coaxial speakers are 2-way or 3-way speakers that have all the components (woofer, tweeter, midrange, and crossover) in one piece. They are more compact and are ideal if you have limited space in your car.

Read More: 2-way vs. 3-way Speakers

On the other hand, component speakers come as separate pieces. These take up more space and can be difficult to install, but they give you better sound quality. They usually have a larger, more effective crossover that distributes the frequencies more efficiently to each driver.

2. Power Handling

Power handling is a measure that shows how much power a speaker can handle. Measured in watts, this factor is usually given in RMS and peak values.

RMS shows the amount of power the speaker handles continuously. However, peak rating indicates the power that the unit can withstand in short bursts.

Peak power is always higher than RMS, but it is more important to consider the RMS value because this is the continuous power handling.

That said, a high RMS rating means the speaker produces clear sound with no distortions and is more reliable over time. We highly recommend this, even though you might have to add-on an amplifier to supply enough power.

With that in mind, 30W is good enough, but 50W and above is better. However, any rating above 100W is best.

3. Sensitivity

This is a measure of the sound level (volume) produced by a speaker from the power fed to it. Given in decibels, a rating of about 84 - 88 dB is average, but we recommend above 90 dB. You should not buy any speaker with a sensitivity below 84 dB because this will perform poorly.

4. Frequency Range

The frequency range shows the frequencies that the speaker emits and is measured in Hz or kHz. That said, the wider the range, the better because this means you get low frequencies for bass and highs for the tweeter. This will give you a more balanced sound.

In this case, you should check out Kenwood KFC-1666S, which has a wide 35 Hz - 22 kHz range.

5. Material

It is important to consider the cone's material for durability and sound quality purposes. This section should be water and UV resistant so that it withstands the harsh hot and humid environment in your car.

Aside from that, it should be large and flexible so that it pushes a lot of air to create more bass. The surround should also be flexible to give the cone more room to move.

Conclusion

As you can see, Rockford Fosgate's R165X3 is our best of the best 6.5-inch car speaker because it has a reasonably priced full-range 3-way system. It offers low sound distortion and has a built-in high pass crossover.

If you don't mind spending though, we recommend JBL's GTO629 because it has large cones for bass and dedicated crossovers for directing the high and low frequencies to the respective drivers.

For the best full-range speakers though, you should check out Boss Audio Systems' CH6530. The product has a powerful 150W peak 3-way system, a durable high-temperature voice coil, and an overload-resistant Piezoelectric tweeter.
