Many cars come with factory speakers that fail to deliver a heart-pumping audio experience. If you’re an audiophile, you need a set of quality speakers that ignite your auditory senses. Great music can enhance your life—and your drives.
A good set of aftermarket speakers can make a huge difference in the quality of sound. They can produce detailed, clear, and dynamic audio. But finding speakers of good quality means separating the best from the rest. This guide takes a look at some of the best 6 3/4 speakers on the market. We’ve carefully examined each one for sound quality, aesthetics, and build.
The Best 6 3/4 Speakers
An audiophile’s dream, these speakers have a simplistic approach to aesthetics. However, what they lack in looks they make up for with high-quality, clear sound output—even at high volumes. Their circular frameworks in their favor as they can fit in most car speaker compartments. Instead of screw holes, they feature slots you can adjust during installation for a better fit.
The piezoelectric (PEI) dome tweeters deliver sharp, clear sound. You’ll be hard-pressed to find bass as defined as that of the Rocksford Fosgate P1675. The injection-molded, mineral-filled polypropylene cones and butyl rubber surrounds work together with the tweeters to provide accurate frequency reproduction. Integrated Concealed Crossovers (ICCs) do away with the need to mount black boxes to hold the speakers.

Best 6 3/4 Speakers Buying Guide & FAQ
Car manufacturers include basic speakers in their cars as part of their audio systems. However, most times, these car speakers don’t perform as well as aftermarket systems. That’s why you may want to replace them with new speakers at some point.
Your car’s sound system and speakers don’t have to be from your car manufacturer. However, compatibility is important when you are upgrading your car’s audio system. Aftermarket speakers offer great performance when paired with components such as amplifiers.
When you know what to look for, you can get speakers that will boost your car’s sound quality. Choosing the wrong speakers can cost you both money and time.
Do You Need a 6 3/4 Speaker?
Car speakers come in a range of sizes. The sizes may determine the sound you experience and the modifications you have to make to your car. The size of 6 3/4 speakers makes them a great replacement option for many factory speakers.
6 3/4 speakers may require minimal modifications during installation. Some cars come with 6.5 speakers, so you may have an easy time installing your new speakers. 6 3/4 speakers have a depth starting from two inches, so they don’t interfere with car parts such as windows and door locks.
The main reason you need to invest in 6 3/4 speakers is the sound output. Most speakers in this range have high-quality components and produce a well-balanced sound. The cones deliver powerful highs and mids, while the tweeters do an excellent job of supplying crisp highs.
- They have polypropylene cones, butyl rubber surrounds, and silk dome tweeters for awesome sound.
- They are affordable and are mostly sold in pairs, saving you money.
- You can pair 6 3/4 speakers with most amplifiers since they can handle varying degrees of power.
The Most Common Types of 6 3/4 Speakers
Speakers are differentiated by their construction and components. 6 3/4 speakers are divided into two categories: coaxial and component. Car manufacturers like to install coaxial speakers to keep costs low because sound isn’t one of their priorities when they are making cars. Your needs and budget should determine the speakers you get.
- Coaxial Speakers
Coaxial speakers offer a full range of sound as they feature various sound components. A two-way coaxial speaker has a woofer and a tweeter. A three-way speaker includes a midrange driver or a super-tweeter.
Coaxial speakers have frequencies starting from 20 Hz to 20 kHz. This wide range allows them to deliver good bass, mids, and treble. Their ability to produce quality sound even with low power makes them suitable for use with many factory stereos.
Coaxial speakers have sensitivity ratings as high as 91 dB and are very good at converting power into decibels. When paired with an amplifier, they produce awesome sound. Even speakers with low sensitivity ratings—like 88 dB—give an impressive performance.
- Component Speakers
Audiophiles usually install component speakers when they want to enhance a particular sound. Component speakers have two tweeters, two woofers, and two external crossovers. All of these are designed to work together to produce superb sound. When installing the speakers, you can install the tweeters separately for optimal imaging.
Tweeters typically deliver frequencies starting from 2 kHz. Their frequencies can reach 20 kHz, and they are responsible for a rich audio experience. Woofers have a frequency range of 20 to 200 Hz and are specifically designed to reproduce low and mid-range frequencies well. Crossovers are responsible for creating different sound frequencies: highs, lows, and mids.
What to Consider When Buying 6 3/4 Speakers
There are many things that can guide you when you’re shopping for speakers. For example, you can choose car speakers based on brand, price, sensitivity, or power handling. It is also important to remember that each speaker feature has a different impact on sound fidelity. The following are some of the most important features you need to check before getting a 6 3/4 speaker system.
- Components and Material
No question about it: the components used to make the speaker play a big role in audio quality. The best 6.75” speakers are made using vacuum or injection-molded polypropylene. Polypropylene is a stiff yet flexible material that maintains its rigidity even when rendering bass. Butyl rubber is also a common feature in many 6 3/4 speakers. This material enhances the surround and improves a speaker’s lifespan.
Tweeters can be made from soft materials such as silk or tough ones such as aluminum. Silk dome tweeters deliver smooth mids and highs. However, if you want livelier highs, go for tweeters made from solid materials such as aluminum or metal.
- Power Handling
All car speakers need a power source to work. The lower power handling rating indicates the minimum wattage the speaker needs to produce acceptable sound. The higher rating indicates the maximum wattage the speaker can handle for a prolonged period. For the best results, you should match the RMS of your power source to the higher end of the speaker’s RMS.
Some speakers can handle up to 200 W from an amplifier. However, be careful not to overpower your speakers. If the speaker cannot handle the power input, it will start to distort the sound—which is the last thing you want.
- Sensitivity
Sensitivity refers to the sound output you get from your speakers when you power them. Some coaxial speakers have low sensitivity. These are okay if you’re not one to push audio boundaries and prefer to play music at a low or neutral volume. However, if you are looking to play music at its loudest, get a speaker with a high sensitivity rating, such as 90 dB.
It is worth noting that a speaker’s sensitivity can be affected by factors such as the audio system. This is because the output usually matches the source of the audio. If the car audio system has weak output, high sensitivity won’t count for much. You can install a high-performance car audio system to steer clear of that problem.
Tips for Buying and Using 6 3/4 Speakers
If you fail to plan, you plan to fail. Car speakers are a big investment, so you shouldn’t buy them blindly. There are a few things you can do to ensure you get the best speakers for your car. Afterward, you can optimize the speakers for the best audio experience.
When shopping for 6 3/4 speakers, consider your budget, the speakers’ features, the warranty, and how easy they are to install. Coaxial speakers are easier to install as they don’t have many separate components.
After you install the speakers, be sure to play high-quality music files for the best sound reproduction. Also, ensure you don’t play the music at very high volumes as it may damage your hearing. Here are some additional tips for using your speakers:
- Install noise deadeners, especially in the doors where the sound is likely to rattle.
- If you want to enhance the effect of highs, try angling the tweeter towards you.
- Invest in a good amplifier and subwoofer box if you want to boost the bass without distorting the sound.
