The Buyer’s Guide to Choosing 6.5″ Component Speakers

Upgrading your vehicle’s speakers can be a hefty investment. Luckily, we’ve produced this short component speaker buying guide for you to review. You’ll be able to find the best car speakers for you.

Here you’ll find plenty of info including speaker terminology, what makes a good speaker, installation tips, and more.

What Is A Component Speaker?

Car manufacturers install full-range speakers as standard: these speakers are built with a single driver that handles all sound frequencies. As such, the low frequencies (bass) are often lost and larger full-range speakers fail to produce crisp higher frequencies as well.

A component speaker, on the other hand, is built up of several parts. 2-way component speakers have a woofer and a tweeter, handling low and high frequencies respectively. A crossover directs the frequencies into the appropriate component, ensuring a crisper, clearer sound quality all round.

What Makes a Good 6.5″ Component Speaker

Here’s what you should look for when researching component speakers for your vehicle

RMS Power Rating

Speakers will show a peak and RMS power rating. While a high peak rating is cool it doesn’t guarantee a high-end speaker. RMS power is the amount of power the speaker can handle at all times.

A higher RMS rating means you can run your system with a larger amplifier. This also means you’ll generally get better sound quality at loud volumes.


Sensitivity is the loudness of a speaker. The higher the sensitivity gets the louder the speaker gets.

Construction Quality

Just like any other product, you want to get the best product possible for the best price. Many of the products on this have high-end materials. From polypropylene cones to titanium tweeters, premium materials will give you better sound quality and the speakers will last for ages.

Style and Design

If you’re not hiding the speakers inside your doors you need to consider the style and design of the speakers. You should choose a speaker setup that matches your style and aesthetic.

Speaker Size

From the best 5.25 car audio speakers to elite level 6×8 speakers, size matters. Whether you’re looking for a balance of affordable performance or the loudest 6×9 inch speakers around, size is an important guide in finding the right speakers for you.


Impedance refers to the amount of resistance the speaker offers to the power that comes its way. Measured in ohms, a higher resistance speaker will need a more powerful amp – and a powerful speaker with a really high resistance will need an aftermarket amplifier altogether.

Impedance is usually 2-, 3-, or 4-ohm. To learn more, check out our in-depth guide to 2-ohm vs 4-ohm speakers.

Component vs Coaxial Speakers

There’s no getting around it – component speakers offer the best sound quality by splitting the woofer and the tweeter. But if you’re looking for something that simplifies installation and is a little more wallet-friendly, then top rated 6.5 inch coaxial speakers offer a good alternative. Because the tweeter, woofer and crossover are combined into a single unit with a coaxial speaker, it’s more manageable for audio newbies.


For many, installation is an intimidating process when it comes to speakers as we don’t all have experience with the electronics and wiring involved.

To simplify the installation, look out for an in-built crossover. With the crossover integrated into the speakers, you don’t need to find additional space in your door for the unit.

Another trick to make installation a breeze is to choose a component speaker with a 3-ohm impedance like the JBL GT0609C 2-way Car Audio Component System. A lower impedance will mean less resistance to the current from an amplifier, so you can get away with keeping the cheaper factory wiring.

Essential Components

Below is what you should expect inside the box when purchasing a 6.5″ component speaker system.

Woofer Speaker

The woofer is the main speaker in any component system. It is responsible for providing deep and rich bass sounds while delivering crystal clear midrange sounds. Most systems use a 6.5” woofer mounted in the doors or on the rear deck in a vehicle.


The tweeter reproduces high-frequency sounds. They are normally 1” in diameter and mounted higher up in a vehicle. If your vehicle doesn’t have OEM tweeters installed, you may need to use hardware to surface or flush mount the tweeters.


The crossover separates your audio signal and delivers the sound to the appropriate speaker. This ensures the speakers play the correct frequencies.

Integrated crossovers directly attach to the speakers and offer little customization. External or active crossovers are a separate component and may let you dial in frequencies to match your vehicle precisely.

How To Mount Your Tweeter In A Component Speaker

Because of the split component setup, the woofer and tweeter will be mounted separately in your vehicle. This is an essential part of the installation process, and you should know what you’re looking for before you buy.

Surface Mounting

Surface-mounted tweeters simply attach to an exterior surface in your vehicle, either on the dash or door panel. This is the simplest way to mount your tweeter, but it can intrude on your vehicle’s decor and has a distinctly DIY feel. To surface mount your tweeter, simply choose your spot and mount the tweeter with a screw.

Flush Mounting

Flush mounting provides a cleaner look – the tweeter will be recessed in your dash or door panel, smoothly integrated into your vehicle. However, the location must have enough depth to accommodate your tweeter, and it requires a more complex installation to drill out the space for the tweeter and run the wiring to your crossover.

Angle Mounting

Angle mounting lets you adjust the angle at which your tweeter sits, offering superior directed sound quality. Usually, angle mounting will be integrated into a flush-mounted tweeter. For truly customizable sound, look out for angle mourning options with your 6.5″ component speaker.

Frequently Asked Questions About 6.5″ Component Speaker

Do You Need an External Amplifier for 6.5″ Component Speaker Systems?

Aftermarket component speakers tend to need more power than OEM speakers. While you can run most of these speakers off your car’s receiver, they normally do not have enough wattage to run component speakers at higher volumes.

This can cause distortion or damage to your new speakers. Investing in an external amplifier that matches the RMS power rating of your speakers will ensure they always have ample power to run effectively.

Do You Need a Subwoofer With a 6.5″ Component Speaker System?

While adding a subwoofer will greatly improve bass response and increase volume levels it is not a necessity for most vehicles. Most of our picks above offer great low-end bass response down to 60 Hz.

Subwoofers let you go even lower and pump frequencies as low as 20 Hz. If you want to feel the bass while driving, you might want to invest in a subwoofer or two for your vehicle.

Unfortunately, adding a subwoofer will also require more amplification and will greatly increase the cost of the speaker system as well.

Wrapping Up…

Many music enthusiasts agree that a car’s sound system isn’t complete without a quality set of component speakers.

Native speakers often lose whatever quality they did have when played at loud volumes. Component speakers can give you the boost you’re looking for without sacrificing sound clarity.

However, every individual is looking for something different from their speakers. Whether you want something you can show off, or something that will last with the bass turned high and the volume higher, there’s a set of 6.5″ component speakers for you.

Just be sure that whatever model you choose has a solid RMS power rating, enough sensitivity to get the party going, a quality build, and the design you’re looking for.

You don’t need to settle for the sound system your car came with. Amp up and feel the music with the best 6.5″ component speakers.
