Best 6.5 Inch Car Speakers for Bass

Let’s set the scene.

You’re driving in your car: maybe you’re on a road trip with your closest friends, or maybe you’re heading home after a stressful day at the office. Your favorite feel-good song comes on, and all you want to do is feel the cathartic release that comes with singing terribly at the top of your lungs as you coast along the highway, waiting for the beat to drop.

You crank the volume up as it gets closer, and right at the moment before it drops… the sound quality peaks, causing the music to crackle and distort. Is there anything more disappointing? 

Although your car sound system is probably fine for short journeys and quieter use, once you reach a certain level of volume, the music has a tinny, distorted quality that can ruin even the best songs.

Whether you’re belting out Beyonce, singing along with Celine Dion, or rapping to Kendrick Lamar, a pair of 6.5-inch car speakers is going to vastly improve your sound.

They’re an excellent choice for anyone looking to upgrade their factory speakers, and they’re available at an extremely affordable price.

Best 6.5 Car Speakers for Bass Buying Guide

Volume frequency and power output

If you like to blast your music as you drive then you’ll probably be paying close attention to the frequency range of your speakers, as this is what determines how exceptional the sound quality is. 

RMS stands for Root Mean Square whereas PPO refers to the Peak Power Output.

Confusingly, some brands only advertise the PPO in their product specifications, but it’s the RMS rating that indicates the volume of the speakers as well as the amount of constant power the speakers can sustain without any impairment to the sound quality.

High output tweeter car speakers tend to have in-built cooling methods in order to reduce the risk of overheating, as this can affect the sound quality and shorten the lifespan of your speakers.

(All about that) Bass

In order to produce a really great bass quality, you’ll need speakers with both a subwoofer and an amplifier, as these are the two main components that affect the bass.

Subwoofers are designed to help produce low-frequency sounds in heavy-bass music, especially when it comes to car speakers as their small design struggles to produce lower frequencies alone. 

An amplifier is essential for any car speaker as it increases the power of the signal. Either built-in to your speakers or installed separately, the amplifier is what converts the low-voltage signals into more amplified sound. 

Coaxial speakers vs. component speakers

The difference between a coaxial speaker and a component speaker is that a coaxial speaker incorporates the woofer, tweeter, and crossover in a single speaker, whereas the component speakers feature these three components individually. 

Component speakers work best at delivering both ultra-high and ultra-low frequencies, but coaxial speakers have a more complicated system. Their built-in subwoofer is essential as it enables low-mid range frequencies, allowing the speaker to focus on high-frequencies alone. 

Although coaxial speakers are more compact, they still deliver powerful, high-quality sound without taking up so much space in your car. 

Any audio-enthusiast would agree that when it comes to audio quality, component speakers are much more reliable at producing premium sound. However, they can be difficult to install due to the individual components as these require separate mounting, and the improved quality comes with a higher price tag. 

Shape and Size

Due to the limited space in which they inhibit, car speakers are designed to be smaller than your average speaker, with the average size being 6-6.5 inches.

Most speaker models come in regular size as well as a shallow version which is an extra compact design. They are typically circular in shape but can also be oval with a size of 6 x 9 inches. 

When choosing your speaker size, it’s important to think about the intended location for your speakers and its available mounting depth. If your speakers do not fit they may need to be modified, in which case it’s worth hiring a professional to install them in your car. 


Most 6.5 inch speakers will be less expensive than a larger 6.9 speaker, although this may vary depending on the brand and model. Component speakers are more expensive compared to coaxial speakers, but they also outperform them in a number of ways so the extra cost is accounted for. 

It’s also worth taking the durability of the speaker into account when deciding which model to purchase, as this will influence how long you have before you’ll need to replace them.

For example, lower-end car speakers have a cone made of paper which is a material prone to damage and will require replacing sooner than a set of car speakers that were built to last.  

You get what you pay for when it comes to car speakers, so if you’re looking for that extra high-quality sound for your music then expect to pay a higher price. 

Frequently Asked Questions

How many speakers should I put in my car?

Most speakers come in a pair and can be installed as two speakers, but to get more of a surround sound effect you can install 4 speakers in your car. 

Is a dome tweeter or a cone tweeter better?

Typically a dome tweeter is the better option as it will ensure better dispersion than you’d get using a cone tweeter.

However, it’s worth researching the different material options as this will alter the quality of the sound. 

What’s the most important factor to consider for good bass?

The amplifier and the RMS rating both contribute to the quality of the bass, as the amplifier boosts the speaker’s sound while the RMS rating indicates the level of power your speakers can handle so you’ll want to look out for a higher rating.
