Best 6.5 Inch Car Speakers of 2018 & Buying Guide

Highway hi-fi comes plain or fancy. It all depends on the speakers of your car. In most cases, factory-installed car speakers are not perfectly made to meet all your requirements. So, it makes sense to upgrade your auto sound equipment for maximum enjoyment.

Upgrading your car sound units does not need to be an expensive and complicated proposition. A few dollars well spent will improve your musical return many times. The inexpensive and reliable upgrade simply involves replacing your car speakers with better models.

New construction techniques, technologies, and materials make upgrades in 6.5 inch speaker size more feasible. The only challenge that you might encounter is deciding on the best model to buy. The best 6.5 inch car speakers reviews provide useful and reliable buying information.

Things to Consider Before Buying

Speaker style

The first consideration that you have to make when shopping for 6.5 inch car speakers is the style. There are two major styles to choose from; the coaxial speakers and the component speakers.

Coaxial speakers

Coaxial speakers are usually made of two or more frequency drivers mounted inside one speaker surround, but driven by a single voice coil. The different cone sizes are mounted on top of each other and terminating at a central point.

A two-way coaxial speaker has two components; the low-frequency driver (woofer) and the high-frequency driver (tweeter). The combination of the two drivers generates a full range of sound frequencies within a car, all radiate from a central position.



Coaxial speakers are very effective in reproducing a spectrum of frequencies, but they offer limited room for improvements in audio performance because of the design. However, they are the most preferred aftermarket speaker replacement.

These speakers are engineered in common sizes, such as 6.5 inch speakers. This makes upgrades remarkably easy since there is no need of cutting new holes in body panels to fit component speakers.

Component speakers



On the other hand, component speakers are matched with separate drivers to reproduce the desired sound frequencies. The entire system is made up of woofers (low-frequency drivers), tweeters (high-frequency drivers), crossovers (small boxes that divert low frequencies to woofers and high frequencies to tweeters).

The next important part of the component speakers is the mounting hardware. The mounting hardware is necessary for adapting crossovers and tweeters to different car interiors. Basically, component speakers are made up of drivers that are physically separated.

There are several benefits of using component speakers. You can install them in your car cabin for maximum performance. They are also known to reproduce a more effervescent and accurate sound for greater realism.

The performance benefits of component speakers certainly outweigh those of coaxial speakers. However, they are not user-friendly for upgrades, not to mention that their installation is complex and there are many considerations to be made.

Performance of the speakers

Choosing the style of the speakers is the first step, but the real challenge is with the performance features. You cannot just go into an electronic store and pick aftermarket 6.5 inch speakers for your car. You have to be sure of what the speakers can do for you.


One of the most important performance features that determine the efficiency of the best 6.5 inch car speakers is sensitivity. This particular specification tells you how much power a speaker requires to attain a specific volume level. It also indicates the possible maximum loudness of the speaker when supplied with a given amount of power.

6.5 inch speakers with a high-efficiency rating require less power to deliver loud sounds; whereas, those with lower sensitivity require more power to deliver loud music. Therefore, you have to settle for speakers with the appropriate sensitivity level. A high-powered car stereo system requires low sensitivity speakers and vice versa.



Power handling



Car speakers come with two power handling ratings; peak and RMS power. The peak power refers to the maximum power a speaker unit can handle in a short musical surge. The RMS power refers to the expanse of power a speaker can handle continuously.

As far as power handling capability is concerned, you should be mainly concerned with the RMS power. For instance, if you have speakers with an RMS rating of 125 watts per pair, then this means that the units are capable of handling 125 watts without any damages.

To achieve the best possible performance, the speakers you select need to be sufficiently powered. However, you do not want to overpower your speakers since you can easily destroy them. With that in mind, the RMS ratings of the speakers you settle for must be close to the output of your car stereo system or amp.

Speaker channels and construction

As you will learn from the best 6.5 inch car speakers reviews, the most preferred 6.5 inch units are either 2-way or 3-way designs. A 2-way speaker splits the work of a full-range speaker in two; a tweeter to reproduce high frequencies and a woofer to reproduce low frequencies. In the same way, a 3-way speaker divides the work among a midrange driver, a tweeter, and a woofer.

In addition to the 2-way and 3-way constructions, there is a wide variety of specialized designs you can choose. Many models consist of adjustable tweeters that focus at your listening position. This kind of setup will improve coverage throughout your car and enhances stereo imaging.



Value for money and guarantee

You should settle for the desired price range once you know the features to look for in 6.5 inch speakers. Most high-end designs are usually pricey. However, this does not mean that you cannot get inexpensive speakers that are high performing.

When you browse the internet or walk into an electronics shop, you will come across different brands of 6.5 inch speakers. What you should look for apart from the price are the designs and performance features. You will definitely come across models that best suit your budget and sound requirements.

The warranty of the car speakers you buy is also important. Make sure you buy your 6.5 inch car speakers from a well-known brand with long-standing exchange policies and return.
