Factors to Consider Before Buying the Best 4x6 Speakers

Whether you’re an audiophile or not, you definitely want to enjoy the best sound possible in your car. However, that demands to have the best speakers possible. They come in different brands and sizes. Some are more superior to others. They’re made differently by different manufacturers. Thus, you can’t invest in just any random speaker you come across and expect to get the best sound. There’re certain things you have to look out for to get the best speaker. And what are these factors? Read on to know the factors to consider before buying the best 4 by 6 replacement speaker.

Intended Purpose

Before buying any speaker, you need to know the kind of sound you want. Do you want just mid-range and highs? Or are you after deep bass? Or maybe you want full-range sound? You need to ask yourself such questions before making any investment in speakers. Once you determine the kind of sound frequency you expect from a speaker, then you can go ahead and choose a speaker that is specially designed to deliver that sound frequency.

For instance, if you want more bass, go for a speaker that can deliver deep bass. If you want to hear clear vocals and instrumentals, then go for a speaker that can deliver the best mid-range. If you love full-range sound, then go for a speaker that has multiple drivers and an inbuilt crossover. Also, if you love loud music, go for a speaker that can deliver loud music without distorting. It should be powerful enough to handle higher volume and more power without any problem. Thus, know what you want from a speaker before spending your money to ensure you get the best value of your money.

Also, think about the environment you’ll be using them. For instance, if you live in a highly-humid region, then consider going for speakers whose materials resist moisture. If you reside in a hot area, then you’ll definitely need speakers that resist heat and UV rays, especially if you want to use them in the dash.

Impedance

Another crucial factor to consider is the impedance of the speaker. Impedance is usually measured in ohms. It’s basically the resistance of a speaker to the signals sent by an amplifier or head unit. Ensure the head unit or amp you have in your can be able to drive the speaker. If the speaker cannot resist the kind of power it gets from the amplifier, the amplifier will keep driving more power to the speaker and burn it. Speakers with lower impedance need a more powerful amp to drive them. For instance, a speaker rated as 4 ohms will extract more power from an amp than a speaker rated as 8 ohms. Thus, ensure the speaker you’re buying won’t be overpowered by the existing amp.

Speaker Sensitivity

Another key aspect to consider is the sensitivity of the speaker. Sensitivity is usually measured in decibels (dB). Sensitivity is all about the loudness of a speaker per watt. A speaker that has a low sensitivity rating will demand more power to sound louder. A speaker with a higher sensitivity rating will demand less power to sound louder. Basically, low sensitivity ratings range from 80 to 88 decibels for every watt whereas those rated between 89 to 100 decibels for every watt are considered to have high sensitivity. Thus, if you have a head unit or amplifier that is not that powerful and you need loud sound, then go for a speaker with a lower sensitivity rating. If your head unit or amp is extremely powerful, then you’ll be good with a speaker that has a higher sensitivity rating to get loud sound.

Power Handling

Besides the impedance and sensitivity of a speaker, you also need to consider its power handling. Power handling is all about the amount of power that a speaker can handle without getting damaged. If a speaker receives more power than it’s designed to, then it can distort, crackle, and even get damaged permanently. 

Power handling relates to both RMS power and peak power. RMS power is the power that a speaker can handle continuously without being damaged. On the other hand, peak power is the amount of power that a speaker can handle at one instant. What matters more is the RMS power. Ensure the RMS power of the speaker you buy won’t be overpowered by your existing head unit or amp.

Quality of the Materials

Of all considerations, quality should never be ignored. The quality of the speaker you buy will largely determine the extent of time it’ll serve you. If you want a speaker that will serve you for long, then ensure its components are made of high-quality materials. For instance, ensure the surround, cone, and coil are made of high-quality materials to ensure they don’t tear or burn out easily. Also, ensure the speaker basket or frame are made of high-quality materials to keep the interior components protected.

Speaker Design

Go for a speaker design that matches your preferences and automotive. For instance, ensure the speaker depth is suitable for your car door or dashboard before making a choice. Also, choose between protruding and zero protrusion tweeters in coaxial speakers. If you want to cover the speaker with a grille, then a speaker with zero protrusion tweeters will work better for you. If you want your speaker to remain exposed for aesthetic purposes, then any tweeter design in the speaker will work for you.

Ease of Installation

You’ll definitely want a speaker that’s effortless to install. An easy-to-install speaker is one that matches with your factory speaker holes. If you get a matching speaker, you won’t have to drill new screw holes or new speaker holes. You’ll simply fit it right in and screw it in place. Also, consider a speaker that comes with mounting hardware to make it easier for you to install. If you are thinking to install it yourself you can read our guide on How to Install Car Speakers Yourself.

Consider Your Budget

While the price tag of a speaker should not be the main determining factor when choosing, it still matters. You’ll be surprised to find out that a more affordable speaker performs better than a more expensive one. Always ensure that you buy a quality speaker within your budget to create a balance between quality and price. Also, avoid being overcharged since not all expensive speakers may sound great. Once you’re sure of the kind of speaker you want, look for one that fits your budget.

Personal Preferences

In the end, the ultimate factor to consider when choosing a 4” by 6” stereo speaker is your personal preference. The quality of sound is more of a personal judgment. Every individual have their own taste of what they perceive to be the best sound. One speaker may sound awful to one individual and sound superb to another individual. The best speaker is always the one that appeals best to your ears as an individual. Aesthetics may also matter to some individuals. After all, who doesn’t appreciate good-looking items? Thus, your personal preferences should matter when making a choice.

In conclusion…..

As you can see, there’re many 4 inch by 6 inch speakers available today. If it sounded confusing to make a choice at first, you can now see it’s easier to choose the best speaker with this review and buying guide in mind. After all, this review includes the best of the best speakers, such that you’ll be making your choice from speakers that guarantee high performance.
