How to Choose the Right 4 Inch Car Speaker

Choosing the right speaker won’t be a big deal, if you know what those factors are which makes a speaker great. However, there are plenty of things that build the performance but the factors which majorly affect the quality of sound are power rating and sensitivity rating and of course, the price is also a significant part of your deal.

Let’s see how you need to look into these factors while making the real purchase.

1. Power Rating of Speakers

The power rating is the first indication to know about how powerful the speaker is. The power rating tells you how loud it’s going to produce the sound. While checking the power rating, you should consider the RMS rating as its actual power rating which is mainly responsible for the speaker’s performance.

Because you’re dealing with 4” speakers so make sure you make the best comparison between the power ratings of speakers from top brands. Keep in mind, the more the power rating would be, the higher the sound output would be.

2. Sensitivity Rating of Speakers

Checking the sensitivity rating is one more way of judging the efficiency of a speaker. If the speaker has a high sensitivity rating then despite the low power rating, it will give out great sound. Even the speaker with a lower sensitivity rating can perform well if it has a higher power rating.

The only difference is, with a high sensitivity rating, it consumes less energy to produce the same amount of sound that it produces with a lower sensitivity rating. Hence, the best approach is to consider the sensitivity rating in relation to its power rating, this will help you get the one that claims quality performance.

3. The Size of the Vehicle Determines the Type of Speaker You Need

What kind of speakers you need, it also depends on the size of your vehicle. If you have a small car, you may not need bigger sized speakers and only having a pair of 4” car speakers would be enough to produce a great amount of bass.

But with bigger sized cars, you may need the varied sizes of speakers or you will need to install the most powerful 4” speakers on the door for a high pitched sound.

3. What Drivers Does the Speaker Have?

By looking at the number of drivers, you can determine how well it’s going to perform for a range of sound. Therefore, it’s important to have the speaker that has the right drivers to perfectly work with mids and highs of sound.

In the context of drivers, 2-way speakers are certainly the best upgrade for 4” size of speakers. However, checking the quality of material used for making the twitter is also significant as it determines how clear the overall sound would be.

4. Choose between coaxial and component

Understanding the difference between both will help you choose the one which suits your requirements. Coaxial speakers are full-range speakers that combine all the components in one structure. They have in-built crossover along with a woofer and a tweeter attached to it. Due to their seamless configuration, these are much easier to install, require minimal modification in the car’s interior.

On the other hand, component speakers come with separate drivers that can be installed at different locations according to your sound needs. The disadvantage of this speaker is that the installation is much complicated and time-consuming. You can’t install it on your own despite being great into car audio.

However, component speakers exceed your sound customization options in comparison to coaxial one but it also exceeds your overall budget. So, we highly recommend coaxial speakers that are best in every point of view.

To have unlimited entertainment all the time, we have suggested some of the Best 4 Inch Speakers for car that claim extraordinary efficiency. And to find which one is right for your sound system, we have provided you with a detailed explanation of various factors that are majorly responsible for the best sound output.

But still, if you’re not sure which one to choose then simply go with our top pick rather than taking random recommendations. Our top pick is Polk Audio DB401 4-Inch Pair Coaxial Speakers that are certainly the best simple upgrade for the vast majority of people.
