Buyer’s Guide

Speaker’s power

The power of the speaker can be determined by the power handling rating and the RMS rating. The power handling is how much power a speaker can handle before blowing out. Whereas the RMS rating is how much power the speaker can continuously handle. Both of these ratings go hand in hand and they must be close to each other for the speaker to perform well. If both of these ratings are high, then your speaker will be really loud and still have clear audio. 

Speaker sensitivity

The speaker’s sensitivity also goes hand in hand with the speaker’s power. An average speaker has around 87-88 decibels sensitivity whereas a good speaker has over 90 decibels. The sensitivity determines how loud the speaker will be while using how much power. What this means is that if you are using a low powered amp, getting a high sensitivity speaker will mean that it will use less power but still deliver loud volume. Keeping this factor in mind is really important because it is one of the most significant things when it comes to speakers. 

Size of the vehicle and other speakers in the car’s audio system

The size of your car plays an important role when it comes to the selection of speakers. If you have a big car, you will not only need more speakers, you will need to get louder speakers as well. If that is the case, then going for powerful speakers is the way to go. On the other hand, if your vehicle is small, then you will be fine with smaller speakers that have less power. Keep in mind that larger speakers will also cost more than compared to the small speakers. 

What drivers does the speaker have?

Usually, a speaker will have three main drivers. These drivers include the tweeters, mid-bass and woofers. The tweeters cover the high-range frequency and ensure the clarity of the sound. The mid-bass determines how good the mids will be and it also impacts the bass a little bit. The woofers cover the low-range and the bass. You will have to keep these in mind when getting a new speaker because you will have to choose which genre you usually listen to and pick the speaker that has the required drivers. For example, if you are into music with heavy bass, then we suggest that you get a speaker that has an excellent woofer. 

Why should you consider installing 4-inch car speakers?

First of all, these speakers are a perfect replacement for your stock speakers. They can easily fit into any car without needing to adjust the space. You can simply remove your old speakers and attach these without any hassle. They have better sound quality and better bass than the factory speakers as well. On top of that, these speakers are very budget-friendly and user-friendly. Plus, they are great for entry-level users who are looking to buy their first or second speakers. Once you have heard the quality of the 4-inch speakers, you will not be able to go back to the factory speakers as they will sound really flat. We also recommend that you get a subwoofer and a super tweeter with your speakers so that you can get the full experience. It will ensure that you get thunderous bass and amazing highs. You will be fully immersed in the music that you are listening to. The good thing is that a subwoofer and super tweeter does not cost that much either. Most of the time, there is a deal where these items are available alongside the speaker. Another reason why you might want to install the 4-inch speakers is that they have a stylish design. While your stock speakers might look good, the 4-inch speakers look absolutely stunning. Some even have extra features such as LED lights for added effects. They will look really great in your car and enhance the look of the interior of your car as well.     

Frequently Asked Questions (FAQs)

best floor standing speakers under 500

Which is better 2-way or 3-way speakers?

The 2-way speaker does not have a dedicated woofer built in it. So if you are a bass enthusiast, we recommend that you go for a 3-way speaker. This is because a 3-way speaker has a built-in woofer which enhances the overall bass. 

Coaxial versus component 4-inch car speakers: which is better?

The coaxial speakers are easier to install especially if you are a beginner. They also are cheaper than the component speakers. On the other hand, the component speakers are expensive but they have better sound quality and are more durable. 

Are tweeters a must-have when purchasing 4-inch car speakers?

Well, this depends on your needs. Since the tweeters offer cleaner sounds and better highs, we recommend them to users that love to hear classical music. In fact, any music that does not have heavy-bass will require a good tweeter to sound better. 

Will my new 4-inch speaker fit in factory speaker spaces?

The good thing about getting the 4-inch speakers is that they are lightweight and have a compact design. This means that you can easily fit them in any car without having to make extra room for them. So yes, they will fit in the factory speaker spaces. 

What is the best 4-inch car speaker for bass?

There are many brands that make amazing car speakers that deliver thunderous bass. But the Kicker 41DSC44 Speakers stand out most according to our tests. It not only has amazing sound quality, but it also has some of the best bass that we have ever heard. 

Will my new 4-inch car speakers require an amplifier?

Usually, you will not need an amplifier to power your 4-inch speakers. In some rare cases, you’ll have to get an amplifier. This happens if the speakers that you have installed are more powerful than the stock amplifier. 

Are component speakers worth it?

Component speakers are really good and worth it in our opinion. The only downside to them is that they might be a little difficult to install especially for new users. Other than that, they have a better sound quality than the full-range speakers. 

Will replacing factory speakers make a difference?

We get this question a lot. If you replace your factory speakers, you will hear a noticeable difference. The overall quality of sound and bass will greatly increase. Not only that, the custom speakers have a more dynamic range and in most cases, they also look better.

Is replacing car speakers worth it?

Replacing your car speakers is absolutely worth it. This is because your stock speakers have a limit to how good they can sound. You will notice a major difference once you get rid of your stock speakers and install new custom speakers.  

Will changing car speakers improve the sound?

If you have factory speakers and are looking to install new ones, we recommend that you do so as soon as possible. The stock speakers can only sound so good. If you install the custom speakers, the overall sound quality will increase by a lot.
