Guide for Choosing the Best 4 Inch Car Speakers
Once you know what your car stereo needs to perform better, purchasing the right speakers isn’t a complicated process. The main factors to consider are the amount of power that a speaker provides, its sensitivity, how it fits in the car’s sound system and whether it meets your listening tastes. Your budget definitely comes into play when purchasing any type of speaker.
Firstly, the speaker’s power will determine how loud it will produce sound. As with all speakers, the RMS rating is the most accurate measure of the speaker’s sound performance.
While checking this rating is quite simple for the majority of users, it’s easy to be confused by peak power/MAX rating that often overestimates the speaker’s power. Be keen to compare 4-inch speakers using RMS rating to ensure you get the best. And as usual, a higher RMS rating means more sound output all other factors held constant.
Sensitivity is measured in decibels (dB) and shows the speaker’s efficiency in using the available power. To get the best idea of a speaker’s sound output, consider its sensitivity in relation to its power handling and that of the entire system.
A speaker with a high sensitivity rating can work well with a low-powered system. So even though such a speaker may have a lower power handling capacity, its high sensitivity makes sure that it produces more sound with less energy.
On the other hand, if your car has a high-powered system, a speaker with a high power handling capacity will work just fine even if it has lower sensitivity.
Size of the vehicle and other speakers in the car’s audio system
Different cars need varying numbers of speakers of different sizes to deliver the best sound. Bigger cars obviously need more speakers. If you have a big car that has bigger-sized speakers like 6 X 8s, 6 X 9s or subs, you will most definitely need to install powerful 4” speakers on the doors for fuller sound output.
Small cars may not have many different-sized speakers and subs because of space constraints. Therefore, installing a pair of high-quality 4” coaxial speakers with a good amount of bass may be enough for a better listening experience.
What drivers does the speaker have?
Most 4-inch speakers are best suited for mids and highs. It is therefore important to make sure the speaker you choose has the right drivers for this purpose. The quality of the tweeter is especially crucial as it determines the clarity and overall quality of sound.
Everyone has unique needs but here are some general recommendations for 4” speakers:
- If you are just looking for a sound upgrade, we recommend coaxial 4” speakers. But if you are doing an overhaul to your car audio system, components may be the better choice
- If you are into rock and other music genres that don’t have booming bass, don’t shy away from extending the high range of your stereo by installing 4” speakers with tweeters and super tweeters
- Don’t spend too much money on speakers with super tweeters if you aren’t planning to replace the entire audio system.
Frequently Asked Questions
Q. Why should you consider installing 4-inch car speakers?
A: 4-inch car speakers are the right choice in two scenarios. First, an aftermarket 4-inch speaker makes a great replacement for stock speakers if you want to end up with more balanced audio. Also, many users consider them as inexpensive and worthwhile upgrades to factory speakers. It is for this reason that four-inch speakers are fairly common in many vehicles.
The second scenario is when you are making a complete upgrade of your entire car audio system. You have already installed some good subs and now want to extend the high frequencies. 4-inch speakers with tweeters and super tweeters will enable your system to deliver higher-end frequencies more efficiently.
Q. Coaxial versus component 4-inch car speakers: which is better?
A: The decision of whether to go for component or coaxial 4-inch car speakers rests on many factors including your installation skills/budget. Coaxial speakers are relatively easier to install compared to component speakers. You can quickly set up coaxial speakers with minimal technical skills.
The installation process for component 4-inch speakers is a little trickier. Each of the drivers needs to be controlled separately, so it will take more time and effort to wire a component speaker. That said, however, you could be planning to overhaul your system for better sound performance. In this case, it is better to go with component speakers. Components give you a richer acoustic experience than coaxials. Therefore, they are a longer-term solution for better sound quality.
Q. Are tweeters a must-have when purchasing 4-inch car speakers?
A: Tweeters enable the audio system to give better highs and cleaner overall sound. If you love listening to music genres that don’t have heavy bass, you know that high-frequency drivers are critical elements of the audio system. Consider installing 4-inch speakers that have tweeters and super tweeters.
You should not worry about looking for speakers with tweeters and super tweeters if you just want a simple upgrade for stock speakers. There are many good, inexpensive 4-inch speakers without tweeters that will bring significant improvement to the sound your system delivers.
Q. Will my new 4-inch speaker fit in factory speaker spaces?
A: For many vehicle models, it is possible to interchange 4-inch speakers without any space challenges. There are high chances that the frame of your new speakers will fit exactly where stock speakers were screwed. But it doesn’t hurt to measure the dimensions of the space left by factory speakers before you go out shopping for new speakers. And if you intend to fix the new 4-inch speakers on the car’s doors, make sure there is enough space for the speaker. Most 4-inch car speakers have an installation depth of about 3 inches. Ensure that the door has sufficient space so that the newly installed speaker will not be in the way of the car window.
Q. What is the best 4-inch car speaker for bass?
A: Generally, well-selected 3-way 4-inch speakers will reproduce low frequencies better compared to most 2-way speakers. In a 3-way system, the woofer is specifically dedicated to low-frequency signals while mid-range drivers take care of the rest of the frequencies. As a result, the 3-way system delivers deeper, more pronounced bass.
It is important to remember that a car speaker with more drivers doesn’t automatically become the better-sounding speaker. Each car is different, and it’s not unusual to find a 3-way speaker sounding better than a 4-way speaker in a particular type of car. Thus, the best 4-inch speaker for your car is the one that fits perfectly in your car and fulfills your listening needs.
Q. Will my new 4-inch car speakers require an amplifier?
A: No, if you have a head unit that can power the speaker, and yes, if the stereo’s or head unit’s power handling falls short of the speakers’ power requirement. Powerful head units like Pioneer AVH-W4500NEX and Sony XAV-AX100 are among the most versatile head units on the market. Many speakers with power ratings ranging from 50 watts to about 220 watts will do well with these head units without requiring a standalone amplifier. The power handling capacity of the speakers you choose will determine whether or not you need to install an amplifier.
