Buying Guide for the Best 4 Inch Car Speakers

When buying a 4-inch car speaker set (or any other size speaker), you need to consider several factors, including the type of speakers you plan to install and the unique features and characteristics of different models that fit your budget.

If you are not sure what to look for, finding the right speakers may be a bit of a hassle. To help you, here is a brief introduction to some things you should pay attention to. 

Build Quality:

Be careful when buying cheap speakers. In the low-end market, you can’t expect the same stringent standards as high-end speaker systems. Therefore, it is worth spending time researching reviews and understanding what others think about the quality of the speakers you will buy before spending money. Of course, you should always prefer the good build product which ultimately gives you quality.

Speaker Types: 

There are two main types of speakers to consider when choosing the best 4 inch speakers for car: 

Coaxial (Full Range): The full-range speaker consists of a cone and a tweeter in a single device. People looking to replace factory-installed speakers are usually the most popular type of speaker because they are cheaper and easier to install. 

Component Speakers: On the other hand, component speakers are much more expensive and more complicated. A typical component system includes separate external woofers, tweeters, and crossovers that work together to provide the best sound. 

Power Handling:

Power is measured in watts (RMS) and represents the power of a speaker before the sound quality drops. If you want to use a high-power amplifier, you need to make sure your speakers can handle it. Otherwise, your music will sound bad and may explode or damage the speakers and electric system of your favorite car.

Higher Sensitivity: 

Sensitivity refers to the energy required by the speaker to produce sound. If your speakers have higher sensitivity, they will use less power. Therefore, they may be more suitable for low-power stereo speakers, such as low-cost aftermarket or factory-installed models. Conversely, speakers with low sensitivity require more power.

Surround Materials:

Speaker encircles the woofer cone with the ring and connects it to the speaker basket. Two things can be expected for good surround sound. First, it must be flexible enough so that the subwoofer can vibrate freely, and the bass can be transmitted unhindered.

Second, the subwoofer won’t go too far. Materials that meet this requirement include rubber, foam, and fabric. Among them, the rubber seems to provide the best durability and accuracy. This is why most car speakers are made of rubber.

Size in Vehicle:

Cars of different sizes require different numbers of speakers of different sizes to provide the best sound. Obviously, bigger cars need more speakers and larger speakers, such as 6 x 8, 6 x 9, or a subwoofer.

To get a fuller sound, you definitely need to install powerful 4-inch speakers on the car door. Due to lack of space, small cars may not have many speakers and subwoofers box of different sizes. A pair of high-quality 4-inch coaxial speakers with plenty of basses may be enough for a better listening experience.

Fixing Materials: 

You must consider whether the speakers are provided with fixing materials, such as mounting screws, adapter rings, and speaker cables. The speaker with mounting accessories makes installation easy and hassle-free.

For example, if the new car speaker comes with a mounting adapter plate or ring, it can be more easily installed in most speaker holes without cutting new speaker holes instead of buying them separately.

Drivers Requirement:

The number of drivers in a car speaker gives you an idea of ​​how they perform across the entire audio spectrum. The 2-way speakers use tweeters instead of woofers, and 4-inch speakers are best for midrange and high frequencies. So subwoofers are a way to ensure that they can also play low frequencies. 

Super Tweeter: 

When you build the entire audio system for your beloved car, the tweeter and super tweeters will stand out first. As a result, you will notice higher frequencies and more precise sounds.

However, to upgrade the entire system, consider replacing 4-inch speakers with tweeters. The results can be disappointing without the tweeters, so please consider carefully before taking this step.
