Buyers say these speakers sound great in both directions and offer excellent midrange and triple tone but little bass presence due to the 4-inch size. They perform well for their size but are increasingly saturated. Therefore, you will need to lower the sound balance between these speakers and the rest of your car to keep the volume down and avoid distortion. To stop.

So if you see something with bass, you’ll have to look elsewhere. These sounds are best matched with a crossover network to minimize and avoid distortion. I push 100 watts for these little people, and they feel great!

10. Kicker KSC404 KSC40 4

Product Information:

Kicker KSC404 KSC40 4

  • Mounting Depth: 1.75″
  • Power handling:
  • RMS: 75W
  • Peak: 150W
  • Frequency response:  60-20,000 Hz
  • Impedance: 4-Ohm
  • Speaker Size: 4 Inches

The kicker is one of the best 4-inch full-range loudspeakers on the market. The device has two silk tweeters and firm rubber edges. Each tweeter has a maximum power consumption of 150W, but for optimal performance, we recommend using it with a continuous power consumption of 75W.

This kicker model’s frequency response is between 60 Hz and 20 kHz, which leads to perfect highs and lows. This speaker has a sensitivity of 88 dB, which results in excellent sound clarity with this device. Despite being a typical 2-way car radio speaker, the bass on this instrument is perfect.

This device’s woofer cone is made of polypropylene; the device is 11.4 x 5.9 x 3.2 inches and weighs approximately 2.43 pounds. One of the great things about this speaker is its short stature. Therefore, they can be easily mounted on any car.

The stable build quality of this speaker adds to its sound quality. The silk domes used in this device make the sound very soft on your ears. It also has an expanded dynamic range. This system’s sound is very sharp, and the even pitch you get from this device is almost inevitable.

Recent Buyer Reviews On Kicker KSC404 KSC40 4

They are excellent for what they are. Some buyers bought these for a custom project, and they looked amazing for kickers. Thought it would be all bass like standard kickers, but it’s a decent amount of medium and treble. We want the speaker grills to be more low profiles, to run for the project without them because they interfered with the car interior.

The overall buyers recommended it to everyone.

Types of speakers

There are two types of speakers to choose between full-range and component.

Full range speaker

As the name suggests, these speakers have all the necessary components to reproduce the full range of frequencies, from low to high. The simpler ones have a woofer to handle bass and a tweeter to handle higher frequencies. More complex models may also include a midrange driver (for frequencies between 200Hz and 2000Hz, which determines how “sound” is present) or super tweeter (for ultra-high frequencies).

Component speaker

Compared to full-range speakers, component speakers have one additional component: an external crossover.

Crossovers are filtered, directing frequencies within a specific range to the correct driver: low frequencies to the woofer, mids to the mid-range driver, and high frequencies to the tweeter. This puts additional pressure on these drivers, who would otherwise have to work harder to reproduce frequencies outside their handling range.

Last but not least, component speakers are often made of better material than full-range speakers. This means that they last longer and emit higher quality sound. How does the material affect quality and durability? That’s precisely what I’m going to address in the next part.


The component

In this section, I will talk about the primary materials present in the speakers of a 4-inch car and how they affect the accuracy of sound reproduction and the life span of the device.


Most woofer cones are made of synthetic materials such as polypropylene, which makes them stiff but lightweight at the same time. Rigidity is necessary because it helps the speaker reduce sound at high volumes, thus preventing any unwanted distortion from occurring. Some woofer cones are also made of stiffer by mixing polypropylene with a mica-like material.


Typically tweeters are made of soft materials such as silk or textile blends or hard materials such as metal or ceramic. The former allows the tweeter to emit a very sophisticated, smooth, and warm sound. However, soft tweeters are not durable and lose high volumes of precision due to poor sound damping. That being said, you can buy silk tweeters that have been mixed with synthetic films, which are stiffer and therefore, can handle higher volumes.


The surround sound is the ring that surrounds the woofer cone and connects it to the speaker basket. There are two things to expect from the right environment:

It should be sufficiently flexible to allow the woofer to vibrate freely, allowing the bass to be heard without interruption.

It should be strong enough to prevent the woofer from going too far.

Materials that meet this requirement include rubber, foam, and clothing. Of these, rubber provides the best durability and precision. Perhaps that is why most of the environment around me is made of rubber.

Factors To Consider Before Buying A 4 Inch Car Speakers With Good Bass

We want to talk a little bit about what you want to see in a 4-inch speaker. This includes the speaker’s technical aspects such as its sensitivity and power handling, the material from which it is made, and whether it is a component speaker or a full-range speaker. If all this sounds confusing to you, don’t worry. I am going to break down each of the factors so that you understand why they are essential.

Quality Construction

The build quality of a speaker should also be considered, as it may affect the audio system’s sound quality. What to see here are tweeters, woofers, and speakers all around. The materials used here, the amount of heat around the system, and the speaker’s weight all contribute to the sound quality.

Speaker size

The car speaker’s size depends on your choice because the size is usually between 3.5 inches and around 9 inches. The sound quality also varies depending on the size of the speaker. For example, larger ones offer a better sound, while smaller ones have adequate sound bandwidth. However, when choosing a specific size for car speakers, consider how and where you want to place them. If you are looking to buy larger speakers, you may need to change the mounting structures and settings to fit your car.

Sound Quality

The most important thing when purchasing a speaker for your car is the sound quality. You have to look at the frequency range of a speaker to determine your speaker’s sound quality. The wider the frequency ranges of a particular speaker, the better its sound quality.


Sensitivity measurement (in decibels) of a speaker when it is supplied with one watt of power, For example, if a speaker’s sensitivity is 85 dB, it means that the speaker will emit a moderate amount of sound when powered by one watt.

It is better to combine high-power car audio systems with higher sensitivity (greater than 90 dB). This is because the former cannot generate too much electricity, and the latter does not need to reach high volumes. As a result, you will not put too much weight on the audio system and not risk damaging it.


Power handling is also an important aspect. Knowing RMS and peak power input can handle your speaker. It is essential to understand that power management’s critical factor is maximum RMS and not maximum power input as people may think. For example, a high power stereo requires a “10-80W RMS” speaker and not a “Monster W RMS”.

2 or 3-way speaker

Another thing to consider is whether the speaker is a 2- or 3-speaker. Most car speakers come in these two variants. 2-way speakers are common units, also known as coaxial speakers. They bring a tweeter and a woofer.

The only thing that differs from 3-way speakers is the 2-way; they come with an additional mid-range component. This gives 3-way speakers a higher frequency range, resulting in better sound quality.


Speakers can cost a lot if you don’t know the general market price. Before buying a car speaker, browse the different speaker price ranges and what features are available with them. If you plan to add a new and unique sound system to your car, the price may be out of budget. If you’re looking for replacement speakers, they are inexpensive and easy to install.

Frequently Asked Quesions

How car speakers work

A car speaker contains a stack of elements and concepts that improve the workings and produce better sound. The production work process can be controlled by combining certain factors and how to respond to the problem at hand. The process begins when an amplifier generates electrical pulses that give negative voltages a flattering shape. This creates an electromagnet after reaching the voice coil in the speaker. By moving forwards and backward, different degrees of air pressure is generated. These movements would later change in frequencies, resulting in “sound”. All of this can be managed using the settings and buttons present in the system. Each setting and option helps you control volume, change channels, and many other things.

How to install a car speaker properly?

Car speaker installation isn’t as difficult as it may seem to beginners. With the right tools and guidelines, almost anyone can! Before you begin, make sure you design a toolbox filled with all necessary accessories such as screw drawers, drills, hex keys, mounting hardware, wire cutters, etc.

Don’t forget to read the operating instructions thoroughly!

Follow some easy steps

  • Move and disconnect your vehicle’s battery before installation to avoid power loss. This will also ensure that you will not receive an electric shock during the installation.
  • Now use the means of the right to separate the vehicle door that you want to set your new car’s speaker on.
  • You can find the standard speaker in the door. Carefully cut it off, then remove it.
  • After removing the standard speaker, disconnect the factory wiring harness. Now is the time to install a new wiring harness for your new speaker. Later, plug the back end of the wiring harness into the vehicle’s wiring harness.
  • Test the speaker to see if it works properly. If it doesn’t, recheck the connection.
  • You are almost done! All you have to do is reassemble the door and have your new car speaker ready to use.


Most standard car speakers are 4 inches in diameter. When you buy a speaker in this size range, you can change the factory settings without any modification.

Finding the best 4-inch speakers for car among large options could be confusing. But the above reviews were structured to shorten your big list. You have now a shortlist and you can choose a perfect car speaker from the list. Our editors best recommendation is – Rockford Fosgate P142 Punch 4″
