Best Car Speakers for Bass and Sound Quality

If you are looking for new car speakers, you most probably want them to be nice and to reproduce quality sound. However, not all speakers on the market are good and you should be careful when choosing if you do not want to be disappointed after their installation. To make the right choice, we strongly recommend reading this article, where you will learn about the technical parameters, types of speakers, and the methodology for choosing the best car speakers for bass and sound quality.

Car Sound Systems

When choosing the best car speakers, one of the first things you will encounter is whether to take a component system or coaxial speakers. Both types have their advantages and disadvantages. However, let’s mention that for people with a limited budget, coaxial speakers are the better choice, and they are quicker and easier to install.

Component systems

As you can probably guess from the name, these car sound systems are made up of several separate components, including bass, midbass, midrange, and treble. The set also includes filters to which all the speakers are connected and they separate the reproduced frequencies. Thus, thanks to the filters, the bass will reproduce only the low frequencies, the mids only the mid-tones, and the tweeters only the treble. This is what will provide you with the best car audio setup for sound quality.

Car component systems offer much better and clearer sound thanks to the individual parts and the fine-tuning that comes from the filters. Accordingly, if you are looking for the best car speakers for bass and sound quality, choosing such a system is recommended, especially if you want to pamper yourself and your companions.

But component systems are significantly more expensive than coaxial speakers, which may not appeal to people who have a certain budget. They are also more difficult to install due to most of the individual components. If you do not know in the field, you will probably have to seek professional help, which will cost you extra.

Coaxial speakers

These speakers have several parts of a system in one chassis (usually midbass and treble), respectively, they reproduce bass, midrange, and treble. Coaxial speakers are common in older cars. They are the preferred choice of consumers when looking for sound improvement without the need for a large investment. For most drivers, coaxial speakers are an affordable option that can offer quality sound if chosen more carefully.

If you plan to install your new car speakers yourself, then it is better to choose the coaxial ones. The disadvantages of coaxial speakers are that there is no possibility for their precise adjustment and their sound is not as high as in component systems.

Types of Car Speakers


These are more massive in size and weight speakers that reproduce the lowest and bass frequencies. Their diameters range from 6.5 and 8 inches to 12 and 15 inches. If you want the sound in your car to cover the entire frequency response and to have the best car speakers for bass and sound quality – then the installation of a subwoofer is recommended.


These are speakers that reproduce low and mid frequencies. They are relatively light and are usually made of polypropylene.

Midrange speakers

These speakers are most often relatively small and light. Their diameter can vary from 3.5 to 6.5 inches. They are optimized to reproduce midrange frequencies, usually from 500 Hz to 4 kilohertz. Most musical instruments and vocals fall into this frequency range. That’s why midrange speakers are a must for the best car audio setup for sound quality.


These speakers reproduce the highest frequencies that mids and midbass cannot reach. Thanks to them you will hear a much more detailed sound from vocals and instruments. The tweeters are the smallest and not as powerful as the others, but their purpose is only to complement and complete the sound picture.

What to Consider to Choose the Best Car Speakers


If you prefer to listen to a certain style of music, then you can adjust the speakers accordingly. For example, if you prefer hip-hop, you can choose something with higher bass. Fans of rock music would like a clearer sound with good detail in the mid and high frequencies.

If you do not listen to a specific style of music, then you can easily get a balanced speaker or component system. For some drivers, the bass sound is too much and some even find it distracting. If you are not a real fan of bass and low frequencies, you better look for car speakers that can reproduce the quality and well-balanced sound.


Each speaker can carry a certain amount of power, which is supplied by the amplifier or directly from the car’s music player. There is a rated power that is real, as well as a peak that is maximum and a speaker can only handle it for a short time. To choose the best car speakers for bass and sound quality, it is important to consider their power – this way you will avoid problems and damage.

The more important power indicator is the real one, which is referred to as RMS. It is one that the speaker can endure even for a long time. Logically, if you supply a speaker with more power than the maximum it can handle, it will be damaged. Therefore, when choosing speakers, it is important to know what power they can withstand and to assess whether they fit well with the power of the amplifier or car player.


Speaker sensitivity is also an important factor not to be overlooked. It is measured in decibels. The best car speakers have a high sensitivity, for example over 90 decibels. This is especially true if you have a weak amplifier or will be using a car player.

Speaker dimensions

Before focusing on specific speakers or a component system, you should check the size of the factory speakers in the car. Accordingly, the new ones must have the same dimensions if you want them to fit in the car. Car speakers are available in different sizes, but the most common is a diameter of 6.5 inches. For the dashboard, the most common size is a 4×5 inch ellipse, and for the rear doors 5.25 inches.

Strength and durability

Although the speakers are installed in the car, they are still exposed to high and low temperatures, humidity, and other weather conditions. Accordingly, the materials from which the speakers are made are important for how long they will last and how good they will sound even over time.

Midrange speakers and midbass are most important for the sound picture, as they cover the widest frequency range. The best car speakers for bass and sound quality from this type are made of rubber. It withstands extreme temperatures and high humidity. However, other materials such as fabric and foam are used in the manufacture of subwoofers – these speakers are usually cheaper and relatively strong.

Subwoofers should be made of strong but relatively light material. They usually have a metal or aluminum chassis, and the speaker itself is made of polypropylene. These speakers are made to behave equally well in cold, heat, and humidity.

Speaker dimensions


Car speakers vary in price in a very large range – you can find them for tens, hundreds, or even thousands of dollars. Therefore, it is best to set a budget and stick to it. At the end of our guide for the best car speakers for bass and sound quality we will give you suggestions for every budget, so you have nothing to worry about.

Best Car Speakers for Bass and Sound Quality

Here we will present you with some of the best car speakers and component systems. Just choose the one that best suits your budget and requirements, but remember to make sure the size fits.

Hertz HCX 165

Among the speakers we chose for the ranking of the best car speakers for bass and sound quality, Hertz stands out significantly. Coaxial speakers are most often used in simple installations without high-quality requirements. In terms of sound, however, Hertz is definitely among the best. The 20 mm high-frequency directional diffuser is located directly in the center of the mid-range and provides an even sound pattern.

Besides, the speakers have one feature that is not reflected in the description. They must be installed in the door in a strictly defined position. The guides of the cap must be oriented vertically. In this case, the frequency response becomes smoother, and the different direction of the speakers becomes minimal. This is the main problem with coaxial speakers. With Hertz, this was avoided.

If coaxial acoustics can sound good, then it is called HCX 165. Besides, Hertz is easy and inexpensive to install. When working with an amplifier, the volume of the speaker is manifested, and the low frequencies open even deeper.

  • Minimum unevenness of the coaxial acoustics of the channel
  • Excellent clarity at high volume
  • Quite an affordable price
  • Excellent materials
  • Stable diffuser
  • Requiring installation orientation
  • Excessive emphasis on the high range

Polk Audio DB6501

More expensive does not always mean better. Polk Audio speakers prove it completely. They have good sensitivity and have a clear block at frequencies below 100 Hz. Moreover, the double tubes with different diameters of the diffusers give a top noticeable result in terms of sound not only for the passengers who are close to them.

Another advantage is that here the frequency response is also far from linear. There are two serious curves in the range of 2-3 kHz and 7-10 kHz, the first being the most audible for the driver. This means that the sound is re-accented and you may need to adjust the equalizer to your liking. Regardless of the settings, however, you will always get a deep, clear, and strong bass. Sure, this kit is budget acoustics, but it has an incredible value for money.

The material of the diffuser is the most traditional and reliable – polypropylene, and the holder is relatively strong. The protective frame is made of plastic together with 8-beam protection of the diffuser – such constructions are becoming more and more widely used. The diameter of the soft membrane is 27 mm.

  • Well designed 
  • Great value for money
  • Excellent way of work
  • There is no sound mixing even at maximum volume
  • Universal mounting locations
  • Slight distortion at the bottom of the register (1.49%)
  • Shallow low-frequency level

Alpine R-Series 6.5 Inch

Alpine R-Series 6.5 Inch

If you like listening to loud music, the R Series speakers are for you. These speakers reproduce a loud and at the same time clear sound without interference. They are suitable for combination with R-series subwoofers and amplifiers. Their maximum power is 300 W and RMS power – 100 W. The frequency range is also more than good – 65 Hz – 40 kHz.

Alpine is one of the oldest and most established manufacturers in the industry. The new generation of the R-Series speakers they offer is better than the same first-generation speakers. The size of the sound coil is larger – 35 mm, the diameter of the neodymium magnet is larger. As a result, the speakers reproduce more powerful bass and deservedly find their place among the best car speakers.

When we want high-quality columns, their material is more than important. Alpine uses CFRP (Carbon Fiber Reinforced Polymer) to make its speakers. It is a very light but strong material. In the most common membranes, the boundary zone is weaker than the central one. As CFRP material is malleable, it can be processed in the molding process to reinforce weaker areas. In this way, the same strength is achieved for the entire membrane and sound reproduction is better and more efficient.

  • An aluminum coil that provides clearer sound, especially at mid frequencies
  • Adapters for easy installation in all cars
  • Neodymium magnet
  • Rotating tweeter 
  • R series is specially designed to reproduce loud sound
  • High price
  • Not enough crossover settings

Polk DB652 UltraMarine

Polk speakers produce very high-quality sound. As they are slightly more affordable than some other speakers and offer several valuable extras, they are also best suited for buyers who prioritize value and want a lot for their money.

The speakers have a diameter of 6.5 inches or 16.5 centimeters. They have a real power of 100 watts and a maximum of 300 watts. They work at 4 ohms. Their sensitivity is 92 decibels. Polk reproduces frequencies from 68 hertz to 20 kilohertz. With these parameters, they are easy to install, and listening to music with them is a pleasure. The speakers also do an excellent job of adding an overall musical picture with bass. The output of the bass is quite dense, and the distortion in the low-frequency bands does not exceed 0, 5%, which is good news.

The speakers of the UltraMarine series are made of polypropylene with excellent characteristics and have a high quality of workmanship. This combination makes them resistant to UV rays as well as water. The design of the decorative cladding prevents the loss of the safety net. Good sound separation is achieved thanks to the built-in tweeter, as a result of which the speakers can be used both for installation in the front doors and for the rear shelf.

  • UV and waterproof materials
  • Convenient for mounting in the front as well as in the rear of the car
  • Crystal clear sound
  • Great acoustics
  • High sensitivity
