Best Head Units for Sound Quality Buying Guide & FAQ

As we touched on at the beginning of our review, the head unit is like the brain or heart of your audio system. It’s where you control the volume, switch between radio stations, insert CDs or DVDs, or connect your phone to answer phone calls or stream audio. Seeing that it can perform so many functions, you must get the best option out there so you can benefit from all its features.

However, this doesn’t necessarily mean that you should splurge on the most expensive head unit. It’s prudent to arm yourself with proper knowledge of what to expect from the best head unit with the regard to its design, quality, and what you’re looking for in an entertainment system. This will help you save a few bucks while still getting the best head unit. Our buying guide is a great resource for this. 

The Advantages of Owning a Head Unit for Sound Quality

The right head unit can improve sound quality in your car

When designing the vehicle, most manufacturers typically don’t design them with the best audio systems. The stereo and speakers will be just good enough to deliver normal sound. You may notice what you’re missing out on when you play your favorite song, and it doesn’t sound as good as it does in your home theater. The good thing is, most vehicles will give you the allowance of replacing the audio system with a better sounding one.

Head units are designed with built-in amplifiers that help to boost the sound signal being delivered to the speakers. Most also have high and low pass crossovers so the right frequencies can be delivered to the appropriate speakers. This power boost and frequency differentiation help to improve the sound quality, and your overall listening experience.

  • It’s an upgrade from your low-powered factory head unit. 
  • Most come with GPS navigation systems that will give you turn by turn directions to your destination. 
  • Experience better clarity from the audio files you play. 
  • Upgrade the look of the vehicle’s interior with a double-DIN head unit. 
  • It lets you connect your phone to the head unit so you can make hands-free calls.

Popular Types of Head Units for Sound Quality

Car head units are classified according to their height and width. This is what is referred to as the DIN. It’s a standard classification for the body of a head unit. From this, we derive two types of head units: single-DIN and double-DIN. The differences are explained below.


A one-DIN or single-DIN head unit has a front face measuring seven by two inches. These units have a practical design, and they are usually affordable since they come with few controls. They are also quite user-friendly, and some models have a variety of advanced features that help you control the quality of sound.

If your vehicle originally came with a single-DIN stereo, we recommend that you replace it with a similar but modern model since installing it will be easy. It’s also easy to get a single-DIN aftermarket replacement.


A two-DIN or double-DIN unit’s front face typically measures seven by four inches, and you can find slightly larger options with detachable, sliding, or flip out faceplates. The name double-DIN is derived from the idea that it comprises two single-DIN radios stacked together. Double-DIN stereos are fitted with more user-friendly features such as a touch screen, built-in CD/DVD players, built-in navigation systems, and more advanced features that may increase the price of the gadget.

If your vehicle came with a double-DIN head unit, you can carefully remove it, and replace it with a modern one. However, if you intend to replace a single-DIN head unit with a double-DIN head unit, you may have to make a few modifications to the wiring by finding an adaptor that will allow you to connect the new system to the existing wiring harness. 

The Most Important Features of Head Units for Sound Quality

If you want a better stereo, get a better head unit for sound quality

Before buying a head unit, you want to make a list of the must-have features that you want in your head unit. You should then choose head units that fit that criterion so you can build a perfect audio system that meets your needs. Here are a few of the most important features to consider for improved sound quality. 

Power Output 

Most head units typically come with a built-in preamp and an amplifier. The preamp provides the power for controlling basic selections such as volume and sound balance. The amplifier boosts the signal from the preamp so it can deliver a high-voltage audio signal to the speakers, and improve the sound quality. Therefore, you should take note of the amplifier’s rating since it determines the quality of sound that the speakers will receive.

An amplifier that pushes out about 50 to 100 watts can make a huge difference in how the audio sounds. You may not even have to add an extra amplifier to feed more power to your speakers if it pushes out more than 100 watts.   


If you have an older vehicle, chances are that your factory stereo didn’t come with all the bells and whistles that are typical to the modern head units. This is why you should look for an aftermarket head unit with built-in Wi-Fi and Bluetooth capabilities. These features will help you link your head unit with your smartphone so you can make and receive hands-free calls, stream internet radio, and gain access to navigation features.

It will also help to diversify your entertainment options, and instead of only listening to local radio stations, you can listen to music that is stored in your secondary storage devices via a USB or Aux port. Besides that, the head unit should come with outputs that allow you to connect extra amps, subwoofers, and speakers. 

Ease of Installation  

If you don’t have the budget for hiring a professional audio expert to install the head unit, then you should choose a system that’s compatible with your vehicle so it’s easier to install. Prioritize units from popular audio equipment manufacturers; most will have several online tutorials on how to install them, and they also come with detailed installation instructions.

Also, the manufacturers often indicate the type of vehicles their head units are compatible with. If you don’t want to spend a lot of time learning how to rewire your audio system and installing the gadget, the easiest solution is to go for a single DIN unit since installing one is usually painless. 

The Best Head Units for Sound Quality FAQ:

From our buying guide, it’s clear that to redesign your audio system, you need to start from scratch. Instead of buying new speakers, you need to start by replacing the head unit, and then you can work your way up. You can get more information on head units from the question and answer section below.  

Q: Can a single-DIN head unit fit any car audio system?

While not all single-DIN head units are a universal fit for all vehicles, the majority don’t present fitment or installation issues. However, most modern car audio systems come with a double-DIN unit so replacing it with a single-DIN unit will be a downgrade, unless you are going for a minimal design. 

Q: Do head units improve sound quality?

They sure do. Aftermarket head units come with built-in amplifiers that provide more power that helps the speaker to sound better and clearer. They also come with features that help balance the quality of sound so you can experience minimal distortion, and get the best out of the subwoofers and car speakers. 

Q: What is the difference between a single-DIN and a double-DIN head unit?

A single-DIN unit is a smaller stereo that measures seven by two inches. It has a minimal design with just enough functions to give you a comfortable entertainment experience. In contrast, double-DIN units are larger and typically measure seven by four inches. They come with more features that not only improve your entertainment experience but help you drive safer and more comfortably. 

Our Top Pick

The Pioneer AVH-200EX Multimedia DVD Receive tops our list because it delivers enough power to make stock speakers sound better. It also has a sleek and aesthetically appealing design with a clear display and easy-to-read graphics. It can help transform the look of your vehicle’s interior, and at the same time expand your entertainment options. 

Final Thoughts

While the Pioneer AVH-200EX Multimedia DVD Receive may be a decent pick, it’s not the most affordable head unit out there. This is why we also recommend the Alpine CDE-120 Car Stereo Receiver if you are looking to save a bit of cash. It has a simple single-DIN design that’s easy to install on any vehicle. It also helps to deliver excellent sound and comes with an equalizer so you can control the sound.
