Most head units come with 80- to 100-watt channels and amps to give you a better sound quality even without having to upgrade your factory speakers. 
  • Multiple connection options. Most head units can connect to other devices via USB cables and AUX cords. With Bluetooth and Wi-Fi connectivity, you can play your favorite music from your iPod, iPhone, and other MP3 devices. You could also stream satellite radio with SiriusXM or stream online music from Google Music, iHeartRadio, and Spotify.
  • Upgrade your vehicle’s look. A new head unit is a great way to customize the look of your car to suit your taste and preferences. A head unit with a clear display will improve the look of your dashboard and add a personal touch that reflects your personality and sense of style. 
  • Phone connectivity. Most head units are compatible with iOS and Android devices. You can enjoy hands-free calls or play music from your phone via Apple CarPlay or Android Auto. Additionally, you can connect the navigation feature in your phone to the head unit for a better view of unfamiliar locations. 

Types of Head Units


Single-DINs typically come in sizes of 7 by 2 inches. The unit typically fits into the dash of most standard vehicle models. These head units are popular because they are inexpensive and have easy-to-use controls.


Simply put, double-DIN head units are twice the size of the single-DIN units. These head units come with more advanced controls and features. Most have touch screens for easier operation, can play videos from auxiliary storage devices and can be used to operate backup cameras.

Head Unit Pricing

  • Under $100: In this price category, you will mostly find single-DIN multimedia players. These are essentially great for playing music from Bluetooth-enabled devices and digital formats. You might find some double-DIN head units, but they will have more basic features.
  • $100 to $300: This price range is full of high-tech single-DIN stereos that are sleek in looks. These units can play CDs and DVDs and offer a wide range of playback options. Also in this category, there are double-DIN head units that have advanced features; most come with high definition touch screens.

Key Features

Power Rating

In the absence of an amplifier, the car speaker’s power will depend on the stereo’s power output. In this case, you should focus on the deck's RMS rating and watts per channel. The RMS power rating refers to the power the head unit can give at a constant rate. Additionally, higher watts per each channel essentially means that the head unit will produce enough power for the speakers without using an amplifier.

Display Size

Modern head units typically come with a clear display. Basic single-DIN units have a small display, and a large touchscreen display is common with double-DIN head units. Large displays give you a better view of the music that is playing, the caller ID, and what’s behind the car through the backup camera. You can take the experience to another level with a touchscreen display or a folding screen that’s common on single-DIN units.

Playback Options

Playback options refer to the methods used by the head unit to play music. Some of the common examples include DVD, CD, HD Radio, MP3, Auxiliary ports, Bluetooth, Pandora, and Wi-Fi. Fortunately, most modern units offer a wide range of playback options and connectivity features that will give you access to all of your music and videos.

Other Considerations

  • Sound Quality: Go for a unit that provides the best sound quality in its price range. It’s also a good idea to choose a unit that allows for the addition of an equalizer, digital sound process, and amplifier for better quality sound.
  • Smartphone Compatibility: Most new head units will allow you to integrate your smartphone, and this will give you access to online streaming applications such as Spotify and Pandora. Smartphone integration also allows you to make hands-free phone calls and to use the maps in your phone for navigation.
  • Expandability: Look into how far the head unit can stretch when it comes to connecting to external components. These external components may include speakers, rear and front view cameras, microphones, and other video and audio outputs for a better listening experience.

Best Head Unit Overall: Pioneer AVH-3300NEX

Pioneer AVH-3300NEX

The Pioneer AVH-3300NEX is a single-DIN car head unit with a 7-inch slide-out VGA touch screen. When you turn off the ignition, the screen slides back into the unit. The screen comes with five display colors, 13 splash screen options, and an automatic dimming feature. The unit also features an 800 x 480-pixel resolution and a microphone for hands-free calling and voice commands.  

The AVH-3300NEX supports Apple CarPlay, Android Auto, and AppRadio Mode that all allow you to control compatible smartphone applications using the touchscreen (you will need to buy an interface cable for this). The head unit has controls for Spotify, Pandora, and Apple Music. In addition to online streaming music, the unit can also play music from AM/FM radio, USB, CDs, and DVDs. It also comes with built-in Bluetooth and features good control menus.

The unit comes with small buttons that might make operation difficult when you are driving. The slide-out screen might block important car controls if they are located above the unit.

Best Value Head Unit: BOSS Audio BV9362BI

BOSS Audio BV9362BI

The BOSS Audio BV9362BI is a double-DIN head unit that has a wide range of features all rolled up into one inexpensive shell. This unit comes with a 6.2-inch LCD display with touch controls for different functions. The device features audio streaming and Bluetooth connection for hands-free calling when paired with smartphones. The wireless music streaming function supports services from Pandora and Spotify.

BOSS Audio BV9362BI supports SD memory and USB flash drives of up to 32 gigabytes. You also get an auxiliary input that supports the connection of audio devices such as smartphones and MP3 players. Its unique feature is the steering wheel control integration, coupled with rear camera input. This feature will automatically switch the screen to the rearview camera as you shift into reverse.

However, the unit has a complicated design that consequently complicates the general operation of the device. You might have to wait sometime before the head unit starts and even longer when loading a song playlist. In addition, you may strain when using the remote; you have to align it directly to the stereo, which beats the purpose of a remote controller.

Best Head Unit Honorable Mention: ATOTO A6 Double-DIN Android Stereo

ATOTO A6 Double-DIN Android Stereo

The ATOTO A6 is a double-DIN android stereo that comes with navigation and entertainment features. This unit runs on the widely used Android Marshmallow operating system. It features quick-booting technology, which allows the user access to the device within two seconds after starting the car. It also features dual Bluetooth chips that work as internet tethering connections as well as hands-free calling units.

It’s one of the best head units when it comes to USB support since it supports devices of up to 256 gigabytes of storage. It also has three USB interfaces for USB drives and one micro SD card slot. This unit comes with backup camera input, auxiliary audio and video input, and an audio and subwoofer output. ATOTO constantly updates the firmware by adding new features and dealing with bugs.

A major drawback of the product is its incompatibility with some steering wheel controls. You would have to buy a special adapter to connect the head unit to the steering wheel controls. Moreover, the stereo automatically turns on every time you turn on your car; that's an annoying feature, especially when you don’t want the noise from a stereo. It also has minimal touch sensitivity around the corners.

  • Replace your car factory speakers when you get a head unit. Speakers are often not a priority when vehicle manufacturers are designing cars; most don't have great sound quality. When you get a high-quality head unit, you should pair it with strong speakers that will handle the power output of the stereo.
  • Always play high-quality audio and video tracks; you will then enjoy the full potential of the head unit and feel every high and low frequency of the audio.
  • Get an amplifier. Amplifiers will make a mediocre head unit better by amplifying the sound and minimizing distortion. It will also give you a better sound range and control over the sound output. 


Q: Which type of head unit should I buy for my car?

A: The first things to consider are the size of your factory stereo and the space available on the dashboard. These will determine whether you get a single- or double-DIN head unit. Once you have an idea of what you are looking for in terms of size and features, decide on the price range, buy a head unit, and have a professional help you install it.

Q: Can I upgrade from a single-DIN to a double-DIN head unit?

A: Yes. It is possible to change from a single-DIN unit to a double-DIN unit in some cars as long as there is ample space for the upgrade. Double-DIN devices will require double the size, and that may require a professional to fit it into the dashboard without blocking other controls. 

Q: Will I lose some functionality out of my vehicle after installing an aftermarket head unit?

A: If your factory stereo system controls important steering wheel functions like the horn, then you may risk losing the functions. But there is a way around it. You could ask a professional to connect the head unit to the steering wheel controls with a special adapter to preserve the functions.
