Single DIN vs. Double DIN

What is the DIN standard?

A DIN head unit is fitted into your car’s dashboard as a control system for your stereo. DIN stands for Deutsches Institut für Normung – a German standards organization responsible for setting the original standard for car stereos.

It became a worldwide recognized standard after the International Standards Organization adopted it as ISO 7736. Automobile manufacturers continue to refer to the standards even today for all vehicles around the world.

Although ISO 7736 is used to describe the standard car stereo, there are some variants to this. There are two types of DIN head units.

• Single DIN
• Double DIN

Single DIN vs. Double DIN head unit

This section will cover the significant differences between the two head units.

Size

A double DIN head unit is larger. Single DIN head units measure 7 x 2 inches. On the other hand, double DIN head units measure 7 x 4 inches. So, the double DIN head unit is twice as tall as the single DIN head unit.

Cars tend to differ in their head unit receptacle. Some may be small, and others may be bigger. So, it is essential to know the dimensions of the two head units before making the purchase.

Features

The biggest advantage that a double DIN head unit offers is a larger screen display in terms of features. A larger touchscreen makes it easier for the user to control the stereo. Double DIN head units also have more storage space for components like built-in amplifiers.

You can also install additional components in these head units to optimize your stereo functioning. This includes added features like operating backup cameras, DVD player, and HD video display.

Nonetheless, single DIN head units offer just as much functionality with their practical features.

User–friendliness

This is one of the major differences between the two types of head units. As mentioned above, double DIN head units include an array of features. Moreover, the camera and video options and smartphone integration ensure a good user experience.

However, single DIN head units make up for it by being a more practical and convenient choice. While double DIN units have more features, single DIN units can fit a wider variety of dashboards. They have an easy-to-navigate interface with simple and straightforward control panels. If you research single DIN units online, you may come across some models with a good range of features.

Which one is better: Single DIN or Double DIN?

It is not that a double DIN head unit is better than a single DIN head unit in terms of quality. Basic stereo features for sound quality like power and volume settings are the same in both models.

Double DIN units have more room to install more advanced controls. Additionally, if your double DIN unit comes with an in-built amplifier, that will be great for improving sound quality.

The primary factor for you to consider here is whether you want a large touchscreen. A double DIN head unit’s display offers better video quality than a single DIN one.

In all fairness, some single DIN units can be fitted with a touchscreen, which is called a flip-out single DIN head unit.

A single DIN head unit does have some competitive edge over a double DIN head unit. Many tend to side with the single DIN unit simply because they do not want an overcomplicated head unit.

Some people may find the smart technology features in a double-DIN unit harder to control while driving.

You can also take the potential fitment issues into the consideration. While choosing between the two head units, fitting plays a key factor. So, if you are new to the stereo world, you may want to think about consulting an expert. They will cancel out any guesswork to make sure your new head unit is sized properly.

In the end, it will all boil down to personal preference. That is why you will need to have a clear idea of what you are looking for.

Top brands

The make and features of your head unit will depend on what brand you truly trust. Here is a list of brands that stand out in quality and reliability.

Pioneer

Pioneer is an international corporation that was founded in 1938 in Japan. It was started as a humble radio repair and speaker shop by Nozomu Matsumoto. As people came to trust this place, it transformed into one of the biggest companies in the car entertainment industry.

Pioneer is one of the most respected brands when it comes to making and marketing car accessories. The company is known for its originality, with creations like the first automotive CD player and detachable car stereo. Since then, this giant’s popularity has experienced an upward trend.

BOSS

BOSS Audio is an international company designing and manufacturing audio systems. The company has been operational for over 30 years, selling its products in more than 130 countries. Their current headquarters is situated in Oxnard, California.

Pricing

Head unit pricing falls under three different ranges, depending on your budget. This way, you can find whatever single or double DIN head unit you want without breaking your wallet.

Here are the price ranges.

Less than $100

In this range, you will mostly find inexpensive single DIN head units. However, do not underestimate these systems based on their price. They do an excellent job at playing music, compatible with any digital media format like MP3 players. Many of them also work well with Bluetooth-enabled devices.

You may also find some double DIN head units in this range, although they will only have basic features.

$100 to $300

As you can tell, this is the medium pricing range. Here, you will find a wider range of options with more advanced features. These single DIN head units are sleek and high-tech, with a variety of digital media playback options. This includes CDs, DVD players and so on.

This category is not limited to single DIN units. There are also double DIN head units. In this range, double DIN head units will have a high-definition touchscreen, backup cameras, and video and audio playback.

Over $300

This price is typically for double DIN head units manufactured by high-end brands. Such premium quality head units incorporate a combination of car entertainment and navigation features.

Apart from digital media playback, they also offer a range of connectivity options. You can connect it with your smartphones like iOS or Android phones to enjoy their features. Other features include connecting with Wi-Fi so you can enjoy Wi-Fi calling.

Key features

It is crucial that you know beforehand what features you want in your car stereo system. Here are some key traits that you should look out for when buying a head unit.

Power ratings

This is by far the most popular specification that people look at when choosing an amplifier. Power rating helps determine the power of the sound. It tells you how much energy an amplifier can provide to speakers on each power output channel.

There are typically two power ratings given with car stereos:

• Max power rating: Max power rating is the maximum amount of power sent to the speakers without an external amplifier. The car stereo can emit this only for short periods.
• RMS power rating: RMS power rating refers to the power that the head units emit continuously.

Display

The ideal display size should be large. You get a better view of what song is playing and the caller ID when someone is calling. Furthermore, a larger display makes it easier to see the back of your car through backup cameras.

Apart from size, it would be best if you also looked for head units with display screens with a high pixel count. The higher the pixel count, the higher the quality of the display.

CarPlay & Android Auto support

Apple CarPlay and Android Auto allow you to connect your smartphone with the head unit. Then, your smartphone will dictate the functioning of your car’s infotainment system. Newer models of single and double DIN head units are likely to have this feature.

With smartphone integration, you can access all the same apps as you do on your smartphone, such as using Siri, making hands-free calls, and accessing updated maps for navigation.

Connectivity (USB, AUX, Bluetooth/Wifi, etc..)

The clear aim for any current driver upgrading to a modern head unit is seamless connectivity. Under connectivity features comes a wide range of playback options. Playback options refer to the format in which you can play music.

You should check this before you end up buying a DIN head unit that does not support your preferred format. Here are a few critical playback features.

• Auxiliary Port – AUX port lets you connect the stereo with any music device using a headphone connector.
• USB – The USB port is for connecting your phone to the car to play music or charge your phone.
• Bluetooth – You can play your music and operate your phone wirelessly via a Bluetooth connection.

Equalization

Equalization refers to adjusting the frequency component to balance the sound coming out of the stereo. This control allows you to tailor the sound by either lowering or raising frequencies, optimizing your car’s surround sound.

Backup camera support

Rearview video display increases the visibility behind the vehicle. Drivers can accurately judge their position instead of depending on guesswork. So, backup camera input in the head unit is preferred.

Music streaming apps

Streaming music from apps like Spotify and Pandora will make it easier to listen to your favourite music. You put on your favourite playlist with one touch, cutting out the distraction of picking one by one while driving.

Other considerations

Satellite radio

Satellite radio or Sirius XM Radio works like an antenna-based radio, except you need a paid subscription for this. In addition, It offers a clearer signal for better sound. This radio subscription gives you access to a dynamic range of channels. Thus, apart from music, you can also listen to the news, debates, and sports.

Steering wheel controls

The buttons for the head unit must be placed in a way that you can press them while driving. To maintain this safety standard, the best placement option is on the steering wheel itself. That way, you can change music and answer calls without losing your attention on the road.

In-dash GPS navigation

These navigation systems can provide you with real-time traffic data and accurate maps. This feature should not be taken granted for, considering how important it is to know where you are going. Furthermore, it gives your vehicle a more modern and hi-tech look. 

DVD/ CD/ Digital media files

DVD and CD players allow drivers to play music on compact disks. Music on such disks is meant to be played on CD and DVD players. If you burn and download them, the quality of the sound may not come out as great.

So, if your preferred format is DVDs and CDs, then this consideration is especially important for you.

Remote control

The remote control can help you operate the head unit. Many modern head units come with these controllers, including supporting a remote control app. With this app installed on your phone, you can use your phone as the remote to control the unit.

Theft control

Even with a car alarm, many thieves have no problem stealing your stereo without triggering the alarm. That is why you should look for units with anti-theft features. Without anti-theft features, a car audio system is virtually useless to thieves.

Below comes the terminology that you may face difficulties to understanding when searching for a head unit:

Outro

There are certain specifications that you commonly prioritize when it comes to head units. These specifications are quality sound and an easy-to-use interface.

The top pick for a single DIN head unit is Pioneer MVH-S310BT. It trumps the rest with powerful sound quality and a simplistic touchscreen display. What’s more, Pioneer MVH-S310BT completely personalizes the listening experience with added specs.

FAQs

1. Are aftermarket stereos better than factories?

Yes, aftermarket stereos are much better than the factory ones.

Factory stereos can handle the output from a head unit, but cannot achieve the full potential of the sound. You will find yourself constantly adjusting the volume to make the sound clearer. This is because car manufacturers aim to cut costs and do not spring for a high-end stereo.

An aftermarket stereo will show you what you are missing. They provide a clearer quality and detailed audio. Aftermarket stereos also have a variety of tone controls so you can finetune the audio according to your taste.

2. Does changing the car stereo affect the sound?

Car audio systems will not always come packed with extra features to boost the overall sound. They may emphasize one part of the sound, like the treble or bass. You can try fixing the quality with equalizer settings, but that will not significantly differ. For the best surround sound, changing your stereo is a good option.

By upgrading to a new customizable stereo, you can add new speakers, sound deadening material, and a DIN head unit. These components will greatly improve sound quality.

3. Does the head unit matter with the amp?

For good audio, you need the combined power of amplifiers and head units. Neither can achieve peak performance without the other. Both help in boosting the sound signals for better audio.

4. Do you need a head unit for subwoofers?

Factory head units do not come with enough power to drive a subwoofer. Amplifiers come with power that can push the subwoofer. So you can either upgrade to a double DIN head unit with a built-in amplifier or buy a separate amplifier.
