What Is a Single DIN Head Unit?

DIN head units are the devices located in the center console of most cars, that are typically used to control the volume of a car’s stereo system. Single head units are about an inch long, allowing more space in the console for storage or other devices than the larger double head units.

In addition to determining the amount of power sent to the speakers, aftermarket head units can pair with smartphones and other input devices to allow for streaming music and hands-free interfacing with select Apple and Android apps.

What Are the Advantages of Upgrading a Head Unit?

Upgrading a car’s head unit increases the potency of its speakers, the expandability of its audio system, and the number of small tasks that can be handled through one readily available interface. Aftermarket head units universally provide more power, more inputs, and more overall capabilities than their factory-installed brethren.

On both an aesthetic and functional level, installing a new head unit noticeably improves a car’s capabilities.

Considerations for Choosing the Best Single DIN Head Unit

Given the huge amount of DIN head units available, individuals are better off deciding on their personal wants and needs and narrowing their search by that criteria. Supported media, consistent average power, and expandability are important factors for audio enthusiasts while smartphone integration and personalization features are for those who want to enhance their overall driving experience.

  • General Features: Much of how a head unit performs is determined by its core features. The power output of the amplifier, supported file-types, and customization options play an important role in how well a unit performs and fits in with a car’s interior. Amplifier power is especially important for people who are planning on upgrading their speakers as well.
  • Audio Features: Head units can do a lot to affect audio playback, provided they have the right built-in capabilities. The presence and effectiveness of equalizers, retrievers, and additional controllers contributes to an individual’s ability to personalize their car’s sound quality.
  • Compatabilities: The most basic input a modern head unit can have is AM/FM radio and a CD player. Even something as simple as an auxiliary input gives people the opportunity to use their music players and phones as additional sources, and Bluetooth integration allows the same to happen over the air. Head units that support Bluetooth present unique and convenient benefits such as hands-free calling.
  • Controls: Ease-of-access is of the utmost importance while driving, so this guide takes into consideration how easily each head unit’s features are to access and memorize. Simpler interfaces are less likely to be frustrating, as most people would like to be able to skip songs, adjust volume, or take calls without having to take their eyes off of the road.

Audio Features

Pioneer DEH-150MP

It is aided by an advanced sound retriever that enhances the quality of compressed file formats commonly used for mobile music by restoring the clarity and brightness of high notes. For fine tuning, the 150MP features a 5-band equalizer. People who enjoy multiple genres of music may find the lack of equalizer presets cumbersome, but more generalized settings still add a substantial amount of punch to each track.

The KDC is one of the better performing amp heads on the market. Its power handling allows speakers to deliver stronger audio, further augmented by a 3-band equalizer with 8 optimized preset curves.

The 150MP is limited to a single front-panel auxiliary input, but for most music players this is enough to get the job done. There isn’t an audio device in the world that doesn’t have a headphone jack, so the 150MP can make good use of its singular input. It has a respectable 2-channel preamp output for rear speakers or a subwoofer so one can add more output devices, but further upgrades would be better served by a head with more capabilities.

Kenwood KDC-HD455U

The KDC can’t communicate wirelessly, but it can interface with iPods and smartphones via cable. Through it, one can access stored media or online radio stations. The head integrates nicely with the Pandora app for iPhones, allowing individuals to control the app without fiddling with their phones.

The 150MP’s control scheme doesn’t require many buttons or knobs to access all of its features, so the overall design of the head is relatively compact.

The head comes with a remote control for back seat DJs.

Kenwood KDC-HD455U

The KDC is one of the sleekest looking receivers available. It has a polished aesthetic, not too many buttons, and a clearly visible screen. The buttons are a little small, but with habitual use, one won’t expect to have too much trouble with them. The onboard menus are generally easy to navigate, but the iPod menu specifically can be complex for devices with a high volume of songs. The remote is a nice size and has access to a broad range of features.

Pioneer DEH-X9500BHS

The X9500BHS is very intuitive, making efficient use of several multi-purpose buttons for easy access. The intelligent placement and pairing of the buttons make it very easy to get to desired functions, even when only making an educated guess. The screen’s menus are well organized and easy to read at a glance, so very little time is spent looking back from the head to the road. Operations that seem complex on other units play out so easily and naturally through the X9500BHS’ interface, it calls into question why its design isn’t more commonplace.
