Single-DIN vs Double-DIN Head Unit: What's the difference?

by marketing gt 08 Jul 2024

What does Double DIN mean?

When buying a car stereo, you'll come across the term "DIN size" early on. A concept that might be something you've never heard of before. Don't worry, most people haven't.

In layman's terms, ‘Double DIN’ or ‘2 DIN’ is a term coined to specify a measurement. A standardized size for a car stereo, radio, or head unit.  

DIN size refers to the size of the stereo's chassis, and car stereos come in two standard sizes:

  • Single-DIN refers to stereos that are two inches tall (and seven inches wide)

  • Double-DIN refers to stereos that are four inches tall (and seven inches wide)

Nowadays, the vehicles can accommodate either size, both sizes, or both.

Why won't a double-DIN stereo fit in my car? 

These days, your factory radio might have a double-DIN screen or control panel, but the chassis might be much smaller. More importantly, the opening in the dash might be designed to only accommodate that smaller chassis. A double-DIN replacement won't fit.

There are some aftermarket stereos that have a similar design. Once you tell us about your vehicle, we'll be able to show you all the stereos that will work in your car. 

Why was Double DIN introduced?

German car manufacturers set a standard size of 178mm x 100mm for car stereos. This standard size was established to simplify the production process for car stereos. The goal was to make it easier to create stereos that could fit into different car models worldwide.

This standard includes both single DIN and double DIN units, with double DIN units being twice the height of single DIN units. The larger size accommodates enhanced power, performance, and additional features like digital displays. While the width and height were standardized, the depth was left unspecified, allowing for design flexibility.

Get the installation gear you need

At Gtzone, we prioritize two things:

  • Make sure all our customers know which car stereos will fit (and work in) your car, and

  • Once you choose a new stereo, make sure that you get all the right things you need for installation.

Most of the time, you'll also need a wiring harness to help with all the connections. Many vehicles also need CanBus adapters to make the stereo work safely with your car's electronics.

When you shop with GTzone, we'll send you all the installation gear you need. If there are multiple options available, we'll tell you and also tell you the differences between them. In most cases, our head unit upgrade kit packages are extremely easy to install, simply a straight swap and plug and play. Click here to browse head units.
