Curious about what double DIN means? DIN stands for Deutsches Institut für Normung, which means the German Institute for Standardization. It sets up rules for the standardization of different products, including car radios. In turn, manufacturers all over the world follow these standards.

The current standards for sizing of radios began in 1984 under DIN 75490. Later, it had revisions under ISO 7736. It was a rule under the International Organization for Standardization,

According to its requirements, a DIN radio has a height of two inches and a width of seven inches or 180 x 50mm. Meanwhile, it does not specify the length. These specifications are made to fit in most head stereo units of different car brands and models.

Meanwhile, as the name implies, a double DIN car radio is twice the size of a standard DIN radio. While the width is also seven inches, the height is four inches. In metric dimensions, the measurements are 180 x 100mm.

So, a double DIN stereo refers to a standard radio size that has been defined by a German-based organization. It seeks to improve efficiency and establish consistency amongst car and radio makers around the world.

Should You Choose a Single or Double DIN Car Radio

The answer will depend on the radio that your car currently has. If your car comes with a single or standard DIN radio, then it means that you can use only the same radio. This is what will fit in the provided space. On the other hand, if it has a double car stereo DIN, then such is the only appropriate replacement.

With the differences in size, you can also expect variations in features. If you want something cheap and simple to use with basic features, then a single DIN radio is a good choice. On the other hand, if you would rather have something bigger with more functionalities, then it is hard to go wrong with a double DIN stereo.

For punchier music, RMS power and peak power are two of the most important considerations. However, make sure that they match with the other parts of the car’s sound system.
