What does DIN mean and stand for? What's the difference between Single DIN and Double DIN when it comes to stereos, receivers, and in-dash dvd players?
DIN is the standardized size for car stereo head-units. Universally adopted in the 1980s it comes from the German Institute for Standardization or Deutsches Institut für Normung, hence DIN. The size refers only to the face of the unit not to how deep it is. A Single DIN stereo is roughly 7 inches x 2 inches (180mm x 50mm) and is the common size for a deck containing a single slide in CD player. Double DIN is the same width (7 inches) of single DIN but is twice the height making it 4 inches tall. Double DIN is most commonly seen in stereo units that have more elaborate displays such as small in-dash dvd players.
