Best Double Din Head Units 2018 – Greatest Speakers

It’s all to do with the size. As I mentioned at the top of the article, DIN is a standard measurement for car radios and head units. Most cars have either a single or double DIN slot for the head unit. You can tell the difference when you look at your head unit’s faceplate. Both single and double-DIN units will be about 7 inches long. It’s the height that’s the key difference. Single DIN units are only 2 inches tall, whereas a double DIN unit is 4 inches tall. You tend to see a lot more touchscreens built into double DIN units because of this extra height.

Single DIN units are only 2 inches tall, whereas a double DIN unit is 4 inches tall. You tend to see a lot more touchscreens built into double DIN units because of this extra height.

You can install a single DIN unit into a double DIN slot. But, you’ll need a special installation kit for the job, which is a hassle that I personally don’t want.

So, which is better? Double DIN units have a distinct advantage because of their size. You’ll find they have bigger screens and often have more powerful amps built into them. But, that doesn’t mean that a double DIN head unit is always better than a single DIN unit. A lot depends on the manufacturer. You’ll also find that many single DIN units still suit your needs if you’re looking to connect them to external amps.

You might see some head units that come with a “peak power” rating. This shows the highest power level that the amp or speakers can handle. Do not let this rating fool you. While it will be accurate, it’s also misleading. The peak power is something that your amp or speaker can’t maintain for long periods of time. That’s why it’s often four or five times higher than the RMS.

I’ve covered the key features a lot of people look for from their head units, namely device connectivity, touchscreens, and navigation. But, you’ll have noticed that a lot of the units I’ve looked at have plenty of other features as well. In fact, the best double DIN head units tend to come with an array of additional features for you to enjoy.

Let’s start with the basics. You’ll find some units have CD and DVD players. You might see these as relics of a bygone age, especially given how easy it is to stream music and movies these days. But, these players offer you another option. For example, your device may run out of charge or you might drive through an area with low signal. This will prevent you from streaming. That’s where a CD/DVD player comes into its own.

Still, it’s not a huge issue. Most head units in modern cars have all of the features you’ll find in external units, plus a few more specific to the vehicle. More often than not, you’ll find these head units suit your requirements. You really only need to look for another one if you’re driving an older vehicle or your current head unit is broken.
