How to Buy the Best Single Din Head Units

How To Buy The Best Single Din Head Unit

1. Power

Power is a crucial factor to consider before buying a new head unit, as is a determines of how well the unit will provide audio signals to the speakers.

Head unit power is measured in watts, and there are often two ratings, which are the peak and RMS power. Peak power is the maximum power that the built-in amplifier can reach, while the RMS is the actual average power getting to the speakers at all times.

A single DIN unit with at least a 200-watt power rating is often good enough. However, something that delivers even more power like the 300-watt Pyle PLMRB29B is better for those who prefer highly powerful sound outputs.

2. Display

Since single DIN head units are small in size, it is natural to assume that all have small screens. However, this is not the case. Some single din stereos have large screens that flip in and out of the unit, effectively giving you a 2 DIN size screen from the small unit.

Therefore, if you fancy having a large screen with its accompanying features, yet you have a single DIN slot in your dashboard, It is still possible to get something with a larger screen like the 1.5 line display you get on the Kenwood KDC-BT375U.

Besides screen size, it is also essential to make sure that the backlighting is good to see well even in the dark and that the display uses a font that is easy to read.

3. Playback

Stereos are for car entertainment. As such, the best head unit should have USB ports, Bluetooth connectivity and CD players that can play at least MP3, and WMA audio formats as well as MP1, 2, and 4 video formats.

Most songs are available in these formats, and so to ensure you can enjoy them, your head unit needs to be able to read the file.

Since you cannot be certain of all the exact file you will need to play, it is always better to go for a multimedia unit like Pyle PLMRB29B and most others on our review.

4. Expandability

The expandability of a head unit depends on the input and output ports. A head unit with multiple I/O ports is better because it is easy to expand. For instance, having RCA outputs allows you to expand the sound system with amplifiers and subwoofers.

On the other hand, a camera input enables you to expand the stereo's capabilities to improve your driving experience, as you can use it to mount a monitor for your reverse camera. This input makes the head unit useful for more than just listening to music.

5. Connectivity

When it comes to connectivity, the more options, the better as they ensure you can connect your head unit to almost any device. But, here are the three main connectivity options you need to make sure you get.

  • Bluetooth: A built-in Bluetooth functionality enables you to make calls hands-free and stream music wirelessly. Apart from being convenient, Bluetooth also ensures safer driving.

  • USB: USB also allows for music streaming via a USB cable and converts the stereo to a charging system for your other devices like smartphones and tablets.
  • Aux: Auxiliary ports are basically "reverse" headphone jacks. They take input from the connected device (headphone jacks provide output) and play it on the car speakers.


With the best single DIN head unit, you can easily take your car's sound system without having to spend much. Regardless of your preferences, there is a good model for you on our review above.

That said, the Pioneer DEH-S1100UBis our best overall model and top recommendation. Besides delivering exceptional sound quality, this unit works with most handheld devices and is packed with various other fantastic features.

However, for motorists looking for something more budget-friendly, the BOSS Audio Systems 616UAB will be a more appropriate choice.
