We think that sound quality has to be up there as one of the most important factors to think about. Afterall, what is a road trip without the best music?

Check out our double DIN head unit review for our pick of six of the best when it comes to sound quality:

Best Sound Quality: Pioneer AVH-W4400NEX In Dash Multimedia Receiver with 7″ WVGA Clear Resistive Touchscreen Display

In the search for the best double DIN unit for sound quality, we start with the Pioneer AVH-W4400NEX In Dash Multimedia Receiver with 7″ WVGA Clear Resistive Touchscreen Display. It’s quite a mouthful, but this unit packs quite a punch.

First up, you get a seven-inch motorised display, which can be detached and stored safely in the provided pouch. Next up, you get several built-in modes of connectivity. These include Bluetooth and Siri eyes free. The unit also connects to two phones at once so you and your driving partner can make and answer phone calls, as well as stream audio. The unit also has built-in controls for iPhones, iPads and iPods. There are two USB ports in the unit – one for Apple devices and one for Android – meaning you don’t have to rely on Bluetooth for connecting your phones.

If you don’t want to play music off your phone, you can use one of the many other options that come standard with the Pioneer. You get the classic DVD and CD player, as well as a car radio app so you can tune into your favourite local stations.  In addition, the unit also has Spotify so you can make your ultimate driving playlists and then log in to get them whenever you hit the road.

And now for the most important element of this review: the sound quality. Pioneer is known for high-end products with excellent sound quality and this one is no different. It offers built-in amplification that keeps sound true. This model also has a 13-band graphic equaliser that can hold two custom curves. The sound quality is pretty good over Bluetooth if you’re streaming from your phone, but it really comes to life when you plug your phone in or use one of the native ways to play music or other audio content.

As an added bonus, when you get this unit from Amazon, you also get a magnet phone holder so that you can keep your phone handy when driving. You also get an HD backup camera to make reversing and parking that much easier. The rear view from the camera will come up on your unit’s display.

Best Overall: Sony XAV-AX5000 Car Stereo Double DIN Radio 

Up next, but honestly in no particular order, we are looking at the Sony XAV-AX5000 Car Stereo Double DIN Radio with Apple Carplay, Android Auto, Bluetooth, 7″ Screen + SXV300AZV1 Connect Vehicle Tuner Kit for Satellite Radio with Installation Tool. Another mouthful, but also another powerful and reasonably priced unit. In this bundle offer, you get the Sony unit plus a Connect Vehicle Tuner Kit for Satellite Radio. It also comes with a free three-month streaming subscription through Prime. This added extra is great for those who love their music and want as much access to their favourite tunes and opportunities to explore new songs and artists – all without running down the battery of your phone through streaming.

When it comes to sound, this unit has a feature that a lot of drivers love: physical channel buttons and a physical volume dial. This seems super old school, but it really works. You have to look at a touch screen to press those “buttons” and that can be quite distracting while driving. Having something physical that you can find by feel is a lot safer while out on the road. A physical sound dial also gives you great control while driving.

The actual sound quality of any audio played through the Sony unit is exceptional. Whether you’re using your phone to stream or you’ve plugged your audio source directly into the unit, it offers an excellent listening experience. What’s more, this unit has become a favourite with those who want to pair a double DIN with Android or with iPhone. This Sony is compatible with both Android Auto and Apple Carplay, making it a universally flexible option.

Sony has been making audio-visual tech for years, so it’s hardly surprising that this double DIN head unit has exceptional sound quality. It’s also a highly responsive unit, allowing you to adjust sound levels for both playback and phone calls with ease. You can go all the way from -8 dB up to 18 dB to get the detail you want out of the audio you’re listening to. There is a 10-band equaliser built into the unit, which gives you plenty of control to increase and decrease various frequencies to get just the right sound for your audio playback. The unit also syncs quickly with your phone after starting your car, so you can start playing music or audiobooks quickly and easily.
