Many opt for an Apple CarPlay head unit nowadays. This is essential since the best car speakers in India can dramatically change how you feel while driving. However, it would be best if you ideally had a grip over the right head unit size. Furthermore, pick the correct head unit size that will fit your car precisely when purchasing top car accessories

Fortunately, car stereo professionals have created this guide to assist you in determining the correct head unit size for your vehicle.

The Factors

Consider several factors if you want to improve your car’s entertainment system. First, however, remember that an aftermarket head unit can significantly alter your driving. 

The following are some of the critical considerations when buying a head unit:


Speaking by the book, practicality is essential when replacing a car audio system. Undoubtedly, anyone can create a great sound system by putting bucket loads of cash. However, most people don’t necessarily have that option. So figure out your needs, requirements, and any extra components before choosing a head unit that fits your budget.


Then again, the car stereo’s design and feel are also important. You essentially go through all the features before choosing a head unit. This will ensure you get the chance to see whether you like them. Next, try using the buttons and knobs to navigate the user interface, menu, operating system, and controllers. 

Your Own Car Head Unit Measurement

Do note that most head units don’t promise universal compatibility. Thus you must ensure that your preferred head unit will fit securely into your car’s dashboard. Determining the correct head unit size for your particular needs should only be left in the hands of automotive stereo experts.

Looking at the online market, you can find several universal head units with universal suitability to fit vehicle radio dashboards. However, it is crucial to use caution and ensure the head unit will check your car securely and safely before buying.

Most experts recommend measuring your head unit by hand. Fit databases and lookup tools are typically fairly accurate. Moreover, you can remove a lot of the uncertainty by comparing them. 


Your head unit will provide power as the audio output to your speakers. To put it simply, more power suggests louder sound and less distortion at mid and high-volume levels. However, it is necessary to mention that pairing a solid head unit with subpar speakers won’t yield great results. 


The appearance of a head unit is more important to some people than others. If you are one of them, you must ideally choose a head unit that doesn’t look garish. This is essential since it typically serves as the dashboard’s focal point. In other cases, you may prefer keeping the original head unit in place for aesthetic reasons.

To Identify the Correct Head Unit Size, Use an Online Database

If you are a first-timer, do note that finding an online database for car stereos is the key to identifying the correct head unit size. The database will tell you if your car supports single DIN, double DIN, or other size of head units. In addition, you will need to enter your vehicle’s make, year, and model. 

Sound Sources

Then again, it is necessary to mention that the most significant head unit audio sources depend on personal preference. This is since everyone has a different number of cassettes, CDs, MP3s, and other digital music files. You might want to seek a head unit that can play the following, depending on your collection:

  • Portable Discs
  • DVDs
  • USB
  • DVDs in Blu-ray

However, you may also look for a mechless head unit if you have digitally preserved your whole media library. Simply put, Digital media receivers, or mechless heads, have modern features like Bluetooth and HD Radio in addition to standard car radio features. But there are no moving parts in them.

Since these head units don’t have moving parts, people refer to them as “mechless.” They can’t play CDs or cassettes, but you can play music from internal hard drives, SD cards, and USB sticks.

Final Verdict

There’s no denying that correct head unit size can significantly enhance your sound quality. This holds even if you don’t replace your entire sound system at once. You can also benefit from the numerous practical additional technological features that today’s head units provide.

Install from the best specialists, since it is essential. The most excellent factory-trained fabricators offer the ideal installation for listening to crystal-clear music.
