Better sound quality?

Build Quality and Longevity

Apple CarPlay and Android Auto (Wired or Wirless?)

One popular feature in car stereos today is the integration of Apple CarPlay and Android Auto. These systems allow you to connect your smartphone to your stereo and access its features, such as navigation, music, and calls, through the stereo display. When choosing a stereo with this capability, consider whether it supports wired or wireless connections for your convenience.

GPS Navigation

Another popular feature to consider is built-in GPS navigation. This can be helpful for those who frequently travel or have trouble with directions. Some stereos come with pre-loaded maps, while others require a separate subscription fee for updates. Consider your navigation needs and budget when choosing a stereo with this feature.

Steering Wheel Controls

If you want to keep your eyes on the road and hands on the wheel, look for a stereo that is compatible with steering wheel controls. This allows you to adjust volume, change songs, and answer calls without taking your hands off the wheel. Keep in mind that you may need an additional adapter for this feature to work.


When it comes to car stereos, the price can vary greatly depending on the features and brand. Generally, you can expect to spend anywhere from $50 to over $500 for a decent stereo. Keep in mind that more expensive does not always mean better – it’s important to consider what features are important to you and your budget before making a decision.

Look out for Audio Features

The key components of an audio-based Double din unit include a variety of equalizers, retrievers as well as controllers. These parts will help you tailor the stereo system’s sound to your exact specifications. Therefore, the availability and efficacy of these features should form an important point of consideration for selecting your Double Din head unit.

The beauty of today’s Best Double din head unit is its ability to work with a variety of devices, in order to give you the ultimate music listening experience. In this regard, an important compatibility index is the Bluetooth function.

While it is accepted that not all Bluetooth connections are on the same footing, your desired Double Din unit should be able to work with a good number of Bluetooth devices found in multiple devices. This characteristic bears further importance when you want to expand your stereo system with additional speakers or subwoofers.

Power wattage

Power wattage in car stereo is the amount of power that the stereo can output to the speakers. The higher the wattage, the more powerful the stereo will be. There are a few things to consider when choosing a car stereo with the right power wattage. The first is the size of the speakers.

The bigger the speakers, the more power they will need. The second is the type of music you like to listen to. If you like to listen to loud, bass-heavy music, you will need a stereo with more power. The third is the number of speakers you have. The more speakers you have, the more power they will need. Finally, consider how much space you have in your car for the stereo. If you have a small car, you will not need as much power as someone with a large car.


RMS is an acronym for “Root Mean Square” and is a statistical measurement used to calculate the average power of a signal. In car audio, RMS is used to rate the continuous power handling of speakers and amplifiers. It is important to note that RMS ratings are true power ratings and not peak power ratings.

Many manufacturers will list peak power ratings on their products, but these are much higher than the continuous RMS rating and are not a true indication of the product’s power handling. When choosing head unit or amplifiers, always look for the RMS rating to get a true measure of the product’s power capability.

Crossover frequency

Crossover frequency is an important parameter in car stereo systems. It is the frequency at which the sound from the speakers changes from treble to midrange or bass. The crossover frequency determines how well the system reproduces different types of sounds.

A lower crossover frequency means that the system will reproduce low-frequency sounds better, while a higher crossover frequency means that the system will reproduce high-frequency sounds better. The ideal crossover frequency depends on the type of music you listen to and the types of speakers you have.

If you’re not sure what crossover frequency to use, a good starting point is 100 Hz for the bass and 3,000 Hz for the treble. You can experiment with different crossover frequencies to find the setting that sounds best to you.

EQ Settings

Make sure that the double din radio you choose has EQ settings. This way, you can adjust the sound of the radio to your liking.


Being able to control your Double din head unit whilst you drive is one of the most, if not the most important feature for you. So acquiring the most elaborate Double Din unit without being able to effectively and effortlessly engage the functions and menus, is not acceptable.

The versatility of a Double Din unit confers on you the ability to access and control a system’s features without being distracted from the road. The rule of thumb for controls is that fewer, larger, and multi-purpose buttons and knobs are often easier to access and remember than a series of small, single-purpose tools.

Other buying tips you could employ include consulting with current users of the Double din unit you intend to buy as well as going to online platforms like Amazon, to glean customer reviews of the various brands of Double Din Units in the market.

Inputs and Outputs

Choose a double din radio with multiple inputs and outputs. This way, you can connect more than one device to the radio.


Make sure that the double din radio you choose is easy to install. Some radios come with a kit that makes installation easy. Choose a double din radio that fits your car. Not all double din radios are the same size, so make sure to measure your car’s dash before making your purchase.


Can I install a new radio on my own?

Installing a new radio in your car can be a simple DIY task, depending on your level of experience and the specific model of the radio. Some radios require special tools and wiring adapters, while others can easily be installed with just a few basic tools.

If you’re not confident in your ability to install the radio yourself, it’s always best to seek professional help. This will ensure that the radio is installed properly and safely.

Do I need any additional components for my new radio?

In addition to the actual radio unit, you may also need to purchase additional components depending on your car’s specific requirements. This could include a wiring harness, antenna adapter, or dash kit.

It’s important to do some research or consult with a professional before purchasing the radio to ensure that you have all of the necessary components for a successful installation.

Will my new radio work with my car’s steering wheel controls?

Many aftermarket radios now come with the option to connect to your car’s steering wheel controls. This allows you to control the radio without having to take your hands off the wheel, providing a safer and more convenient driving experience.

However, not all cars are compatible with this feature, so it’s important to check if your specific make and model can support steering wheel control integration before purchasing the radio.

Are expensive car stereos worth it?

The answer to this question ultimately depends on your personal preferences and budget. Expensive car stereos often come with advanced features such as touchscreen displays, Bluetooth connectivity, and higher sound quality.

If these features are important to you and you have the budget for it, then investing in a more expensive car stereo may be worth it. However, if you’re satisfied with basic radio functions and don’t want to spend extra money, a cheaper option may suffice.

How do I maintain my car stereo?

To ensure that your car stereo performs at its best, it’s important to properly maintain it. This includes regularly cleaning the exterior and interior of the radio, as well as checking for any loose connections or wiring.

Additionally, be mindful of extreme temperatures and try not to expose your car stereo to direct sunlight or extreme cold. This can cause damage to the internal components and affect its performance.

Are aftermarket stereos better than factory?

Aftermarket stereos often offer more features, better sound quality, and customization options compared to factory radios. They can also be more affordable in some cases.

However, factory stereos are specifically designed for your car model and may integrate seamlessly with other car features. It’s important to weigh the pros and cons and consider your needs before deciding between an aftermarket or factory stereo.

Do you need an amp for an aftermarket stereo?

It depends on your car’s current audio setup and the power output of the aftermarket stereo. Some cars may already have an amplifier built-in, while others may require an external one to properly power the new stereo.

If you’re unsure, it’s always best to consult with a professional or refer to the manufacturer’s recommendations for your specific model and make of car stereo.
