Tip: When replacing the serial radio in Honda Accord, you can use a Double DIN radio for all cars produced between 1990 and 2015.

For Accords older than 1990, you can install only a Single DIN stereo, but it does not mean that you have to sacrifice a large screen in the car.

An excellent example of a Single DIN radio with a flip-out screen is the DVD receiver Pioneer AVH-3500NEX. Or, if you prefer a floating screen but no DVD option, I recommend checking out the BOSS BCPA10. You will get excellent sound quality with both, but BOSS is less expensive.

In this article, I will cover everything you need to know about how to upgrade the stereo in popular Honda Accord models.

Pros of Upgrading the Stereo in Honda Accord

The factory stereos that come with cars are usually pretty basic, and they may not have the features you want, especially if your Accord is not equipped with the premium stereo.

For example, your car can play AM/FM radio, but you want to listen to the HD or Satellite Radio. Or maybe your car stereo is fine, but it doesn’t do an excellent job of reproducing music from your MP3 player or smartphone.

There are many good reasons to upgrade your car’s stereo, and below I listed some pros of upgrading the factory car stereos:

Improved Sound Quality

The most obvious reason to upgrade your Honda Accord stereo is that you want better sound quality.

If you’re still listening to the stereo that came with your car, you’re missing out on the impressive advances audio technology has made in recent years.

Aftermarket stereos offer improved clarity, loudness, and bass response, giving you the best out of your favorite music.

GPS Navigation

Many aftermarket stereos have built-in GPS navigation systems that allow you to find destinations without pulling out your phone or using a separate device.

Bluetooth Connectivity

Bluetooth audio streaming allows drivers to connect their phones wirelessly to listen to music or take hands-free calls while they drive.

Satellite Radio

If satellite radio is important to you, make sure that your new receiver has either built-in satellite radio capability or the ability to add it as an option later on.

HD Radio

HD Radio delivers better sound quality than regular AM/FM radio broadcasts by sending digital data along with the signal. The HD Radio logo on a receiver indicates built-in HD Radio capability.

CD Player

If you want to be able to play burned CDs and MP3 or WMA files. You need a CD player that can decode and play many different music formats, like MP3 or WMA.

Display Customization

Some aftermarket head units allow users to customize their colors or select from different display backgrounds.

Cons of Upgrading Car Radio in Honda Accord

You might have invested a lot of time and money choosing the right stereo system for your Honda Accord, but the effect was not what you expected.

Below are some cons to upgrading the stereo in your car:

Alarm Integration

Upgrading the factory stereo system in Honda Accord will cause it to become disconnected from the vehicle’s alarm system.

The factory-installed stereo system helps protect your vehicle from theft by integrating with the car’s security system.

Unfortunately, when you upgrade your sound system, you have to reset the alarm system, and the new radio will not be connected to this important protection feature.

Disconnecting Airbags

When installing a new stereo, you will have to disconnect many wires from your dash, including the airbag wiring.

If you don’t know how to do this properly, you could permanently disable the airbag, so getting the professional involved in the radio replacement process may be necessary.

Battery Drain

A high-quality sound system requires more power than the factory stereo that came with Honda Accord.

Although you will not need a stronger battery just for a new radio, a larger or additional battery may be required when you add an amplifier to the Accord sound system.

Lack of Expertise

Even if you’ve successfully upgraded a car’s stereo before, each vehicle is different and has unique features.

If you attempt to install the new stereo yourself but run into trouble, it can take longer than expected, and you won’t be able to listen to the new system until it’s working correctly.

If this happens frequently, the amount of labor involved could exceed that of having someone experienced with installing stereos do the work for you.


Another disadvantage of upgrading your stereo system is how expensive some components are.

For example, while a typical CD player with an iPod interface should not cost you more than $200-$300, a satellite radio receiver with a top-class capacitive screen and GPS navigation system may cost $1,500 or more.

What Tools Do You Need to Upgrade Stereo in Honda Accord?

When you purchase a new car stereo, you quickly realize that you need specific tools and supplies to complete the installation in the car.
