What Size Are Speakers In My Car?

Speakers come in many sizes to fit different cars. Here are the common choices.

3.5 inches Speakers

Speakers of this size are small and suitable for vehicles that can’t work with big speakers. Each model has a subwoofer and tweeters to produce sound.

These models lack a larger cone. Hence, they can’t deliver a robust bass wave. Instead, they’re excellent for midrange because a subwoofer-equipped car speaker covers the gaps.

4 inches Speakers

The 4-inch speakers are only a little bigger than the 3.5-inch versions, but they have higher audio quality.

These models don’t do a great job in lower ranges. However, their powerful mid-bass is robust, making them a perfect choice for car stereos. 

After all, they generate the best sound range, especially when paired with a larger vehicle speaker. 

5.25 inches Speakers

The 5.25-inch drivers are a big step over the 3.5-inch and 4-inch versions in the mid-bass. This size is also among the most popular choices. 

The devices have more outstanding bass, great sound, reduced distortion, and a wider range of frequencies. As a result, many drivers install a 5.25-inch driver in their car stereo.

6.5 inches Speakers

The 6.5-inch models can work with many vehicles and are compatible with any vehicle model. 

Speakers of a larger size bring many benefits, including higher sound quality, increased music listening experience, and fantastic bass.

6.75 Inch Speakers

These speakers offer a great sound experience, with minimal distortion and high power output. In addition, they are built to last, meaning that you’ll enjoy your music for years to come. When shopping for 6.75 inch car speakers, be sure to compare features and prices to find the best deal.

How To Choose The Right Car Speaker?

We have discussed the five options to install in your vehicle. But how to tell which one works best for you? Please follow the steps below to discover.

Check your vehicle’s model.

Although speaker sizes are uniform across the industry, different car makers may offer devices with somewhat different dimensions. 

As a result, double-check the speakers’ dimensions before purchasing them and make sure they can fit appropriately after placement.

Check the speaker’s size.

Before determining which speakers will fit, remember to check their dimensions and the size of the installation site. The two measurements should match for a snugly-installed speaker.  

Thankfully, the measuring task is simple. All you have to do is get a measurement tape and follow this guide: 

  • Remove the panel from the vehicle’s door. For many automobiles, you can locate your speaker there. 
  • Measure the mounting length, which refers to the gap from the mounting plane’s base to the speaker’s magnet. 
  • Measure the diameter of your desired speaker. 

Purchase brackets

Buy brackets while purchasing automobile speakers. The brackets can help when the mounting panel can’t fit the speaker size.   

Can You Use Car Speakers In A Different Size?

Yes, you can replace an original speaker with a new one of a different diameter. In this case, you’ll need to take accurate measurements to guarantee that the setup is secure and robust.

However, if the original devices are not of the typical speaker size, you can try the following tips:

Use an adapter

Install the adapter in place of your existing speaker using brackets. Make sure your car’s speaker has enough room to sit correctly. 

Please check this video for step-by-step instructions:

Use spacing rings

The rings can help secure the device in place, but you have to install brackets to hold the rings tightly. 


Car speakers are available in different sizes. If you want to choose the perfect match for your vehicle, take some measurements carefully and correctly.
