We’ve reviewed more than our fair share of car speakers as of late. Aftermarket speakers are very popular for people looking for either a replacement or an upgrade. One of the most common questions we’ve been receiving about them is with regards to their measurement.
Curious about this question, we asked Nick, who has been a car stereo enthusiast for the longest time. If there’s a person who knows the answer, that would be him. He gave us the lowdown on how to measure car speakers, and we’ve put it together into a simple guide for you guys.
While there are multiple factors to consider when updating your car’s sound system, the size of your speakers should be one of your biggest concerns. Not picking up speakers of the right size is problematic for many reasons. The speakers with the wrong measurement will not fit into the dimensions of your car, which would then make modifications necessary. Also, not all cars have the same speaker setup. Therefore, a set of speakers that fits in Car A may not fit with Car B, and vice versa. As such, it is vital that you pick up correctly sized speakers to make your life infinitely easier.
The problem is that speaker manufacturers do not follow a specific system for measuring their speakers. Furthermore, the given measurements of a speaker don’t really correspond to the speaker size itself. This is what most speaker buyers don’t recognize, and it gives them major headaches come installation time. There are multiple measurements taken in speakers, and each one will greatly help you in finding a speaker that fits flush in the specific area where they will be used.

As mentioned earlier, the biggest problem facing buyers is the fact that no standardized means for measuring speakers exist. As such, learning how to measure car speakers is considered as something of a vital skill. Learning these measurements is perhaps your best bet to avoid purchasing ill-fitting speakers for your car. Nick shared some additional tips you can use to ensure that you get a set of speakers that fit.
Consider modifying your speaker mounts- In some cases, accurate measurements for stock speakers are not available for specific car models. Also, there are some cases where stock housing measurements do not correspond with any available aftermarket speakers. In these situations, the only available option is to modify the speaker housing. Some modifications can be as simple as converting the speaker’s mounting frame to match that of the car’s. Other modifications will constitute altering the housing itself, changing parameters such as housing depth and diameter.
Our resident car stereo enthusiast also says that your considerations should go beyond simply making the speakers fit in their respective places (though of course, that is still crucial). You should also consider wattage; the wattage of your speakers and head unit/amplifier should match for optimal performance. You should also check out other performance parameters such as frequency response. Integrated speakers should also be a part of your consideration if you’re looking for fuller sound in minimal space.
Knowing how to measure car speakers is an essential skill if you’re looking for aftermarket car speakers. Whether you are looking for a set that matches your stock sound system or you’re looking for an upgrade, it is important that you get speakers that fit. Getting the speaker measurements right is your ticket to getting it done.
