Speaker Sizing For Your Car: Australia Edition

what size speakers fit my car australia

When it comes to car speakers, finding the right fit for your vehicle can be confusing. While it's important to measure the space where your existing speakers sit, the process is a little more complex than simply matching those dimensions. This is because car speaker sizes are categorised based on the diagonal distance between frame mounting holes, rather than the actual outside diameter of the basket. To ensure the right fit, it's recommended to search for the make, model, and year of your car in an online database, and then measure the space yourself for maximum accuracy.

Speaker size vs. basket size

When it comes to car speakers, it's important to understand that "speaker size" typically refers to the diagonal distance between frame mounting holes, rather than the actual outside diameter of the basket that fits into the door opening. This distinction is crucial because it determines the maximum speaker cone size that will fit into your car's door opening.

To ensure you get the right speaker size for your car, it's recommended to consider the following:

The speaker size category, such as "6-1/2 inches," doesn't always reflect the exact diameter of the speaker. Instead, it serves as a general categorisation, and the actual dimensions can vary depending on the manufacturer's design. Therefore, it's important to focus on the basket size, which is the part that fits into the door opening.

When choosing speakers, it's essential to measure the door opening in your car, as this will determine the maximum basket size that will fit. For example, if your car's door opening is 6.1 inches, you can install a speaker with a basket size of just under 6 inches, allowing for the maximum speaker cone size.

Online Databases and Measurements

To find the right speakers for your car, you can utilise online databases that provide information on compatible speaker sizes for specific car makes, models, and years. These databases take into account various measurements, including the speaker frame size, hole alignment, and other dimensions, to ensure the best fit.

Additionally, it's worth noting that factory speakers may not adhere to standard size measurements, as they are designed specifically for the vehicle. Therefore, measuring each location, such as the door speakers and rear speakers, is crucial to ensure the correct speaker size.

Single vs. Double DIN Stereos

When considering the head unit or stereo system in your car, the most common size is Single DIN, with dimensions of 50mm x 180mm. Double DIN stereos, on the other hand, measure 180mm x 100mm and are often found in luxury vehicles, providing space for additional features like reverse cameras and navigation systems.

By taking accurate measurements, utilising online resources, and considering the specific characteristics of your vehicle, you can ensure that you choose the right speaker and stereo setup for your car in Australia.

Single vs. double DIN stereos

DIN is an acronym for "Deutsches Institut für Normung", the German Institute for Standardisation. This German institute created the standard measurements for car radios and related car audio equipment. Single DIN and double DIN are the two standard sizes for car stereos. A single DIN stereo measures 2 inches (50 mm) in height and 7 inches (180 mm) in width, while a double DIN stereo measures 4 inches (100 mm) in height and 7 inches (180 mm) in width.

Single DIN stereos are generally more affordable, compact, and easier to install compared to double DIN stereos. They offer basic functionalities, such as AM/FM radio, AUX input, Bluetooth audio connection, and in some cases, CD players, Bluetooth calling, and digital radio. Single DIN stereos with touchscreens are also available, providing similar functionality to double DIN units, even when installed in a single DIN slot.

Double DIN stereos offer larger screens, better functionality, and modern technology integration. They often feature touchscreens, Bluetooth connectivity, GPS navigation, reversing camera functionality, multimedia playback, and phone integration. Premium double DIN stereos may include apps like Android Auto and Apple CarPlay, allowing for a seamless integration of your smartphone. Additionally, double DIN stereos enable video watching and mobile gaming when paired with Android Auto. However, it's important to note that these apps should not be used while driving as they can be distracting.

When choosing between a single DIN and a double DIN stereo, consider your car's dashboard size and your feature preferences. If you prioritize compactness and ease of installation, a single DIN stereo might be the better option. On the other hand, if you want a larger screen and more advanced features, a double DIN stereo would be more suitable. Keep in mind that installation kits and wiring adaptors are typically required when upgrading to a double DIN stereo.

To ensure compatibility and a seamless fit, it is recommended to search for your car's make, model, and year in an online database to determine the compatible stereo sizes and any necessary installation considerations. Measuring the head unit space in your car's dashboard can also help confirm the required stereo size.

Measuring the head unit

To measure the head unit size, first remove the current car's head unit. Then, use a tape measure or a ruler to measure the space where the existing head unit sits. You may need to remove some of the trim around the head unit to get an accurate measurement. Based on the size of the opening, you can determine what size head units will fit in your car.

Single DIN is the most common size for car stereos, with dimensions of 50mm x 180mm. If your head unit is 4" tall, a double DIN head unit will be a direct-fit replacement. If your head unit is 3" tall, you can replace it with a 1.5 DIN head unit or a single DIN unit with the appropriate kit. For a 2" tall head unit, you will need to replace it with a single DIN head unit, unless your vehicle has a "spacer" or "pocket" that provides enough space for a larger unit. A double DIN stereo space measures 180mm x 100mm and is a feature of many luxury vehicles, accommodating features like reverse cameras and navigation systems.

You can also search for the make, model, and year of your car in an online database to find compatible head units. It is recommended to do both this and physically measuring the head unit to maximise accuracy.

Online databases

When it comes to finding the right size speakers for your car in Australia, there are a few online databases you can refer to. These databases can help you determine the correct speaker size and type for your specific vehicle. Here are some details on using online databases for this purpose:

One option for finding the right size speakers for your car is to use an online database that provides information about car audio gear compatibility. Websites like Crutchfield offer a massive fit database that can help you find the right speakers for your vehicle. To use these databases, you will need to know the make, model, and year of your car. By entering this information, you will be able to access a list of compatible speakers, along with installation instructions and any necessary adapters.

Crutchfield, in particular, has spent decades researching car audio equipment. They have disassembled tens of thousands of vehicles and measured the spaces where factory speakers fit. Their database compares these measurements with the dimensions of different speakers to determine compatibility. This ensures that you will find speakers that satisfy the depth, diameter, and height requirements of your vehicle's speaker openings.

Speaker Size Considerations

It is important to note that car speaker sizes are categorised based on the diagonal distance between frame mounting holes, rather than the actual outside diameter of the speaker basket. This means that a 6.5-inch speaker, for example, may not have a 6.5-inch diameter in reality. Therefore, it is always a good idea to measure the space in your car and compare it to the measurements provided in the database to ensure an accurate fit.

Single vs. Double DIN Head Units

When choosing a new head unit for your car stereo, you will also need to consider whether your vehicle is compatible with single or double DIN head units. A single DIN stereo, such as the Alpine ILX-F509A Halo9, is the most common size and does not require special adapters. A double DIN stereo, on the other hand, offers additional space for features like reverse cameras and navigation systems. Measuring the space in your car will help you determine which type of head unit is suitable.

Custom Fit Options

Some websites, like Sound Garage, offer custom fit services. By entering your vehicle's make and model, you can find a car stereo that perfectly matches your car's specifications. This ensures that you purchase a head unit that fits seamlessly into your car without any installation issues.

In conclusion, online databases can be a valuable resource for determining the right size speakers for your car in Australia. By providing information about your vehicle and utilising measurement tools, you can find compatible speakers and head units that offer a perfect fit and an enhanced audio experience. Remember to consider the unique characteristics of car speaker sizing and the availability of custom fit options to make the most of these online resources.

Speaker frame and hole alignment

When it comes to fitting speakers in your car, it is important to note that car speaker sizes are categorised based on the diagonal distance between frame mounting holes, rather than the actual outside diameter of the basket. This means that a car with a 6.5" speaker specification and a 6.1" door opening can install a speaker with a basket outer diameter of just under 6".

To ensure the correct fit, it is crucial to consider not only the diameter of the speaker's cone or the cutout diameter but also the size of the speaker frame and hole alignment. The size designation is closely related to the frame's diagonal measurement. For example, a 6-1/2" speaker's hole pattern is different from that of a 6-3/4" speaker.

When installing aftermarket speakers, it is important to check the depth of the speaker as well as the diameter. Aftermarket speakers often have larger magnets than standard items, which may be too large to fit in the standard location. In the case of door speakers, it is important to ensure that the window can still slide open without obstruction.

To avoid drilling holes in your car, vehicle-specific speaker adaptors can be used. These adaptors mimic the shapes and sizes of standard speakers, ensuring optimum fitment. Speaker adaptors are available for most core cars and can include wiring adaptors for easy installation.

Additionally, it is worth noting that the size of the factory speaker in your vehicle may not always adhere to the same size standards as aftermarket speakers, as they are designed to work with the overall design of the vehicle. Therefore, it is recommended to measure the space and consult online databases or audio professionals to determine the correct speaker size and fit for your car.
