What is an 8 inch subwoofer?
An 8 inch subwoofer is a compact speaker designed to handle low-frequency sound, like basslines and kick drums, with greater depth and clarity than standard speakers. While smaller than other sub sizes, 8 inch subs deliver surprisingly powerful bass that’s tight and responsive. These are perfect for drivers who want to improve sound quality without installing a bulky or overly aggressive system. These subs are often used in sealed or compact enclosures, making it a great solution for hidden installs or under-seat mounting.
How to choose an 8 inch subwoofer
When choosing an 8 inch sub, consider how much space you have and what kind of bass you prefer. Look at specs like RMS power handling, sensitivity, and enclosure type, whether it's sealed for tight response or ported for more volume. Also check the sub’s impedance and voice coil configuration to ensure it matches your amplifier. Some models are powered (with a built-in amp), while others are passive and require a separate amplifier. At Supercheap Auto, our team can help you match the right sub to your system and get the most out of your upgrade.
Compact bass upgrade for any vehicle
8 inch subwoofers are perfect for everyday drivers who want a noticeable boost in bass without a massive audio overhaul. These are ideal for hatchbacks, sedans, utes and even dual-cab 4WDs, where space can be limited but sound still matters. These are easy to integrate into your existing setup and work well when paired with a dedicated amp. If you're after better balance, cleaner sound, and more punch from your playlist, an 8 inch sub is a great place to start.

Frequently Asked Questions - 8 Inch Subwoofers
Are 8 inch subwoofers any good?
Yes, 8 inch subwoofers are great for adding clear, punchy bass without overwhelming your system. These are ideal for smaller vehicles or for anyone looking to upgrade their sound without sacrificing boot space or volume balance. While these don’t deliver the extreme low-end rumble of larger subs, these offer tighter, more responsive bass that blends well with factory or upgraded speakers.
How big is an 8 inch subwoofer?
An 8 inch subwoofer refers to the diameter of the speaker cone itself, which is roughly 20cm across. However, the total size of the sub – including the frame, magnet, and enclosure – can be larger. Depending on the design, a typical 8 inch subwoofer box or powered unit may require anywhere from 10 to 15 inches (25-38cm) of mounting space. Some models are built slim for under-seat or tight-space installations, making it easy to fit in most vehicles.
What is the difference between an 8 inch subwoofer and a 10 inch subwoofer?
The main difference between an 8 inch and 10 inch subwoofer is bass output and space requirements. A 10 inch sub generally delivers deeper, louder bass and is better suited for high-volume or bass-heavy music, but it needs more room and power. An 8 inch sub offers tighter, more responsive bass and is easier to fit in smaller spaces like under seats or in compact enclosures, ideal for balanced, everyday listening without overwhelming your audio system.
