Transform Your Car's Sound

A high performance car subwoofer is the foundation of any serious audio upgrade. By handling low frequencies separately, subwoofers unlock deeper, richer bass that standard speakers simply can’t reproduce. From subtle, controlled low-end detail to full-scale bass impact, an aftermarket subwoofer gives your music the depth and clarity it deserves.

Whether you’re building a custom audio system, replacing a tired factory setup, or fitting for a customer, you’ll find trusted brands, clear specifications, and products that deliver consistent results. From pre-loaded, powered enclosures designed for easy installation to high-performance subs loaded with the latest technology and advanced con materials, we have something for everyone. You'll also find OEM-friendly options that blend dicreetly into your vehicle without compromising sound quality.

When selecting your aftermarket subwoofer, consider the balance between space, power, and performance:

Size & Enclosure – 8" and 10" subs offer tight response in small spaces, while 12" and 15" units deliver more depth and volume.

Power Handling & Amplifier Matching – Match RMS power ratings carefully for efficient, distortion-free performance.

Enclosure Type – Sealed boxes provide controlled, accurate bass; ported designs deliver greater volume and low-end extension.

Integration & Compatibility – Choose subs designed for your vehicle type or available mounting space for a clean, professional finish.

Installation & Accessories – Use matching wiring kits, amplifiers, and sound-deadening materials to get the most from your setup.

How do I choose the right subwoofer size for my vehicle?

Selecting the appropriate subwoofer size depends on your desired bass output and available space. Common sizes include 8", 10", 12", and 15". Larger subwoofers generally produce deeper bass but require more space. Use our compatibility tool to find subwoofers that fit your vehicle's specifications.

Do I need an amplifier for my subwoofer?

Yes, most subwoofers require an amplifier to achieve optimal performance. An amplifier provides the necessary power to drive the subwoofer effectively. We offer subwoofer and amplifier packages that are pre-matched for your convenience.

What is the difference between sealed and ported subwoofer enclosures?

Sealed Enclosures: Provide tight, accurate bass with better transient response.
Ported Enclosures: Deliver louder bass with more efficiency but may sacrifice some accuracy.

Your choice depends on your music preferences and desired sound characteristics.

Can I install a subwoofer myself?

Installation difficulty varies by vehicle and subwoofer type. Many of our enclosed subwoofers are designed for easy installation with minimal tools. However, if you're not comfortable with car audio installations, we recommend seeking professional assistance to ensure optimal performance and avoid potential damage.
