Car Subwoofers

Transform your car’s sound with our range of aftermarket car subwoofers. Engineered for powerful, precise bass and seamless system integration, we've chosen the very best products on the market to ensure you take your car audio to the next level. Whether you’re enhancing an existing setup or upgrading from factory audio, our selection delivers performance, reliability, and the perfect fit for your vehicle.

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 alone simply can’t reproduce.


Whether you're looking for subtle low-end warmth or powerful, hard-hitting bass, an aftermarket subwoofer transforms your in-car listening experience and adds new depth, clarity, and impact to every track.

Solutions for Every Type of Installation

Our subwoofer range covers every application, from compact under-seat units that preserve cabin space, to high-power enclosures designed for maximum output.


Whether you’re upgrading a factory system, building a custom install, or fitting for a customer, you’ll find trusted brands, clear specifications, and reliable performance across the range.


From plug-and-play powered enclosures to high-performance component subwoofers featuring advanced cone materials and cutting-edge design, we offer solutions for every vehicle and budget. You’ll also find OEM-style and discreet options that integrate seamlessly into your vehicle without compromising sound quality.

Choosing the Right Subwoofer for Your Car

See below for some tips on how to choose an aftermarket subwoofer, and be sure to use our vehicle compatibility checker to help you find the right product!

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

Subwoofer Size & Output

Subwoofer size plays a major role in how your system sounds:

  • 8"–10" subwoofers – Tight, controlled bass; ideal for smaller vehicles or subtle upgrades
  • 12" subwoofers – A versatile all-rounder with strong, deep bass
  • 15" subwoofers – Maximum output and low-frequency impact

Tip: If you want balanced performance, a 10" or 12" is the best choice for most vehicles.

Enclosure Type Explained

The enclosure has a huge influence on sound quality and output:

  • Sealed enclosures – Precise, accurate bass; great for all music types
  • Ported enclosures – Louder, deeper bass with more impact
  • Under-seat subwoofers – Compact, space-saving and easy to install

Tip: Limited on space? Under-seat or compact enclosures are ideal.

Power Handling & Amplifier Matching

For the best performance, your subwoofer and amplifier need to work together:

  • Focus on RMS power ratings, not peak power
  • Match your amplifier output to your subwoofer’s RMS rating
  • Check impedance (ohms) for compatibility

Tip: Proper matching ensures clean, distortion-free bass and protects your equipment.

Matching Your Subwoofer to Your Vehicle

Different vehicles require different setups:

  • Small cars – Compact or under-seat subwoofers
  • Hatchbacks – Flexible space for enclosed systems
  • Saloons – May require more power for bass to carry into the cabin
  • SUVs & vans – Ideal for larger, high-output setups

Installation & Accessories

To get the most from your subwoofer, consider:

  • Amplifiers
  • Wiring kits
  • Sound deadening
  • Vehicle-specific fitting accessories

Tip: Using the right accessories ensures better performance and a cleaner installation.

What is the difference between sealed and ported subwoofer enclosures?

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.
