The 7 Best Underseat Powered Subwoofers for Your Car (2022) (2023)

Most cars don't have a lot of extra space that can be used to place subwoofers. But just because there's no space doesn't mean you have to sacrifice the quality of music in your car. Go out and get an underseat subwoofer.

An underseat subwoofer is a small subwoofer that features a built-in amplifier in a compact enclosure. This clever design is perfect when it comes to installing a subwoofer for your vehicle, eliminating the need to get a woofer, couple it to a separate amplifier, and then wire it up as best you can.

The best place to install a small powered subwoofer would be under the driver or passenger seat, behind the back seat, or in the back seat. This depends on your car type.

Finding the perfect underseat subwoofer for your car can be a daunting task given the many models available on the market today. But no worry; I understand you. Below is a list of 7 of the best underseat subwoofers you can't go wrong with.
