Amplified Car Subwoofer Modules

Get powerful, plug-and-play bass without the complexity of a separate amplifier and enclosure with 12 Volt Outlet's selection of amplified car subwoofer modules — all-in-one units that combine a subwoofer, enclosure, and built-in amplifier into a single ready-to-install package.

Amplified subwoofer modules are the most convenient way to add real bass to any vehicle. Everything you need is built in — the subwoofer driver is already loaded into a tuned wood or plastic enclosure, and the amplifier is integrated directly into the box. Just wire to your head unit's RCA outputs or speaker-level inputs, run power and ground, and you have deep, impactful bass with minimal install time and no external components to source, match, or mount separately.

Available in compact underseat designs and larger trunk-mounted configurations, amplified subwoofer modules fit a wide range of vehicles and install locations. Many units include bass boost controls, remote bass level knobs, variable low-pass filters, and high-level speaker inputs for easy integration with factory radios and head units without preamp outputs — making them an ideal upgrade for stock systems and simple builds alike.

Whether you're adding bass to a daily driver, a second vehicle, or any build where simplicity and quick installation matter, an amplified subwoofer module delivers real results without the complexity of a full component system.

We carry amplified car subwoofer modules from the most respected brands in the industry including Rockford Fosgate, B2 Audio, Soundqubed, Orion, Massive Audio, Audio Ace, DC Audio, Resilient Sounds, AudioControl, Jensen, Nemesis, Powerbass, JBL, Infinity, and more — brands that build all-in-one bass solutions for real-world performance and everyday reliability.
