The Rockville RG212CA is a loaded, vented enclosure with two 12-inch subwoofers and a built-in amplifier, rated at 2000 watts peak. It is designed to add serious low-end output to a car audio system without taking up a full trunk, thanks to its slim profile. It includes a remote bass knob, adjustable low-pass crossover, and both RCA and high-level inputs for easy integration with most receivers. It suits shoppers who want maximum bass for the money and have the space for a wide enclosure, but it is not a precision sound-quality sub and needs careful gain setting to avoid distortion.

Slim Design, Big Performance Despite its powerful output, the RG212CA v2 takes up minimal space in your trunk. The slim design accommodates two 12” subwoofers in a vented enclosure, while the amplifier is fine-tuned for maximum performance. At only 6” longer than the single 12” version, this model delivers double the bass while still saving trunk space. Powerful Sound This subwoofer is designed for those seeking a louder, more impactful audio experience. The vented enclosure and higher-powered amplifier combine to produce deep bass that can shake mirrors and be heard from two blocks away. A built-in limiter circuit helps eliminate distortion at peak volume levels, ensuring clean, powerful sound. Flexible Inputs for Easy Installation The RG212CA v2 offers both RCA and high-level inputs, making it compatible with a wide range of receivers. Whether your receiver has RCA outputs or not, installation is quick and straightforward. The power, signal, and remote turn-on terminals are angled for easy connection and disconnection. Remote Bass Control The included remote bass knob can be mounted on your dashboard, allowing you to easily adjust the subwoofer’s volume from the driver’s seat. Adjustable Low-Pass Crossover The adjustable low-pass crossover lets you filter out unwanted frequencies, optimizing the performance of your subwoofer. You can set the crossover to ensure that the subwoofer plays only the desired low frequencies, based on your full-range speakers' settings. This subwoofer offers a complete solution for adding powerful bass to your car audio system.
