Rockville RWS12CA 12″ Slim Powered Car Subwoofer with Enclosure

The Rockville RWS12CA 1200W 12″ Amplified Powered Car Subwoofer Enclosure delivers hard-hitting bass in a slim, space-saving design. Perfect for cars, trucks, and SUVs, this all-in-one system combines a subwoofer, enclosure, and amplifier to simplify installation while maximizing sound quality.
With 1200 watts peak and 300 watts RMS, the ultra-stiff composite pulp cone with Kevlar reinforcement and 2″ high-temperature aluminum voice coil produce powerful, distortion-free bass. A vented core magnet motor structure, high power Strontium magnet, and 96dB SPL sensitivity deliver accurate response across a 38Hz–500Hz frequency range.
The slim enclosure (24″L x 15″H x 4.37″–6.65″D) fits neatly under seats or into tight trunk spaces, saving room without sacrificing performance. A built-in 300W RMS amplifier with adjustable low-pass crossover (50Hz–250Hz), +12dB bass boost, and RJ11 jack for a dash-mounted remote allows fine-tuned control.
High- and low-level inputs with Smart Turn-On circuitry make the RWS12CA compatible with factory and aftermarket systems. The sealed MDF enclosure is finished with aviation-grade carpet and a synthetic leather front for durability and style.
