KICKER 51HS12 Hideaway 12 Inch Powered Subwoofer for Deep Bass

Description

The KICKER 51HS12 Hideaway HS12 is a compact powered 12-inch subwoofer system designed for drivers who want deeper bass without giving up valuable cabin or cargo space. Built with a low-profile, all-aluminum enclosure, it measures about 17-1/8 inches long, 12-1/8 inches wide, and 3-1/2 inches tall, making it a practical fit for many under-seat and other tight mounting locations. At approximately 17.5 pounds, it offers a space-conscious way to strengthen the low end in vehicles where a full-size subwoofer enclosure would be difficult to accommodate.

At the core of the HS12 is a built-in 230-watt RMS amplifier driving a 12-inch woofer. Its stated frequency response of 25–120 Hz supports the low-frequency range that factory speakers often cannot reproduce with enough depth or control. Rather than simply adding more volume, the system is designed to improve bass definition and balance. Adjustable controls help tailor the output to the acoustics of the vehicle, including a low-pass crossover from 50 to 120 Hz, a 25 Hz high-pass filter, a 0°/180° phase switch, and variable KickEQ with up to 6 dB of boost at 40 Hz.

Integration is another key strength of the KICKER Hideaway HS12. Its KICKER FIT+ technology is intended to simplify installation with a wide variety of factory and aftermarket audio systems. The unit accepts input signals from 0.25V to 40V, supports high-level speaker inputs, and can work with systems rated up to 400 watts at 4 ohms. Low-level RCA inputs are also included, giving installers flexibility across different vehicle audio configurations. This makes the HS12 especially useful in newer vehicles, including many equipped with start/stop systems, where traditional integration can be more complicated.

For day-to-day use, the included wired remote level control allows bass adjustment from the front seat without changing the main radio volume. The supplied multi-length wiring harness includes power, ground, speaker-level input, and remote turn-on leads to support installation in a range of applications. For systems that need more output, two HS12 units can be paired together with compatible KICKER remote solutions.

Before installation, it is worth checking mounting space, wiring needs, and the vehicle’s audio setup. For listeners exploring compact powered subwoofers, the KICKER 51HS12 Hideaway HS12 offers a thoughtful balance of size, flexibility, and controlled low-frequency performance.
