KICKER 51HS12 Hideaway Compact Powered Subwoofer, 12-Inch

Compact Powered 12-Inch Subwoofer System – Low-profile, all-aluminum 12" powered enclosure designed to fit under seats and in tight spaces while delivering strong low-frequency impact.

FIT+ Integration for Modern Vehicles – KICKER FIT+ (Fail-safe Integration Technology PLUS) accepts input signals from 0.25V to 40V (up to 400W at 4Ω) and is compatible with many newer start/stop vehicles without requiring an external line output converter.

230 Watts RMS with Full Control – Built-in 230-watt RMS amplifier with a 12 dB/octave low-pass crossover adjustable from 50–120 Hz, a 24 dB/octave high-pass filter at 25 Hz, 0°/180° phase switch, and variable KickEQ bass boost up to +6 dB at 40 Hz.

Included Remote Bass Level Control – Wired remote knob lets you adjust subwoofer level from the driver’s seat without changing the main radio volume, so you can dial in the right amount of bass for any song or volume setting.

Broad Frequency Response in a Slim Enclosure – Plays from 25–120 Hz in a compact chassis measuring approximately 17-1/8" (D) x 12-1/8" (W) x 3-1/2" (H) and weighing about 17.5 lbs (7.92 kg), making it suitable for a wide range of vehicles and seating locations.

The KICKER 51HS12 Hideaway HS12 is a compact powered 12-inch subwoofer system designed to deliver serious low-frequency impact from a low-profile, all-aluminum enclosure. Built to fit under many seats and in tight spaces, it adds deep, controlled bass without sacrificing cargo or cabin room. With KICKER’s FIT+ (Fail-safe Integration Technology PLUS), the HS12 accepts input signals from 0.25V up to 40V (400 watts at 4 ohms), making it compatible with a wide range of factory and aftermarket head units, including newer start/stop vehicles. Whether you connect via low-level RCA or high-level speaker inputs, the HS12 is engineered to integrate cleanly into modern vehicles without needing an external line output converter. The onboard 230-watt RMS amplifier is paired with a 12-inch driver and a fully adjustable control set, including a 12 dB/octave low-pass crossover (50–120 Hz), 24 dB/octave high-pass filter at 25 Hz, variable KickEQ bass boost up to +6 dB at 40 Hz, and a 0°/180° phase switch. An included wired remote level control lets you fine-tune bass output from the driver’s seat, independent of the main radio volume. For systems that demand even more low-end impact, you can run two HS12 units and manage them together with compatible KICKER remote solutions. Despite its slim profile—just 3-1/2 inches tall with a 17-1/8 x 12-1/8 inch footprint—the HS12 delivers a broad 25–120 Hz frequency response and surprising output for its size. A multi-length wiring harness is included (power, speaker-level input, ground, and remote turn-on leads) to streamline installation in a variety of vehicles.
