Kicker 51HS12 Hideaway 12" Compact Powered Subwoofer - Each

The Kicker 51HS12 is built for drivers who want deep, powerful bass without giving up precious space. This 12-inch powered Hideaway subwoofer packs serious low-end punch into a compact, under-seat design. Small footprint, big attitude—that’s the idea.

Compact Size, Serious Impact

Don’t let the size fool you. The Kicker 51HS12 Hideaway 12" Powered Sealed Subwoofer delivers impressive low-frequency impact from a tough, all-aluminum frame. It’s a fully loaded enclosure with a 12-inch woofer, giving you more depth and output compared to smaller 8-inch or 10-inch options.

And here’s the kicker—it still fits neatly under your seat. With dimensions of just 17-1/8" deep, 12-1/8" wide, and 3-1/2" high, this loaded box is designed to blend into your vehicle without taking over your cargo space. You get the muscle of a 12-inch sub without sacrificing room.

Built-In Power That Delivers

The Kicker 51HS12 features a built-in amplifier rated at 230 watts RMS, falling within the 151W–300W power range. That means you’re getting consistent, clean power tailored specifically to this sealed enclosure.

The frequency response of 25Hz to 120Hz ensures you feel the lows while keeping everything tight and controlled. With a 12dB/octave low-pass crossover adjustable from 50–120Hz and a 24dB/octave high-pass at 25Hz, you’re in control of how your bass blends with the rest of your system.

FIT+™ Technology – Works with Almost Any Vehicle

The Kicker 51HS12 comes equipped with FIT+™ (Fail-safe Integration Technology PLUS). It accepts input signals from as low as 0.25 volts all the way up to 40 volts (400 watts at 4Ω).

What does that mean for you? It works with almost any vehicle on the road today—even newer models with start/stop systems. No added expense of a line output converter. Low-level input sensitivity ranges from 250mV–10V, and high-level input handles 1V–40V. Flexible and ready for modern systems.

Rockin’ Remote Control

The included remote bass control lets you tweak your bass without touching the main volume. Turn the knob to increase or decrease bass output independently from your radio volume.

If you’re running two mono amps or powered subwoofers, you can use the KICKER DBRC Dual-Amp Bass Remote to manage both from a single knob. It’s like having a bass command center right at your fingertips.

Fully Loaded with Smart Features

The Kicker 51HS12 includes:

• Variable KickEQ boost up to +6dB at 40Hz
• Adjustable low-pass crossover
• Phase switch (0°/180°)
• Two auto turn-on options: DC-offset or signal sensing

These features let you fine-tune your sound so it hits just right. Whether you want subtle depth or chest-thumping impact, this sub adapts to your taste.

Sealed Enclosure for Tight, Accurate Bass

This sealed enclosure design ensures tighter, more accurate bass response. Instead of boomy or loose lows, you get controlled, punchy performance that complements your music. The Kicker 51HS12 delivers a clean low-end foundation that makes every track feel fuller and more alive.

Double the Bass, Double the Fun

Run two HS12 units and control them together with the KICKER DBRC Remote for even more output, presence, and impact.
