Description
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.

Incredible, crisp, bass from small size.
I have no idea how something so compact can create such clear, thumping bass! This gave me the exact amount of bass I was looking for. Hits hard and crisp. Rattles my rear view mirror without out impacting side mirrors much. This won't shake your neighbors windows as you drive by obviously, but for a compact, all inclusive, less than 20amp draw you won't find better. It fits completely hidden behind back seat in my f150 with 0 modifications. Worth the price all day!

You'll be impressed
This thing bumps. I got the 12 inch. Thoroughly impressed for its size. I have a corvette c8 eray very limited space to add bass. Original plan was to buy one. Then add a second its worth it. Truthfully no need. Very happy with the added bass. Pretty easy install in my drive way.

Veteran basshead approved
First and foremost, this isn’t two 12s in a ported enclosure on 5,000 watts. It’s two shallow 12s in a tiny sealed enclosure on 200 watts each (in my case at least). So don’t expect your windshield to flex. But for the footprint, I am blown away. Every car is different, but this one is installed in a tiny Porsche boxster behind the seats, and even so, it’s rocking the mirrors. The sound is primarily punchy, but it’s full and useable. Ideal bandwidth id say ranges between 35hz to 100hz which is decent for everyday music. But it does lack below 35hz, but it’s to be expected for the footprint. I’d say the performance is comparable with the price and I am very satisfied. This is coming from someone who has an armada with 4 18s in a 6th order wall on two salt 8ks.

Perfect for Wrangler JL
While I think it’s slightly overpriced, the convenience of having nearly all you need included is a plus. It’s an absolute perfect fit for the rear cargo tub in a Jeep Wrangler JL, keeping it discrete. Because it’s so far away from the other speakers, the phase needs to be set to 180. Sounds amazing!

Do not buy Kicker 12 Inch Hideaway Technology Leveled Up
I can testify I brought two. They sound great. I had them professionally installed by a reputable installer. They both have clonked out and I wasn’t in the best of health when I purchased them. I mean that I brought them to knowing I had 30 days to return them or purchase the two year warranty for 2 years from asurion. I was sick and my truck was in the shop so I forgot to purchase the warranty. I purchased them on July 10th 2026 and I had them installed July 11th so I used and enjoyed them until July 15TH. So not until August 10th 2026 I really didn’t use them from July 15TH 2026. On August 18th one died on me. I called kicker and they had me sent it back because it was warranty. That cost me around 80 dollars for the box and ups ground shipping to send the speaker back to kicker. Now last night August 28th I was one of the two I had installed in my Acura 2020 MDX. One because the other was sent back to kicker for repair unfortunately. Now last night I was tailgating playing diverse hip hop and rnb music and I had my bass knob half way and my radio set to 34 out of 40 and the second speaker died. I’m so disappointed at kicker. I’m embarrassed. I was on a date and I was the party. Just out of know where the bass disappeared. So now another unspecified time and another 80 dollars I’m going to be out of for me to ship back to kicker. Also I don’t know when I will be able to have bass. I’m going on a road trip Monday and I looked forward to the 12 hour road trip. Now here I am out 478 dollars times 2 plus 80 times two for me to send back to kicker. I didn’t even have a whole 30 days of playing music before both the speakers died. I am very disappointed and embarrassed plus sick to my stomach literally. I will never recommend these speakers to anyone. Don’t do it. They sound awesome but they don’t make them durable for hip hop and rnb music.

Blown Away By the 51HS12
This has exceeded my expectations and I will definitely buy more from Kicker in the future / great BANG for your buck. Spliced into the front door speakers of my 2016 Crew Cab F150 - it really fills the cabin with bass. Kicker support team is outstanding they have made life long customer out of me strictly on this alone . Kelton at Kicker is a great resource and helped me throughout the installation process.

It's OK
I replaced my stock Bose subwoofer with this unit in my 4M Audi Q7. The stock Bose sub has a massive ported box that lives under the rear deck. I simplified the layout and put in a power inverter alongside this sub. If tuned perfectly it delivers a punch. It could be my Bose, but I have hours into tuning this thing and it's either overwhelming (not in a good way) or not much better than my stock Bose sub. I gave it 3 stars because it's small and mighty, but I regret not going with a custom box for my limited space.

Nice speaker, big sound
Everything i wanted the hideaway 10 to be. Its good, doesn't compare to a real setup. That said it absolutely brings the third dimension of music to life. For running alpine off the deck with this in the back, its balanced. Easy to install
