I’m really impressed with this Znclces 2025 Upgraded 10" 1200W Slim Under Seat Powered Car Subwoofer. The slim design makes it much easier to fit in a car or truck without taking up a lot of space, and it still delivers surprisingly strong bass for such a compact unit.

These had good reviews on You Tube and on shopping sites. I ordered one and installed it in a car I am restoring. It was used maybe a couple hour each day for less than 2 weeks when the led quit working and a couple of days later the whole unit failed. I contacted Amazon and a replacement was sent and I returned the original unit. I did not have time to work on the car so the new unit did not get installed immediately. When I did have time to install it I found the replacement to be DOA. Talked with Amazon and they said they would have the company techs contact me as it was past their 30 day warranty. The company never did get back with me. Now I am stuck with a DOA unit that is useless to me. Amazon did their part, but from my perspective this company and their products are pretty much useless. FYI I did live sound for 14 years so I know electronics pretty well. My advice spend an extra $125.00 and get something from a company that produces good gear and stands behind it's products.

My son wanted speakers /sub for his 2015 Kia Soul , he didn’t want a regular speaker box because he needs the trunk space to transport his Tuba during the school marching band activities . I didn’t know that “under seat built in amp sub “ was a thing . After researching and reading some reviews , I decided to get this one . It came with everything that you need to complete the installation . Installation was pretty straightforward. Although it came with instructions, I decided to just look for installation videos online. Installed it under the driver seat and sounds GREAT !!! Perfect size and surprisingly loud for such a small setup . Well constructed and seems durable , and the LED add a nice touch , even when installed under the seat , it looks awesome as you can see the blue glow from under. As other mentioned , this setup won’t blow your car windows , but is powerful enough to enhance the sound and add some boom ! For the price , it was more than I was expecting . As far as durability , only time will tell (I will update if necessary ) but judging by the quality and the feel of it , looks like it will last . If you’re looking for an inexpensive way to enhance your current sound and have a small car or simply don’t want to have a huge speaker box in the trunk , I recommend this one .

I installed this amp/sub today and it definitely is an upgrade to a factory system. It pushes some decent wattage and costs a bit less than an entire setup. So here's the run down on how this thing works. It comes with 3 major cords a red, black, and yellow The red goes to your battery and you should have the fuse close to your battery. The darker colored short thick wire is your ground that you will typically attach to a bolt holding down one of the seats in the car/truck. ( you may need to strip off paint from the bolt for a better connection the yellow wire (should be freaking blue but I digress) is your remote wire. this will attach to the blue input on your stereo and controls the power on and off of the amp. you will see a raised input on the amp with 3 screws this is for the 12v red cord at the top , the remote yellow cord in the middle, and the dark grey ground cord at the bottom. I would used my own connectors for the wires because the ones that came with the amp are very flimsy and do not look like they could stand up for very long. RCA cables for left and right audio channels (run RR and RL to this not the SUB outputs) you will also receive a channel converter. this is for your stock stereo and you will run the RCA cables into this box then use speaker outputs to attach to the speaker wires of the similar colors Finally there is a speaker output set of wires that can tie directly into the speaker wires of your car that typically run along the paneling as you would a normal AMP. I'm fairly simple I just used the RCA to RR and RL on my after market stereo and they sound fine to me. As for the quality there: is very little heat generated or noise. the sub control knob is a great addition and easy to use. I have not adjusted the gains much on the amp just yet they are still set to low, but it puts out some decent sound for my normal settings if you don't know how this works you adjust the gain with your volume controls to set a sound balance. I only give this thing 4 stars because like other reviews the instructions are near non existent outside of don't use RCA and high end output. It does fit under the seat of a car fairly well. I drive an 8th generation Civic and it fits snugly under the drivers seat and I can adjust the seat with no issues. I have not driven long distance with it yet so I will update this should I notice any extra heat or issues. Hope this helps

I’ve been looking for a way to upgrade my car’s sound system without sacrificing trunk space or going through a complicated install process. This 9.5” slim under seat powered subwoofer checked all the boxes—and then some. I was honestly skeptical at first because of its size, but once I got it installed and tuned, I was completely blown away by the performance. Right out of the box, the build quality impressed me. It feels solid and well-made, with a sleek, low-profile design that tucks perfectly under the driver’s seat. Installation was straightforward—even if you’re not an audio pro, the included wiring kit and clear instructions make it easy to get everything up and running. Sound-wise, this little beast punches way above its weight. The bass is tight, deep, and surprisingly powerful for such a slim form factor. It adds a whole new level of depth to music that my factory system was seriously lacking. Whether I’m listening to hip-hop, rock, or electronic, the sub responds beautifully without overwhelming the rest of the audio. The 1200W peak power gives it plenty of kick, and the adjustable gain, bass boost, and crossover controls let me fine-tune the sound exactly how I like it. I love that I can enjoy solid low-end frequencies without the hassle of a huge sub box taking up my cargo space or rattling everything in the trunk. If you want a discreet but seriously impactful audio upgrade, this under seat subwoofer is a no-brainer. It’s perfect for anyone who wants to enhance their music without going all-in on a full custom system. Great value, great performance, and a total game-changer for my daily drive. Highly recommend!

Size of sub is not a 10” in a 10” box. A decent fit under my car seat. Sound is not too bad could be better. Value for your money not really because the wire kit they give you is a joke. 8g wire 🤣🤣🤣🤣 more like speaker wire. RCA cables are cheap and garbage, I had to extract the male part of the plug from the amp because it broke off in the port. It’s pretty light for a built in amp n sub. I’d have to say overall quality is not too bad I’m sure you can find a better setup for the price. I’m def going to be looking for a better one with better bass and build quality.

This is a great little amp that fit perfectly under my seat without any hassle. My buddy handled the wiring, and the installation went smoothly. Once everything was connected, I noticed a big difference. The sound now has much more depth and clarity. The build quality feels solid and durable, made from heavy-duty materials. It doesn’t overheat or rattle, even after long drives. Overall, it’s a compact, powerful amp that’s absolutely worth the money.
