Title: Budget No Brainer
Review: will fit almost anywhere. good build quality. even though it doesn’t meet it’s power ratings still provides a good amount of power in a very small package at the price of $46. included remote level control is nice.UPDATE: reconfigured the single 10″ 2 ohm DVC subwoofer this amp pushes from a series 4 ohm load to a 1 ohm parallel load, and this little budget gem really shines. no shutdowns and only mildly warm to the touch. if you want to take a chance and see what $46 can do go ahead and give it a try……at your own risk of course. but in this case it’s delivering around 500 good sounding watts into a single 10″ load at 1 ohm. will do a future update if anything changeIt truly will run 1 ohm just fine with no issues for me at all, and make plenty of clean power doing it for it’s size. they must rate it to only 2 ohms so as not to step on the toes of other brands who have them build virtually the same amp selling for higher cost. you can pretty much take it’s power ratings and shift them from 4 and 2 ohms, to 2 and 1 ohms and that is the real power you will be getting at 2 and 1 ohm loads.

Title: 3.5 stars works, but….
Review: 3.5 Stars.. powerful enough for the size, BUT as some others have stated, it requires a line driver to work. Other amps work great with the budget head unit it is paired with, but with this amp can barely hear the subwoofer without a line driver on it.

Title: Incredible for the money
Review: I have a mid-size crossover currently, had no sub from the factory. I’m a high end snob, I’m very much so into the clarity and accuracy of audio reproduction in the car-audio segment of things. I built a 1 1/4 cuft. box, slapped a nice woofer I had laying around into it, I set the gain and crossover with my D’Amore Engineering DD-1 and CC-1. I’m pushing this thing into a 2 ohm load, and let me tell you. With a good box, good woofer, good settings, and a good power supply, this thing absolutely slams. For reference, I had a similar setup with a Rockford Fosgate P300X1, which on a dyno makes around 300W burst into 2 ohms, this does the same for… a sixth the price? Now, that’s all fine and dandy, but how’s the audio quality? It’s great, it’s really great. I can’t believe how clean the output is for how cheap this thing is. There’s super low noise floor (noise that escapes the class D filtering and makes it to the output). It’s absolutely shocking for the price, I really can’t describe it any other way.I would appreciate the company producing this product, if they’d take this feedback, as these simple things would make this amplifier significantly better.1. Power inputs should be larger, 8 AWG. 10AWG basically doesn’t exist…2. Remove the high pass crossover, make it only have a low pass.3. Increase the jack size of the bass knob. The jack on the amplifier is smaller than on the bass knob.4. Increase internal fuse size, and change ratings to include 1 ohm testing. This amplifier works fine at 1 ohm, gives me and others no problems at 1 ohm, even with 35A fuse. It would be nice if it was equipped for it from the factory, and it meets its rated power at 1 ohm!Extra details too;The company that makes this amp, ALSO makes “AUDIOZERONE” and they have the “PLINIUS” brand trademarked as well as the other, in the US. So these will likely be their brands going forward. They are a China based company, which in this case is a good thing, as they are a manufacturing company selling directly to the consumer, this means that they are able to sell at a significantly lower price than everyone else.From an engineering perspective;Overall looks good. There are a plethora of low-ESR capacitors inside the amplifier. They’re of a cheaper brand, but this is alright in this case as it looks like for reliability purposes, they put way, way more than necessary. These also help reduce input and output noise.Notably though, the caps are rated to 50V, which means the power rail is likely running around 35-45V, which is very, very nice for an amp this small, as it helps it make a lot more power in a compact size. The power components are made by TSD semiconductor, a Beijing based company, very reputable for their quality too, which is a good indicator components were picked with the best ones where they matter.The output frequency filter is also of high quality, made by CODACA, it is a CPCF2919 model, high current type. Very, very good quality for the price, CODACA components are very good, usually not a known name due to them mostly being used for OEM applications.Thermals; Semiconductors are mounted to a common rail with thermal paste, this rail is then mounted to the case, lots of metal between the semiconductors and the atmosphere allows for more heat to be transferred directly into solid metal, this works well for high power applications. This is a low power, high efficiency application, the amplifier will literally never overheat unless you seal it in a thermally isolated box or an oven, or whatever equivalent you find out how to do in a car. What I’m trying to say is; you’re going to have to really mess up or try to overheat this thing, very thermally efficient. This also bodes well for longevity, as it means all components will run cooler, and electrolytic capacitors love running cooler.Overall, very well built, very good sound quality, shocking price. I hope to see more from this company at this price point, as it will severely disrupt the market and make every manufacturer become more competitive.

Title: Not ready for the big leagues
Review: Pros: Size and power efficiency by far are the best things about the amp. I didn’t have a lot of install room so I was hoping this would work well.Cons: Terrible Class-D EMI interference with my radio tuner (FM reception would drop every time the beat of the music would hit / Bluetooth was fine but some people do still use their radio tuners these days…Low and High Level inputs need way more gain…Auto Sensing of High Level Inputs was useless as they just powered the amp non-stop which would have killed the vehicle battery…The remote bass knob’s female input jack was intermittent / wiggle the back of the cord lightly and it would work for a moment.Huge waste of time.

Title: Great small amp
Review: AWESOME budget amp, not super powerful but at max settings it certainly does the job, especially for the size form and cost. Perfect for my application.

Title: Small, powerfull, accurate, good VFM. (Pay attention buyers who claim it bearly moves the subwoofer)
Review: At the begining i noticed its not powerfull and bearly moves the subwoofer. gain and volume are at maximum. tried High-level input and RCA inputs, both without any change. I even checked the output voltage of the Head-Unit with 40Hz track and 1KHZ track, output voltage was good.I contacted amazon CSC and the seller, and we agreed on returning the item.And then…To make along story short: Buyers who claim that its not powerfull and using the high level inputs or RCA inputs, do this: Use Pre-Amp line-driver OR active crossover OR Dsp. your Head-Unit output is weak (it can happend with the Stock head-unit of the car, and also with After-Market Headunits (Its rare, but can happen).

Title: Decent as long as your not using high level input
Review: Works pretty good, though definitely not the 400w at 2 ohm claimed. under powered for the 2 ohm 350w rms sub I ran it on. Did not work at all on built in high level input, extremely quiet using external convertor. ok volume with low level input. Amp gets quite hot but did not have any reliability issues in the 2 weeks it was installed before returning.

Review: Se lo puse a un subwoofer 8″ skar en 2 y 4 ohms 250rms, no pudo levantarlo en ninguna configuración, a lo mucho con 14v sacaba 110watts rms, por el precio se me hace acorde pero no esperes mucha potencia de este mini amp. Eso si cabe en cualquier lado y ni se calienta.

Review: Excellent power for running a single subwoofer. I would not hesitate to use it on a ported 15.No, it won’t blow the doors off your car obviously. But for the price it has a remote level control and subsonic filter. It “feels” like it puts out an honest 150 watts.For 85$ you won’t find anything better and it’s extremely compact 👍

Review: if you’re building yourself a home theater, this thing works perfectly! I’m using a generic 12v 6amp power supply and it’s running perfectly for me with no more bottoming out like with the less than adequate fosi amp that was installed previously. this is a no brainer for the price imo, it drives my sub REAL good!
