Fotos principales no conciden con las del producto.,.... No lo eh instalando pero a como lo veo no creo haber hecho una buena compra ... Dejó la foto de como se muestra y la otra en dibujo como llego

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.

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 👍

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!

Powers my 10 inch home theater car subwoofer with the right amount of power. Easy to adjust gain controls and is powered by a 12 volt power supply I also reviewed on here. Great match of power, small and compact. Well worth the money. Sound quality is punch and perfect for my subwoofer. Took 10 minutes to install and works great!
