Facmogu AK380 Max 400W Mini BT Audio Power Amplifier, RMS 40Wx2 2.0 CH Bluetooth Receiver Speaker Amp with 12V 5A Power Supply, Bass & Treble Control Music Player Sound Amplifier for Car Home Garage

Incredibly small and light. I can't say much about the quality of sound it puts out because I don't have a tester but it sounds great to me. Bass and treble knob are convenient. I have sony speakers hooked up to it and it seems to get pretty loud without loss in sound quality. No buzzing or whining coming from the speakers or the amp. The remote feels fragile but works great. Bluetooth sounds great and has minimal delay. Comes with an antenna for the fm radio and it sounds great. It conveniently scans all the channels and binds them to the number on the remote making for fast and easy radio station selections. The antenna is about a foot long but even all wrapped up it seems to get great connection. The blue light coming from the volume knob is kinda bright and annoying but stylish if you're into that. There is a nice convenient small display at the top right that shows if its on fm radio,Bluetooth, or line in. Haven't used it long but after an hour of use this thing puts out almost zero heat. If you only want 2 channel stereo audio then this amp has incredible value for the price. I came from a old 330 watt old reciever that was 15x bigger and put out 15x more heat. This amp blows that old reciever out of the water.

Bought this to replace an aging (1979?) mini component amp. Good, undistorted sound at mid range volume, fills office with clear sound. Easy to connect via bluetooth or Line In. Note there is no balance control, so no balancing for speaker distance. When power comes on, automatically connects to line in, so you have to select Blue tooth again if that is your primary use, but syncs up to my desktop tower automatically after first pairing. Appears to be well made, does not overheat with modest power levels. Plenty of power for an office or bedroom sound system, but likely not for a large room.UPDATE: Unit still works well, but I have noticed a slight delay in the audio when watching videos streamed from my computer. A stand alone Bluetooth receiver fed into LINE IN does not suffer the same delay. Likely due to "Slower" Digital to analog converter than stand alone unit. Wouldn't notice it if just listening to music.

I always get irritated when things are 'over rated' ~ obviously there's nothing 200W about it LOL, but I knew that going in. How manufacturers can throw such numbers at amplifiers and get away with it bewilders me. *that said* ~ it's probably an honest 5W amplifier, it works fine and sounds good. It does run a bit hot, but... so far it works fine. I like the simplicity of the controls (volume, bass, treble). I discreetly installed it under the dash of my antique car so I can blutooth it off my phone ~ it's nice, cheap, and simple.

This is a nice little amp that works great. I have it in my 30x48 shop and it fills it with sound. I hooked it up to some old bookshelf speakers and it has impressive power. Very clear sound. Paired right up to my phone and Bluetooth works great. It comes with a wire for the FM antenna that works well and it will automatically go through and preset channels. Nice feature is that it remembers the station channel you had it on when turned off and will be set to that one when you power it back on so no searching for the station again. Only drawback so far is that the search will preset on some frequencies that don't have stations. Not sure how to delete those as the instructions are not very helpful. Not bad for the $$

Fast service

Pay attention to the other one-star rating saying the left channel doesn't work; he's right. I got mine tonight, and sure enough, either speakers only when plugged into the amp's right channel. Just to be sure, I tested it with my multimeter. The right side is about 150 ohms, and the left is infinite.

didn't come with the power adapter as shown. came with just a usb cable--and that doesnt work right because the voltage is wrong. have to source a power adapter. rated 3 stars. have not used because of missing power cable. does power up

These are running my big speakers really well.I have a set of Tannoy i9s, which are 8 ohm speakers, meant for outdoor use and large events. They have been repurposed for my living room home theater, and this is the perfect driver for them. I love the radio feature, and the Bluetooth works very well also. Incredible quality in such a small box.

Por su precio es más de lo que esperaba, buena calidad de sonido, levanta muy bien mis bocinas que tenía arrumbadas, muy buena opción para llevar a fiestas o para tu casa, carcasa metálica se siente bien al tacto, ya tengo rato con el artículo y lo mantengo siempre conectado a la energía eléctrica no me a fallado

Es muy práctico y suena muy bien. Vale la pena.

Tamaño y sonido excelentes

Muy bueno soluciono mi problema

The media could not be loaded.  Me había funcionado bien, pero de un día para otro el eliminador y el componente empezaron a parpadear y ya no realiza ninguna función
