AK-380 USB SD BT.C FM AUX Audio Power Amplifier 400W+400W 2.0 CH HiFi Stereo AMP Speaker Bluetooth 5.0 Amp Receiver with 12V 5A Power Supply,FM Antenna for Car Home Bar Party

I was pleasantly 😮 Surprised at How Functional this Amp is as well as the Power. Love the Features (super compact size, FM/AM Radio Tuner, slim Remote, Bluetooth connectivity <to my Cellphone>, Digital display, crisp Sound Quality, and RCA Cable output) plus the Power it delivers to my POLK Patio Speakers.

Small and loud for a receiver nice..

Nice compact

Should work just fine

I installed this on the wall of my shop. It works and sounds great in a shop. Back in the day this amp probably would have weighed 20 lbs. I folded a little shelf and stuck it on the wall above the outlet. I mostly use the mp3 thumb drive, but the bluetooth and FM radio also work great. The downside of the bluetooth is when I walk away with my phone in my pocket or go into another room it messes up my tunes. It does not play .m4a format music on the USB drive. If you use itunes you will have to reformat them to MP3 to play on this amp. It's not hard, VLC media Player will do it. Pay attention to this, I'm saving you a huge amount of time and frustration figuring out why some songs play and some don't. Enable extensions and check for format. I run the volume between 20 and 25 percent most of the time when I'm by myself. I have to turn it down or off if I have company. I has a remote which I never use as I store it on the top of the unit. The controls are dead simple. good luck Jim

Purchased this in November 2022 and set it up to run the back patio speakers. It was enclosed and completely shielded. Would only turn it on when it was used- about 1 day a week for a few hours. It really did not get used much.Last week- the entire left channel output died!! Had to rewire all the speakers on the right channel. Will continue to use it until it dies completely- but it probably won't be long now.Update 08/31- The seller has reached out and they are replacing it! That is awesome!!Update 09/04- Recevied the replacement amp and that is all good. Decided to open up the old one and see what was going on. Immediately found the 3 IN5399 diodes had burned up. Went ahead and replaced them all. Then noticed this thing was running 0.33UF capacitor. Went ahead and replaced those all with 1UF capacitors. This amp sounded good stock. But now..... NOW, after this simple repair / upgrade it sounds freaking amazing!! The bass really pounds now.

Needed something small that could drive my speakers at my office so I gave this system a shot as it was so inexpensive. Got it in, unboxed it, plugged it in, and hooked up my Micca Bookshelf Speakers.I was floored at the power of this little amp, the clean sound (no hums or ground loops), and the ease of use. It’s quite impressive. With the capability of screwing this in under my desk and running cables over the back, it keeps my desk clean and gives me solid sound.The functionality of the Line In is clear, the Bluetooth is easy to access and pair, and the radio has a decent pickup capability when the included antenna is plugged in. It’s a really great system for the price and the size is absolutely perfect!!! Can’t wait to try it with a couple of deep full range speakers later this week!!

buena, bonita y barata si tiene potencia algo decente aunque cuando le alzo el volumen y lo quiero exigir se calienta y distorsiona sonido, para un volumen intermedio o para una habitación pequeña o mediana si esta bien.
