Bluetooth 5.0 Audio Power Amplifier AK-380 400W+400W 2.0 CH HiFi Stereo Amp Receiver with USB,SD,AUX,Remote Control,FM Antenna for Car Home Speaker Bar Party-(Without Power Adapter)

Worked right away - so simple, sounds great! I'm using to drive a Pyle 50W 8 Ohm PA horn repeating songs on an SD card / USB device. Plugged in power, plugged in speakers & wow! Works right away!!! Sounds MUCH better than I expected for the cheapest device pretty much on amazon. It's so loud with 1 speaker pointing away from me at 1m away (in a garage), it's too loud to turn up over 25%. And I can still totally understand the words of the songs. Being able to boost bass (or treble) is huge. Very simple device.Draws about 0.18A at volume = 0%. About 0.4A at 25% with 1 PA horn. REALLY happy. Exactly what I wanted!!

Great little device, have a few installed and no problems so far.

It does not come with a power cord the 1st cord didn't give it enough power. The 2nd power cord I found made it very hot. I tried a 3rd power cord and it blew up.

It's ok for what it is

The media could not be loaded. It is small and works just the way it should. It has 2 separate volume controls which allows it to get very loud. When I was trying to hook it up, the remote volume was at 00 and the knob didn't do anything so I thought it was broken. Once I turned the remote volume up then sounds blasted out because i had the knob cranked up. The Bluetooth works for about 40 feet. The radio antenna it comes with works very well when you hang it up. The input allows for RCA or a 3.5 audio auxiliary (headphone) jack. You can adjust the sound with basic treble and bass knobs which work relatively well. I like a lot of bass so it's a tad lacking but I do have small speakers connected.

I've been using for about 6 months and still works perfect. I have it hooked up to 4 6.5" speakers and it has no problem getting very loud

The Bluetooth 5.0 Audio Power Amplifier is great !, For my use our older flat TV did not have a output RCA volume connection, but did have an optical out, We used the optical out with RCA audio cables connections and the device worked perfectly. The remote volume controller is perfect.Over all a great product.Note :--> I also use the USB connection to play my stored music.

This little guy packs a punch. I love the simplicity. Never used the sim card or USB but it's been 2 years with my bookshelf speakers, I love it
