Fosi AudioBT20A Bluetooth Stereo Amplifier, 2 Channel Home Audio Component Amplifiers for Passive Speakers, Mini Class D Amp Receiver 200W for Indoor/Outdoor/Garage/Ceiling/Bookshelf SpeakerClimatePartner certified

I got this to run some higher end home audio speakers installed outside for the yard/pool area at our house. The speakers are $300 each and I had been running it on an older Sony coil-based home theater amp because I thought I needed the zones and independent volume controls/management for tone/eq. The amp in the cabinet indoors was putting out quite a bit of heat when it was powered on whether they were in use or not. The wiring was a total mess and I bluntly didn't enjoy dealing with it. I went in to this project assuming I was going to get a Denon, Onkyo, Yamaha, or some home audio mixer board + eq, or something fancy with roughly $2k budget... I was on struggle street trying to piece it all together. I only need a simple input amp. I have a cheap class T amp in my garage that works for what I am doing there, but the audio quality is trash. I rolled the dice and picked up a few of these and man, they blew my mind. They have a lot of punch/power and the audio quality is REALLY surprising compared to the old stuff I had. The BT connection is ROCK SOLID. A lot of these cheap china BT interfaces are trash and buggy. This thing pairs right up and is solid and reliable. I'm waiting on the splitters to feed the source to all of them, but per zone, they're superb. Super straightforward install and good labeling, pair with FosiXXX and go for BT. It's a small, light package and the box it comes in is pretty good for it's weight and has some heft. Not sure whether the weight is from the case or components, but it's a mosfet so we'll see about heat dissipation down the road and whether it does a thermal cutoff or not. I might end up getting more for the garage after a few sessions in the backyard. I was pleasantly surprised!

As an person who’s used to high-end tube amps and large receivers, I wasn’t expecting much from such a small, affordable amp.No, it’s not going to replace your multi thousand $$$ boutique amp for critical audiophile listening or bragging rights, but for 99% of the population or normal TV, movie, game and music listening it’s awesome.I loved it so much that I ended up buying a second one.This little powerhouse easily drives my JBLs and KEF LS50 speakers to impressive volume levels with crystal-clear clarity. It’s perfect for my living room TV setup.The Bluetooth feature works flawlessly. I also appreciate that it comes with a remote. For the price, this amp is a steal. If you’re looking for a compact, budget-friendly amp that still delivers excellent performance, I highly recommend it!

i got this to replace the final stage on the sony amp that blew it's left side. the sony still works as a preamp and switcher for the turntable, tv and music streamer i have so i didn't have to redo a lot of wiring. all i had to do was run a line from the tape-out on the amp and move the speaker wires to this little guy. all my controls and remotes stayed the same. nice bonus is i now also have bluetooth. it's not as powerful as my original amp and you can't drive it as hard; ive a feeling if you do, something will blow as the components are rather small. it happened on another, similarly built amp. the sound quality is adequate, esp in this age of earbuds. my wife doesn't notice but i can definately tell there is a midrange bias, even with the tone controls. still, it's good for it's size.one thing i really like is the bluetooth addition. the sound quality is good and there is very little spurious noise. it is a preferential connection so it will override anything coming in from the AUX inputs. i wish there was a button to switch but as is, just turning off the bluetooth on your phone will cause it to automatically switch back.overall, it's a good little unit. i wish it were closer to a $60 price point but build quality seems good and sound quality overall is great for this little guy. i'll probably buy another one to use as a portable outdoor entertainment like another reviewer did.
