Fosi Audio BT20A Bluetooth Stereo Amplifier, 2 Channel Home Audio Component Amplifiers for Passive Speakers, Mini Class D Amp Receiver 200W for Indoor/Outdoor/Garage/Ceiling/Bookshelf Speaker

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!

Box arrived undamaged. Easy to set up. I have 2 outdoor wired speakers and needed an easy way to use them via blue tooth. Sound quality works great. As others have mentioned, I turned up the volume to about 80% and the base to 100% and the treble just a tad and now it's sealed in my vented weatherproof enclosure under my deck. I had 4mm banana plugs on my speaker wires and they just pushed right in. The hardest thing for me was to wire the components to the backer board of the weather box, which has nothing to do with this product. I purchased this baby with a coupon for $60 including tax which is a great price for this solution.

This is a great little (and it is tiny) Bluetooth receiver. We just bought a house that had inside and outdoor speaker pairs.I found that the wires for each pair terminated in the utility room. I had no way of using these speakers like I wanted. But I found this little powerhouse and am now able to listen to music and podcasts from a Bluetooth connection.Note: Because I had two different pairs of speakers, I also purchased this handy little selector switch:https://www.amazon.com/dp/B000NJHAFQI hooked up the speaker wires to the selector switch, and then with a couple of spare wires tied the selector switch to this receiver and it works like magic without the possibility of impedance damage to any of the speakers.In all candor, I used ChatGPT to figure out all of this. The AI selected both products and walked me though the installation. Pretty slick.Great results!

I've purchased 2 of these. Both work great, had them over a year. each one is wired to 6in polk audio speakers. 2 in the kitchen (one receiver) and 2 in the back porch (another receiver). Sound great in the kitchen, outside in the patio it rattles, but that's because of the metal it's cut into. (I have a barndominium). The only reason for the 4stars is because I have a problem staying connected to bluetooth when I am outside with my phone, it gets real static-y. (both receivers are in my kitchen in a cabinet). but i'll blame that on the metal walls and sprayfoam it has to go through. All in all a great product, i will be buying a tthird one here soon, for my pool patio!

Very compact in size because Class D amplifiers are so efficient they produce much less heat loss. I'm using the amp for rear channel surround sound which don't need to be as high in quality or low distortion as the front channel amp. I paired it with a wireless transmitter/receiver set so as not to have wires running across the room. YouTube has lots of video's to review so you'll know what to expect. I would buy it again as it is a good value.

Buy this receiver if you’re like me and have old (but nice) bookshelf speakers …. That you just don’t know what to do with and can’t bear to throw away.So I used this receiver to set up a stereo with em in my garage. Boom! Man Cave sounds great.Phone connected via blue toothright away. Perfect.

I ended up buying two because I liked the first one so well. One is outside on a covered patio running Klipsch AW-650 speakers. The other is inside in a small room running some Infiniti RS3 bookshelf speakers. I have been impressed so far in the two months that I bought the first one.I think of the two, the Klipsch, which are 4 ohm, sound better.

Got these on sale and could not be happier. Fosi is killing the cheap power amp game. The bt source takes priority over the single rca, which I prefer. This will power any 4 ohm speakers you have and even some higher ones that aren't power hungry.
