FacmoguF900S 160W Mini Bluetooth 5.0 Power Amplifier, 2 Channel 80Wx2 Stereo Hi-Fi Digital Amp, Portable Wireless Audio Receiver Sound Speaker Amplifer, AUX/USB/Bluetooth Input & 12V Power Supply

The media could not be loaded. Sound is very clean, crisp, easy and simple to install. Connects to my phone with Bluetooth, simple, vol can be adjusted using the phone or at the Bluetooth amplifier itself. It’s small, takes up minimal space. I’m using it to replace a radio that didn’t have Bluetooth, in my Sauna, Will see how well it handles the extreme high heat, but so far works beautifully, should be able to keep hatch closed and it be ok, if to hot, will route wires down close to the floor. Will update this review in a few month. So far good value.

I have a very specific use case (whole house audio) but wow... I'm very impressed! Here's my take on how I'm using it...Whole House Audio Project:We build our house about 11 years ago and wired it for 12 zones of audio. I have 4-wire speaker cable and CAT-5e network cable running from a central location in the basement to a single gang box in each room. Then, from the gang box, I have speaker wires running to the ceiling locations.In the 11 years we've been here, we never pulled the trigger to purchase the "traditional" system (multi-channel amps, in wall controllers, speakers, etc.) We've been quoted well over $10,000 for all 12 zones in the past. Even a DIY solution online would run nearly $4,000 without the speakers (HTD Audio's Lync system with keypads.) That's just not worth it to me.Being a Google fan, I set out to build a system using Google's Chromecast Audio devices, amplifiers, and in-ceiling speakers. I ended up purchasing this Mo-gu F900 amp for each zone in the house and it's been working perfectly! I'm at about $139 per zone and absolutely loving it!I can stream to each zone (from Pandora, Spotify, Google Play Music, I Heart Radio, podcasts, etc.) and control it from an iOS device, Android device, computer, Google Home, etc. I can have different sources streaming to different zones or group any zones together. It's incredibly flexible and easy to use.Here's the setup (per zone):1. Google Chromecast Audio ($35)2. Mo-gu F900 Amplifier ($31.99)3. 82C 8-Inch In-Ceiling Speakers ($35.98 each, $72/pair - Available here on Amazon)And here's the installation details:1. Install the in-ceiling speakers.2. At the gang box, connect the speaker wires running to the ceiling to the 4-wire speaker wires running to the basement3. In the basement, connect the 4-wire speaker wires to the F900 (and plug in the F900 with the included power supply).4. Also in the basement, connect the Chromecast Audio device to the 1/8" jack on the F900. Plug in and configure the Chromecast Audio.5. Turn the F900 on and set the volume knob about half way up. You can use the Google Home app to adjust the final volume of course.6. In Google Home, select the Chromecast Audio device and edit the settings. Make sure you name it to the room it's located in. Also, adjust the treble and bass settings. I put both up almost all the way. The F900 can handle the wide frequency range very well. (YMMV of course so set it to your taste!)7. Also in Google Home, set up your groups (ie: Whole house, Downstairs, Bedrooms only, etc.) You can create as many groups as you like!8. Using an iOS, Android, or Google Home device, cast a source to the room and enjoy!Pros of the F900:* Powerful - It's driving the 8" speakers a lot better than I thought it would. Even over a long distance (>60 ft). Just make sure you use the proper gauge speaker wire if you have long distances.* Clean - We're not talking audiophile quality here but I was pleasantly surprised on how good this amp sounds.* Simple - It's a "set it and forget it" device in my solution. I plan on keeping it on all the time and I'm not too worried about it!Cons of the F900:* Size - It's actually a lot smaller than I thought it would be. Not really a bad thing but it was surprising.* Build Quality - The build quality is actually very good but the front sticker was applied a bit askew. Not a big deal though.* Hiss - When there is no audio playing, there's a VERY SLIGHT hiss that you can hear at the speaker. I mean, VERY, VERY SLIGHT. (I only heard it when I was on the ladder putting on the speaker grills. I had to have my ear closer than 12 inches away just to hear it. I can't hear it at standing height.Well, that's it. My cheap whole house audio solution is complete and a lot more flexible than I could have expected. Grand total for all 12 zones was approximately $1,670 (not including the speaker wire). The real beauty is that you don't have to do all of your zones at once. You can build it out zone by zone. (That definitely helps when you have to get spousal approval!)Hope this review helps!

Was able to test with a set of cheaper portable speakers - similar to the old cloth-covered, 3-way ones you used to find in vans. Sound is clean and decent - probably as good as one could expect from those speakers. Volume isn't overpowering but has plenty of output for sitting out back around a campfire or throwing shoes. BT connectivity was smooth and quick. One drawback - the adapter cable they provide for USB connection is terminated in USB Male, making it useless for plugging in a thumb drive. I ordered a USB F-F adapter but not sure why they bothered to send something that couldn't be used out-of-box. If you plan to use this as a USB input, either make sure your source device has a USB female port or buy the adapter along with it. Overall, a good value with or without the cable. As for BT range, I got out close to 100' line-of-sight before I started losing connectivity. I'm guessing they put the antenna inside the plastic faceplate - kinda wish they would have added a port you plug a little stinger antenna into as I would like to install this inside a weatherproof enclosure and would be nice to have an antenna I could extend outside the box and not lose BT range.

The media could not be loaded. Nice unit, I used for an easy diy portable AMP build, using marine quick connect pigtails for the speaker connections & I can plug it into a house outlet for power OR use my cordless power tool battery + power supply converter that converts my 20v Bauer Harbor freight battery to useable 120v home outlet (limited amps and watts) but it’s within spec of this amplifier and working no problem for me. Awesome purchase I recommend to anyone looking to power a few speakers.I have sets of speakers all over the house, shop, hot tub, gym, camper ect… that quick connect into my portable amp box here when I want to use them. Because I will never be using them at the same time so why buy a million amplifiers.The Bluetooth is pretty snappy and has been working harmoniously with a lot of different devices in the time I’ve used it.The design and quality of the amplifier it’s self is far better than I could have anticipated for the price. Will likley build another one here soon enough so I have a backup.I think the sound quality is good and clear but I’m also not super snobby about having bumping bass and the best speakers money can buy. This simply works well and now I have an excuse to use any speakers I can get my hands on.

I have a set of Jamo Studio 8 Series 803 when I say it’s a perfect match for this have no complaints at all! After playing with EQ setting in my phone a little bit the sound is nice and clear the mids are incredible if you’re expecting this to shake the walls or anything it’s not made for that. For a small room or use in a garage or work area you won’t find anything more simple!
