Enhanced Bluetooth 5.0 Amplifier Stereo Audio Receiver, 2 Channel Mini Hi-Fi Class D Integrated Amp for Home Passive Speakers (Model: BT20A-S) Review

I have a 100W BT20A-S model and am using it to power a pair of Polk RC80i ceiling speakers under my pool area patio. I've had it for almost a year. Great Bluetooth connectivity and range. I installed it in the upper part of the kitchen pantry under the ceiling. Good performance outside very little distortion good sound. I haven't been able to find anything in the literature that says if the power rating is peak power or RMS power. I believe those are peak watts, so 100 watts peak is 70.7 watts…

Does what is expected. I can Bluetooth connect a Revain Echo and stream music to 2 pairs of 50w outdoor speakers to fill my yard with Disney music while my kids play (or rock out while my wife, I and friends play). Easy setup, reliable Bluetooth connection, crystal clear sound at moderate volume. The speakers crackle at high volumes, but this amp isn't rated for 4 speakers and I don't need my neighbors to hear my music. The only con in my book is the big black power supply. It's bigger than an…

So I got this box because it's so cheap. It was an impulse buy. I connected it to replace a 30 year old Onkyo receiver that didn't support Bluetooth (I recently set up a paid Spotify account). I just wanted to use it as a Bluetooth repeater while considering something more expensive/full featured. I am so pleasantly surprised at how well the Fosi box works! This $80 amp is eye-opening. Notes: I use a small Boston Acoustics satellite speaker (which I got with the Onkyo receiver mentioned above),

I bought these two power supplies for Polk Audio Atrium 6 speakers that I have installed in the back of my house. My goal was to allow anyone with a Bluetooth connection to play music while sitting outside. near the swimming pool. My back deck is about 100 feet long and 80 feet wide. I placed this amp about halfway down the deck. It's also important to note that the amp is indoors and actually in my HVAC room. This room is fireproof and has fairly solid drywall and insulation. I was concerned…

I like this baby very much. Possibly the best $60 purchase I've ever made. I listen to a wide range of music from modern pop to classic rock, Bach music, medieval music etc. And I bought this for a small inexpensive bedroom system that will allow me to stream music from a tablet, laptop etc to a small amplifier and speakers are on the dresser. It's perfect for that. HiFi purists may point out that this is a Class D amp - in my younger days :-) I have repaired and sold stereos and in the process

Except for the long-term quality aspects, which only time will tell, I can sum it up and simply say buy this unit. I like the sound produced by this device. I am very happy with this purchase. I needed to find a replacement/alternative for an old school (18 year old/Panasonic) RIP receiver that did double duty for music and home theater. Panasonic used 2 high quality front speakers and a decent 12 x 20 center speaker in the room. Overall sound quality was very good with the exception of the…
