Fosi Audio BT20A Bluetooth Stereo Amplifier

Works as expected

I bought this to use my outdoor speakers and they sound fantastic. Highly recommend as it makes it really nice to play music from my phone with Bluetooth when on my patio.

BT20A added to low power garage with Echo

I plugged in my FOSI, stereo chord from Echo. Got the treble and base set. Driving Yamaha Outdoor speakers sounds great in my large workshop. Turn on my phone to send music via bluetooth snd it switches automatically!

Very simple to use

These amps are veey simple and robust to use. I have bought over 30 of these amps and installed in my customer homes and VRBO rental property's. They are great because when someone who is connected gets out of range for a given time, it opens itself up for the next user. There is no need to press a button to clear the last user and open it up for the next user. If you were already paired before, it is still in your settings to reconnect again.
