Works great!
Anthony Peters✓ Verified Purchase•October 8, 2023
I've used it for 2 weeks and it works great. The only complaint I have is no password on bluetooth. I purchased on sale and it delivers a descent amount of power for less than $90. I am currently using it as an amp for bookshelf speakers (JBL LX22). I bought it for a low cost alternative and I'm glad I did. When I replace my receiver this would make an excellent garage amp.
Please add a optical input

Main issue is it should have an arc HDMI input or optical or both. The main advantage to this is its small size and low clutter. Which requiring another $20 adapter eliminates part of that.
But you can get better sound quality with this than with a $600+ sound bar for like half the price Once you factor in $100 for a couple bookshelves and a $100 for a sub.
Also they need to add idents for the bass/treble. Instead of "guessing" the center
Using the included adapter I would guess power outage would be around 40-45 watts for the L/R at 8 ohm and I'm running the sub at 2 ohm, Probably get 120 watts or so. They also don't appear to sell an upgraded power supply for this. I'm using it in a large living room and its not enough power for rock concert loud levels. But it is enough for most people and reasonable levels

Fosi 2.1 amplifier
Flatlander✓ Verified Purchase•September 10, 2023
I installed this amp for my desktop computer, installation was easy and straightforward.
I doubled my old shelf speakers and passive subwoofers. Meaning I have two stereo speakers on the right side and two for the left, both front and back, and the subwoofers are one in the front and one in the back.
This amplifier can drive those speakers and subwoofers to ear deafening levels without distortion.
I first tried the wireless Bluetooth setup and it went flawlessly. The sound was great. The amplifier is right above my desktop so I opted to plug it in directly to the output of the computer instead.
I am very happy with my purchase.

Plugs right in, just works. The crossover covers a great spread, in the circuit after bass volume control. So you can adjust what sounds good for your speakers, and send the rest to the sub to munch on. The bluetooth doesn't auto-connect, you have to select it, which should be the standard. This replaced a different brand/model that would take over from earbuds, no matter the settings in my phone. We would have to power it off to disconnect. This one works as you'd expect. Great bluetooth range too. Very pleased with this unit, will likely buy more. Only downside- the terminals really aren't built for larger than about 16awg. I got 14awg in, but it wasn't pretty.
Much Recommend

Crystal clear sound on the two mids channel, any 2, 4 ohm speaker with around 150 watts output will work great. I using two 4 ohm LG stereo speakers from a system. I am able to get good mid bass from it as these speakers are in box. With this amp I am able to adjust my mid bass and treble to my liking. The amp could also power a Sub exceptional well. I purchase a 6 inch audiopipe sub(Audiopipe TS-CVR6 Subwoofer 6-inch Woofer 150 Watt Max 4 Ohm DVC 1.5" 4-Layer Dual Voice Coil BASV) and a 6 inch box. We wired the sub for 8 ohm resistance. The amp allows volume control of the sub and frequency. It hitting high and lows like a cinema. I set my sub volume to maximum and control the frequency to my liking. As with any integrated system the RCA inputs gives a higher power output. This small amp is very loud and clean. . . Good quality banana jack heighten the appearance. Bluetooth distance is very good and this is a amp I'll recommend for anyone who loves music.
Negative is the Amp get really hot but a small USB fan takes it down to room temperature. . .
If you leave the amp switch on the the amp remains hot. . . These is minor issues for me.
