Stereo Home Audio Amplifier Receiver AK45, 400W Bluetooth 5.0 HiFi Stereo Power Amplifier 2.0 Channel RMS 40W x 2 Home Audio System with Remote Control Amp W/MIC,USB,RCA,FM Radio

I like this, has all functions + remote and using old school wired speakers. Goes loud enough with both volume knob and remote volume. For what you pay for, very much worth it. While not perfect, I observed the following: no headphone plug/jack, USB did not have random/shuffle and most importantly, when you power on with switch, the volume defaults to 30 (loud) be careful. Also, no memory save for settings except for USB.

Works very well with my Elimavi 30W*2 speakers! Blue tooth connects great.

This is so cool! I love the idea of a mini stereo amplifier. It's just right for a small bedroom where surround sound and multiple inputs are not necessary, and it's very affordable. For my use case I have a Sony Bravia tv with no headphone output. I could connect my 12" soundbar to the audio output with a RCA to 3.5mm adapter, but the tv's volume buttons don't control it. This amp, along with a bare wire to 3.5mm adapter, solves the problem and the remote control allows to control volume from across the room. It took a few minutes of adjusting the volume levels of the amp and mini soundbar to prevent static but I got it worked out and it sounds very good. The FM tuner is nice and I don't expect to use bluetooth or usb inputs. I find the volume knob sort of sets a maximum desired level and then the remote control buttons adjust the volume within that level. Update: Knocking off a star because each day, after being off overnight, it had static again without changing any wires or volume levels. After a few days it became impossible to eliminate the static and even started losing sound from either left or right. I'm not sure if it's a side-effect of the 3.5mm adapter or if it's something internal.

Bluetooth, fm, audio in, got some speakers ?Luv it, had to buy an fm antenna.

I'm using the amplifier with four ceiling mounted speakers. For music it works great. For movies, it's terrible. There seems to be some kind of automatic squelch that is too slow to turn the sound back on after more than a second or two of silence. When watching a movie that is quiet other than dialogue, it ends up cutting off the first syllable whenever someone starts talking. Extremely annoying.

The amp was ok but had a bad hum when aux mode was selected that disappeared when anything played. A ground loop isolator may have helped but I didn't test that because the amp defaults to Bluetooth mode whenever it's turned on with no way to have it remember the last input used. That was a showstopper for my use. Returning for refund.

Works good so far.

Very Economical Mini amp and player. Audio output is dual control with knob on unit and secondary with remote. inputs: USB-mp3/BT/Phono/1/8th/micro sd MP3. FM with wire antennae. (choosing stations is the least best part of this product for me) (but only 20 bucks) I don't normally listen to any radio anyway. Found my USB MP3 playlist right away. Remote. You'll need to supply speaker wire for output to your speakers. (4-16 ohm) My test worked great on 8 ohm 75 watt speakers each. (more like 24-30 watt total). Good bass and treble controls. No balance controls for left and right. Some complained the unit quit after a few months, for $20 I thought I'd try it anyway...gets $20 5 star on first use! :)
