Stereo Audio Amplifier for Home Speakers S-288 Bluetooth 5.0 HiFi Mini Audio Component Amplifiers Receiver 4.0CH RMS 40Wx4 Max. 600W Integrated Power Amp W/USB,FM,Adapter

I was pleasantly 😮 Surprised at How Functional this Amp is as well as the Power. Love the Features (super compact size, FM/AM Radio Tuner, slim Remote, Bluetooth connectivity <to my Cellphone>, Digital display, crisp Sound Quality, and RCA Cable output) plus the Power it delivers to my POLK Patio Speakers.

Purchased for Home surrounding system: solid case of metal (not plastic). Tested all functions except mic and worked as expected. Output power is enough for home use. Blue tooth connection is very reliable with 30-40 feet . Sound quality is acceptable ( depending on sound source). FM radio signals are little weak. USB/MP3 playback is good. Remote control well designed. Two shortcomings: 1 a loud sound comes out when switching functions and no way to make it quiet; 2 poor user manual and operation instructions.

I needed a receiver to hook up to a built in home speaker system. For a very reasonable price this actually works quite well. It did take a little bit to figure out how to hook up exactly right with my system so that all the speakers in the house worked correctly but we got creative and figured it out. Very easy to pick up Bluetooth using phone. Does have a funny beep when connecting but it’s not a deal breaker. Hopefully this has longevity.

I use these units to add Bluetooth and FM radio to 1930s and 1940s vacuum tube radios. Tap the output into the volume control and there we are...good sound, adds new life to old AM/SW radios. Not perfect but fairly good.

Love this product! I can turn my TV up louder. I can Bluetooth stuff. It took away a lot of crap in my front room that I didn't need

I'm comparing this to a 3 channel 3ohm 750 watt LG I bought for 60$ used 8 years ago, it's sufficient but didn't seem to have an internal fan so I do fear it'd overheat in a car application, and it doesn't draw enough power or simply isn't the best quality, don't get me wrong I'm running some serious speakers and does well with a couple 8inch speakers but doesn't have enough gain and crackles as full power, as well as it doesn't handle sound booster well either. Overall for 50$ it's not bad

This is working out great for my built Bluetooth speaker I have built. I have this paired with 4 Pyle 3 way coaxial speakers that are 6 x 8. Nice strong amp. I also love the external Mic feature.

For such a small package the unit performs above expectations. I was looking for this kind of amp for outdoor projection movie night. It is amazing how much the op amp chips have been developed and how good they are. Have it hooked up to tannoy outdoor speakers that are high end components. At 12 o’clock it was way to loud, enough that the surrounding neighbors would not be happy. Blue tooth was fast to connect and the stereo separation was huge. The FM locked on to 40 channels with real clarity take note this was outside not inside the home. Couldn’t tell if FM mode was stereo like you could hear in BT mode. Hooked up to a Rotel tuner to the Line input, could of been a cd player, cassette deck anything with rca jacks. If you have a built in pre amp in your turntable your good to go with line input. No pre amp, you will need the addition of a pre to use your table. Tone control worked way better than expected. The treble knobs performed better than the bass control. The bass control is ok but depending on the music it can be lacking. It has no protection mode you want to blow a channel short the speakers wire together and she will most like have a component failure in that channel. 30 dollar throw away component is just unbelievable cool unit to play with. I can finally see myself buying high end class D amps with changeable op amp chips they come that far in performance.
