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

Worked amazing powering my 70s realistic mach one home stereo speakers. Great sound quality and great power for its size and price. I broke mine trying to strap it to my motorcycle so now I need another one.

Great value for the quality, I use it to power outdoor speakers. Sometimes it’s left powered on outside in the elements for weeks at a time and still works great. Installing and connecting wires is very straight forward. Noise level isn’t bad but not nightclub loud, Bluetooth range is about 30-40 feet

I wanted to get rid of a large amp that I used under my desk to play some music. This little amp was a Prime Choice so I thought I would give it a try. The only strange thing was is at the time it was advertised to be 400watts per channel! When I got it and tested it I realized it is 40 watts per channel. I called customer support and told them to edit the advertisement to the proper specification. I have not had a reason to use the USB. But the Blue Tooth shocked me how nice it connected and sounded. It even has a remote controller that is pretty nice as well. This little amp serves it purpose well and I am satisfied even though it is not 400 watts.

We got this for our food trailer, where space is at a premium. It is very compact, yet still has plenty of input options. The FM receiver gets good reception, and the Bluetooth is easy to pair. The larger volume knob is very convenient, and the solid aluminum case seems like it will be very durable. At this price, this is a great value.

For the price , you get what you pay for . Works great and can turn up and down by left and right which is nice but also annoying. Sound quality is good until you go too loud but again, you get what you pay for .

Update: Arrarown took care of the missing remote, good customer service. the S-299 Bluetooth 5.0 Power Amplifier and was excited to get it set up with my home speaker system. Installation was straightforward, and the sound quality so far has been solid for the price—clear output, good Bluetooth range, and it powers my speakers well. However, I was disappointed to find that the remote control was missing from the box. It’s a small thing, but it makes a big difference in daily use, especially since the unit is now installed and not easily accessible. I’m hoping the seller can send a replacement remote so I don’t have to go through the hassle of uninstalling and returning the entire unit. Otherwise, it's a good product and does what it promises. Will update my review if the remote situation is resolved.

My requirements: Small, Light weight, sounds decent, cheap. Be prepared with a powerful magnifying glass if you want to read the manual, which is written in transliterated Chinese. Power cord is 3' long. There's no cord supplied for the 12V power input, so this was not tested. Knobs are black with a black notch to indicate the position - very difficult to read. The unit forgets the FM station when turned off. The unit shipped with the volume knob turned to max. Be careful with that initial test!!! Line input is RCA, and outputs are the old wire clamp method. Remote control uses a 3V CR-2025 watch battery (supplied). The volume buttons on the remote were confusing - they allow you to change the volume up or down UP TO THE SETTING OF THE VOLUME KNOB on the device. Bluetooth worked, but seemed to require a higher volume setting than radio or AUX input. The manual is silent on what type of microphone can be connected. I used an ancient Realistic Highball-7 (impedance 600 ohm) mic that was at the bottom of a box of unused gear. It worked OK. Couldn't get music to play from a USB memory stick at all. It just didn't recognize it. Using an old SD card did work. Is it possible that the player doesn't recognize newer types of USB sticks? USB sticks are typically compatible with older devices that try to read them. Luckily, playing from USB sticks was not something I need to do with this device.

This is a 5 star item for value sound quality and loudness however after having ordered a four channel unit and it came with Four sets of speaker terminals on the back only two of them worked. I tried speakers that were proven to work on two good channels on the two bad channels and they did not work. It is hard to find an affordable 4 channel stereo amplifier so I'm disappointed also Bluetooth was not just problematic I couldn't get it to connect but I know that's just ABT issue and it could be the player not this device If you want good sound and are happy with two channels save a buck and buy the 2 channel model As for me I went with a different brand and am using wire adapters to connect my 4 speakers to these two channels that will come on the new unit. This housing is plastic not aluminum also.
