Audio Power Amplifier for Home Speakers -S-299 Bluetooth 5.0 Power Amp 4.1 Channel RMS 40Wx4 Subwoofer AMP DC 12V/5A Mini Integrated Digital Amplifier with USB/SD & AUX Jack

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.

Simple design, great value easy Bluetooth connectivity compact yet powerful, sound can easily be dialed in to your preference

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.

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 .

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.

Works well with my old Sony HIFI speakers.

Lo bueno: Estoy gratamente sorprendido de que algo de este precio me rinda de esta manera. Estamos de acuerdo que no vamos a esperar la calidad de un receiver de más de 10 mil pesos de alguna marca establecida, pero para su costo está más que ok. Tiene bastante potencia, el aparato en sí es pequeño y la conexión bluetooth es buena. En mi caso lo estoy usando para reemplazar un viejo receiver marca Pioneer de 1989 que empezó a distorsionar el sonido del lado izquierdo. Lo uso con unas bocinas sony que solían ser parte de un minicomponente de los años 90, que la verdad me ha salido buenísimas con casi 30 años de servicio ininterrumpido. Estos a su vez están conectados a mi pantalla que a su vez está conectado a una Mac Mini 2014 donde veo todo: YouTube, clarovideo, escucho música, etc. La calidad del audio con este setup es cumplidora , con gran potencia, y el hecho de modificar graves y agudos desde este amplificador está super. La conexión bluetooth hasta donde pude ver es rápida y estable desde una distancia corta. Tampoco nos vamos a ir a hasta la cocina. Lo malo: Probablemente, mucha gente no lo note; sin embargo, aunque la calidad del audio es buena, me parece que sí existe una ligera distorsión en la música en los agudos de manera constante, aunque casi imperceptible, y otro tanto en los bajos cuando le subes demasiado a una melodía con mucho punch o mucha compresión (por ejemplo algo de Bass House o un sabroso Death Metal), pero en mi caso pude ajustar y ecualizar desde la Mac Mini usando apps como Jriver Media Center o IINA. En películas y videos con diálogos no sentí ningún problema. Lo feo: El controlito es un buen detalle, pero el volumen desde el control es digital y se maneja independientemente de la perilla, y pues no lo veo útil para mí, ya que lo manejo desde la TV. De igual manera, la radio, la capacidad de escuchar música desde un sd o pendrive, son opciones que quizás a alguien se le haga interesante, pero de esto no puedo comentar porque no los uso, ni usaré para nada. Otro punto es que no entiendo la obsesión de los fabricantes con los leds azules ¿no podrían ser blancos? En resumen es un buen producto, ya veremos cuanto dura, y cada quien puede tener una experiencia distinta dependiendo el tipo de bocinas y las fuentes de sonido que utilicen. Para aquellos que no quieran gastar demasiado y tengan unas bocinas por ahí volando, es una gran opción.

Its 4.0 channel only

Best in this price works well for celing speakers
