Audio Amplifier Board with BT 5.0, 10W 15W 20W 2.0 Dual Channel Stereo Wireless Mini Amp Module with Protective Shell

This little amp is AWESOME!I bought it to install on my 1983 Goldwing to pair up with a cheap Bluetooth MP3 player to give me some tunes while riding.I tested the amp by hooking up a couple of speakers and an old 15V laptop power supply. This little thing CRANKS!I can't wait to install it on my bike!I paired the Bluetooth with the MP3 player the first time, and now it automatically pairs flawlessly every time I turn on the MP3 player.Amazing, awesome little piece of tech. I'm really eager for warm weather, this is going to make riding so much more fun.I'll be hooking the amp up to a "switched" power source, so that way it fires up every time I start the bike, and I can just carry the MP3 player in a pocket or Velcro it to the fairing. No need for any wires or connections.This is going to be a fantastic way to add tunes to my riding!I'm STOKED!

This little thing is foreal! and it pumps out some nice sound for such a little bluetooth amp. It's very small and delicate, but boy can this thing handle some power. I've had a 200w subwoofer and a 100w midrange woofer and this little Amp had no problem,never over heated or had any problems with it. Definitely worth the money because this unit and 2 20-30w speakers and your in business. I have 2 of these and to of a different kind and I love them. For the chump change they coast! It's way,way,way worth it to get some while there hot and the price is low.

Others complain about the Bee-Doo sound when first powered up. I didn't find it all that annoying. But then again I'm using smaller speakers (out of an old computer monitor - not bad sound by the way) and I'm powering the module with 12VDC, not 24. I'm sure it would be louder with higher voltage, but for my purposes 12V is just fine.I've built a gift for the wife. She likes to play her music from her cell phone. Doesn't sound good that way at all. So I took some wood and built two tiny speaker boxes and mounted the module inside one of them. I'm impressed with the sound and performance. Haven't given it to the wife yet, it's for her birthday coming up in the next few weeks. So it hasn't had much of a workout. But the testing I did - it sounds good. It's not a BIG system so don't expect concert hall sound. But with the right speakers it's pretty good.

I don't often buy things that don't yet have a review, but at this price I figured I go for it. This thing is awesome. It is tiny, less than half the size of a credit card. And it is loud! Also, the Bluetooth antenna is great! I can walk around my house with my phone and I haven't gotten it to cut out at all. I have a Bluetooth speaker that cuts out if I just go to the other room.I ran it into 8ohm speakers with 24v\1a and 12v\5a power supplies I have on hand and both work great. I did notice that the board ran quite warm with the 24v power supply. The instructions do say that if you run 24v to use a heat sink. The board itself is very neat and the black PCB is a nice touch. The included acrylic and standoffs are a nice touch.I only have two criticisms, which are minor especially considering the price:1) the included DC plug is wired incorrectly. The red wire is negative and the black is positive. The board itself is marked correctly. I could not initially get it to work due to this. I sent an email to the address on the documentation and they responded very quickly and let me know if the problem. I swapped the wires and it worked perfectly. The support person said that they are working to update the included documentation.2) The beeps that let you know it turned on, volume maxed, Bluetooth connected, and Bluetooth disconnected are fairly loud. The nice thing, though is that the volume maxed beep does not interrupt the audio stream.I've only had this thing for a few days. I will update it if anything drastically changes.

BT identity shows as "XinYi" which didn't match the instructions, but other than that it's great for the price and size. Matched up with 3.5" speakers for $26 and I've got a more than decent stereo in the dash of my old truck for less than $40. Not a powerhouse, but for a truck cab plenty of sound, and of course you can amp it if you need morehttps://www.amazon.com/dp/B07HKQ56FH?psc=1&ref=ppx_yo2ov_dt_b_product_detailsUNFORTUNATELY, this thing worked great on the bench, but died in a day once it was installed in the truckI’m assuming it needs cleaner power than an old alternator can supply, but I’ll never know

Honestly....I love tinkering with this thing. I power it with 4 18650 lithium batteries in series. These are 3.7V nominal. I run them through a DC to DC converter (model number LM2596) just to make sure this amp gets the 12V it likes.I've been using the amp to power a Dayton Audio excitation speaker. It's one of those speakers that turns nearly any hard thin surface into a speaker. It's so cool. So now, my little (battery) to (power converter) to (BT amp) to (speaker) setup is all self-contained and wireless and fun!I can walk around the house attaching it to stuff, then play some Pandora music through it.PROS:As other reviewers have stated, this is a beautiful piece of hardware. I LOVE how small and compact it is....it's about the size and shape as an old ZIPPO cigarette lighter. Very sharp looking, high quality appearance. It pairs up very quickly.CONS:I would like it if the "I'm paired up!" signal were a little quieter. It is so loud it is startling.

This little amp.is powerful beyond its wattage. I cobbled together a small bluetooth speaker box with this and some speakers i had from a dead Bose soundbar. Little thing will run you out of the room! The amp works quite well with a 2ah 12vdc lithium battery. Couldnt ask for more than i got for the price.

Tiny little amp puts out a big sound. I was looking for something unique to make a portable amp to use with my projector when showing movies outdoors. This was perfect for my purpose. Mounted in a 6” long piece of aluminum angle that I had sanded to give it a hammered look. The amp is mounted with a small piece of Velcro to the inside of the angle. The angle lies on its two long edges with the amp underneath. I drilled holes in the angle for two speaker outputs and one hole for power in. Very handy that the power plug comes with the amp. Despite the diminutive size of the amp it pumps out a large volume. More than enough to add audio to movies shown outdoors.

¡Este pequeño amplificador funciona muy bien! Yo lo usé para conectar un par de bocinas exteriores y lo alimento con música vía Bluetooth desde el móvil. Estoy usando un eliminador de baterías de 12 V y 1.2 A y funciona muy bien. Es realmente muy pequeño (como la mitad del tamaño de una tarjeta de crédito), por lo que se puede usar en cualquier espacio. La instalación no tiene problema alguno y en menos de 5 minutos queda listo para funcionar...Recomiendo hacerse de un eliminador de baterías que tenga distintos tamaños de salidas para no errar al seleccionar el necesario para la entrada del amplificador.

tarjeta de audio y Bluetooth de buena calidad, la etapa de audio no es de buena calidad, se satura a bajo volumen, lindo juguete.

Use este amplificador con un par de bocinas. Y no me gusto mucho el sonido. Era algo agudo. Mas agudos que bajos. Su coneccion con otros dispositivos por medio de bluetooth no es muy buena. lo conecte a mi laptop y el sonido se cortaba mucho. Luego lo conecte a mi TV y lo mismo, el sonido se cortaba mucho y se podia oir mucha estatica. Luego lo conecte a mi celular android y alli si se escucho bien. Pero si alguien caminaba entre el celular y este ampli DAMGOO el sonido se cortabe. Despues lo conecte a mi iPhone y con ese funciono muy bien, no se cortaba el sonido ni cuando alguien pasara entre el cel y el ampli.veredicto: No tiene buena coneccion bluetooth con muchos de mis aparatos. Solo con el iPhone establecio buena coneccion bluetooth. La calidad del sonido es de calidad media. Es aceptable. Solo lo usare con el iPhone por mientras. Pero no lo recomiendo, Ni lo volvere a comprar.
