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

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.

Purchased two of these and they do what I expected them to. I really like the small size which can be mounted anywhere.And wont take up much room. I run each on a 12v 2a power supply and they work flawlessly on the application that I use. The volume does slightly distort a bit at higher volumes but I attributed to the speakers I washed using, more specifically the crossover as well as the power supply. I'm sure with a 20v or higher these will sound better since they are rated up to 24v. Note that they do become pretty warm with the higher voltages.

I was thinking of taking off a star due to the assembly required for this but I have changed my mind and I now think it offers needed flexibility.I concur with the other posters. Loud and just worked.

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.

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

I didn't expect it to be so small, but it works great!

I have some old Kenwood speakers that I have had since I was in the Navy a long time ago. These speakers are over forty years old but still look good. I was considering throwing them out because hooked up to my receiver they sound bad. I bought this little amp and hooked them up with just a 12V power supply and they sound great. They sound like they always did. Since the amp was so cheap I bought two. They other one I hooked up to some shelf speakers in the bedroom and they sound good too.

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.
