The large heat sink can quickly release heat to ensure that the chip can stably output large-scale power and avoid damage to the chip.
Dual TPA3116D2 Chip
Launched by TI, with very high index parameters. The highest modulation frequency can reach 1.2MHZ, and the high-power output distortion is less than 0.1%
Treble &Bass Control
Independent adjustment of high and low bass, you can adjust the high and low bass to your liking.
Easy to Connect
You only need to use thicker speaker wires to connect the speakers easily, which is easy to operate.
- Warm Reminder:
The power switch on the board is a standby switch. After the switch is turned off, the machine is in a low-power standby state. To completely turn off the power or unplug it for a long time, you can unplug the DC plug on the machine. Properly increasing the voltage or reducing the speaker impedance can effectively increase the output power.
- Is it durable? This is beyond doubt!
This amp board has 4 kinds of protection mechanisms: overvoltage protection, undervoltage protection, overheat protection, short circuit protection, which means it is not easy to be damaged!

This is a great little amp for some garage speakers. It doesn't come assembled so that is something you'll have to do. Not a big deal. Plenty of power to drive my bookshelf speakers and they get loud.I tested the bluetooth and it works fine. I have multiple family members that use it so I opted for a usb-C to 3.5mm cable for a wired connection. That way it's not connecting bluetooth to the last person's phone in the house. The cable setup works perfectly.

I bought this little amp to use in a stereo for my motorcycle. I am very impressed with performance, such sound out of such a small box. It is plenty loud and the sound quality is amazing and holds all the way up the volume dial. I have it playing thru some 3" full range paper cone sub woofers and am very happy. Great deal, hands down a good buy. There is some assembly but if you can fit the round peg thru the round hole you'll figure this out. I do recommend.

Small, Clean, Powerful for it's size and Bluetooth works Flawlessly, It is build really well and the heatsink is more than adequate... I seldom feel this but barely warm running at 4ohms per side load. Bluetooth has an enunciator that dings once. Controls feel good with an nice EQ sweep of bass and treble. Volume also has an on/off switch. I will probably use these in the future. This comes with pieces to make it adaptable for mounting in a case or use it stand alone. Back Connections are solid but the speaker wire size maxes out at about 16 guage or smaller...18.

This lil thing packs a punch!!! I needed it for my music studio for music engineering but what I had sucked. These actually gives the right clarity EXCEPT the mids are a little bit under so you ya e to compensate a little bit For the engineering side but other than that, sounds great! Songs already produced sounds fantastic of course out of the box. I’m using some 8” KRK’s with the high and mids. I’m sure if I replace the mid speaker with something better it would be all good. So grab one of these bad boys if you need something that is straight forward and ready to roll. I like this one and I want to get the bigger one too.By the way, the bluetooth on this is GREAT!!!!!

In a time of vast amount of radio communications happening all around us and more and more devices supporting Bluetooth is becoming a major problem for a product as poorly designed as this one. Not having a switch for Bluetooth on this amp is a major design oversight. I have this amp almost a year and almost daily am experiencing interruptions to the sound with Bluetooth disconnecting beeps are getting out of control. I live in a heavily populated apartment complex and many times I had people connecting to this amp! Not requiring a pass code for connection or a simple Bluetooth on/off switch is a major problem of this amp. Without a code or switch ANYONE can connect to this amp and broadcast on my speakers! The blame is partly on stupid people connecting to Bluetooth devices they don't know are theirs! Several times in the past year I got surprise connections to this amp and after a some time they disconnect after realizing that they are not getting sound out of the device they are trying to connect to. I am at a point where I want to desolder the Bluetooth chip from this device. I use this amp as a TV sound amplifier and hardly ever use Bluetooth. Sound quality and power is great but Bluetooth interference is horrible. So I'm sorry but the aggravations with this amp force me to rate it with 1 star!

I bought this unit as a backup if my home receiver ever went down. I read the reviews and that made my decision. Now I only have an old IBM power adapter with 16v 3.5 amps hooked to 2 Pioneer 150 watt towers. Boy, the sound is crystal clear and pushes the 12 inch woofers nicely. I had some distortion at 3/4 volume but attributed it to needing a bigger power supply. It gets crazy loud with that nice soft airy and punchy thump bass. Add an active subwoofer and you have yourself a nice system for cheap. The blue tooth hooked up nicely but didn't test distance yet. The only con is the blue tooth stays on even after turning off the amp with the volume control. I just bought this amp and it arrived the same day. Will keep updated.Update: one month of continual use 4 hours a day at higher volumes and still going strong. I replaced the power supply with a 24v 6 amp and hit uncomfortable volumes that didn't distort but rather sounded like the speakers were maxed out. This is now connected to the Bic America 15 inch woofer RTR towers and it sounds incredible. This just replaced my vintage Pioneer SA-1510 amp and tuner. Just ordered a second one for backup of this one, lol.Update: Purchased the Fosi Bt20a that has a nice case and build. These have more bass and the bluetooth has great range. I returned 2 of the Fosis as I thought I got a defective one. Whoever built these amps my hats off to you and thank you.Update again. Been over a year and all 4 amps I purchased are still punching hard. July 8. 2022 Update: April 3, 2024 and still rockin'
