100W TPA3116D2 Amplifier Full Frequency Mono Channel Digital Power Amp Board NE5532 OPAMP 8-25V (Mono, Board)

This 100W amplifier board worked perfectly! I bought it to use in the speaker I was building and let me tell you, this board made everything super easy. For the speaker wires it uses a simple screw-down mechanism so you don't need to solder anything! This gave my speaker a lot of power, even just running off my phone, and it can get LOUD. It has a 3.5mm audio jack built right in as well, making the board very easy to hook up to any device you are using. I definitely recommend and will look into grabbing more from them when I decide to build more speakers.

I used this to power my passive sub as my amp didn't have an amplified output. Works great I used an old laptop power supply to power it and 3D printed a case for it. Only issue is it is building up static electricity for some reason and discharges when I go to adjust it. Also even when switched off the power light is dimly lit.

The details state that the power port is 5.5mm by 2.1mm. I ordered a 5.5mm by 2.1mm cable and it doesn't fit. I'm a little upset, and it would be nice if there was some support on this. I shouldn't have to buy their power supply only to cut off the plug end

The sound is very bad. Very sharp sort of static sounding. Tried it with 2 different speakers, 2 different inputs, 19v power adapter and 20.5v of batteries. I would return it but I missed the return window.

I powered a 160 watt light bulb without the amp breaking. So it defiantly gives its rated power. Sound quality seems good.So I have no complaint's especially with such a good price tag
