Clyxgs TPA3116D2 Dual Channel Class D Digital Power Audio Amplifier Board, DC12-26V High Power Stereo AMP Module for Car Vehicle Computer Speaker DIY Home Theater Audio System

The first board I received worked but one of the two channels wasn't loud even after adjusting the gain. Contacted seller and they responded fast and sent out a replacement right away. The new board works as expected. Using this board to power two old 3-way speakers without any of my own crossovers. Nice middle of the road between too much bass and too much treble. Using the supplied cable (audio IN), I cut off one end and soldered on a 3.5mm female aux jack. Now I can either plug in with a cable or use a bluetooth TX/RX. Slight hissing when no sound is coming through but pretty clean sound once you get to jamming out. I will not think twice about ordering another one from this seller in the future.We are always quick to point out the negative so I want everyone that reads this to know that this seller was a joy to deal with. Thanks a bunch

This amp has a lot of power, but there is white noise on the output. It isn't really noticeable at louder volumes.

Very Powerful amp and for the price and size its worth every penny very simple and easy to use no led light indicator which would be nice but isn't necessarily needed I have it hooked up to 16v system and packs a punch and would definitely buy again when I'm ready for another project

Amp is very loud.Lots of hiss but I did the modification removing R3 and changed R4 to 5.6k.No more hizz.I feed this Amp with a dc-dc buck converter red board set @ 23.95V.I haven't being able to get the volume all the way up. but with around 20w playing Bass Patrol on my TV YouTube. the voltage don't even get near 23.50V.This is gonna be an upgrade to my Bass tube. I'm just waiting for my 22k mF capacitor to finish the project.

I did detailed testing using a Tecktronix scope and HP332 Distortion analyzer and 2 4 Ohm dummy loads. I started at 10w into 4 Ohms and tried to measure the distortion. My THD+Noise never got below 8% and was due to wide band switching noise. I was using an HP linear supply that was clean. I never did a 'Listen' test.

it's small, but powerful. it blew my speakers out the window! Clear sound and bass, no distortion. Great deal for a small price.

For $12 this is unbeatable. At 24 v it puts out 120 watts per channel, probably peak, not RMS and may be "Chinese watts" but it is powerful, well made and mates with the preamp, which you should buy with it.

This amp completely met and exceeded my expectations. Packs a potent 100 watts in a compact package. I like the fact that it has a large heat sink to dissipate heat. Fits well into my design and has proven to be reliable for my use. Will definitely buy again as the need arises.
