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.

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

Since this is a Mono Amplifier (one channel) allows for a little higher output due to the slightly larger heatsink used. With that said you still need to add thermal paste between the IC and Heatsink, then add a fan blowing air across this heatsink to get the full rated 100 Watts PEAK. not RMS!! I tested what the Max RMS output at 26 VDC, Adding Heatsink Compound between the IC and the heatsink and a high output fan and with all that I was just able to get just about 68 Watts RMS without clipping which is just over 96 Watts Peak. As received (as is) you will have NO Thermal Paste between the IC and the Heatsink which greatly reduces the output capacity of this Amplifier as well as having no fan. And with that you might get 25 Watts RMS if you are lucky. You have to make sure the Heatsink does not go above 90 C as that would up the IC die temperature very close to 150C which is the absolute max temperature for this IC to survive. It should shut down as it does have a thermal shut down mode that is suppose to save the IC but why risk it. Most Sellers will tell you what the actual IC Max Audio Wattage output it is rated to but not what the actual Amplifier Board can Produce. The size of the heatsink is very important. In this case BIGGER is BETTER. If you are going to push the amplifier over half of the rated power make sure you add thermal paste between the IC and the heatsink and have a fan blowing are across the Heatsink.

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.

Un excelente producto, tiene la potencia que el vendedor menciona, me encantó!!
