🎵 HiLetgo TPA3116D2 2 x 50W 2.1 Channel Digital Audio Power 100W Amplifier AMP Subwoofer: Enhanced Audio Performance for Immersive Sound Experience Review

2.1ch with subwoofer works well for listening to music loud enough for home use. I'm playing music from a mobile phone connected to two 10" PA speakers with an 8" subwoofer. It works loud enough in Crystal Sound. Good product with a good price. buy more.

Well that was the first amplifier board I bought that didn't work. I have never bought a Hiletgo product. And I'm sure mine is just bad, but all it does is pulse like there's power pulsing through it. I'm not going to scold the whole company like some do, there are flaws everywhere. Maybe the next one will get to the point

So the sound amplifier works as it should, but you have to know that there were no instructions with it and the circuit board is printed in Chinese. Luckily another person posted here which exits are which. If you know how to connect it, it works fine. Documentation would be helpful, but for the cheap price you get what you get.

Works. It is save. However, the sound is a bit dull. It's great for a homemade craft board. Creating a home entertainment speaker system for HI-FI sound, for example, I would refuse. Don't get me wrong, it works. I use it now with some exciters. But I don't feel like it has the settings or performance it claims. For the money it's great. 3.8 stars is my real rating. TO BUY OR NOT. lol

Edit review 7-25-20. After a few months of use I switched to using only the AUX output and these photos are the result after 3 weeks of not connecting any speakers to the stereo outputs. to solder 3 coils, one was not connected at all. As far as performance goes, it's not even remotely accurate. I have a 100w 50X2 board that beats this one but I wanted 2.1 for the sub and it works for what I have. Despite the fact that each component sits askew on the board. If you want to mount it to or…

Subwoofer support sets this amp apart from others I've tested. Extending the dynamic range is really important. Don't expect this to rattle windows, it doesn't, but it does add lower range as a subwoofer should. I can't measure the power output so I can't say it meets the advertised specs, but it's loud enough for a normal sized room. I can barely hear any white noise near the speaker at full volume with no input. I am satisfied with the sound quality. On the other hand, the output coils get…

So I bought this board to fix my Klipsh ProMedia BT 2.1 speakers. The control unit seemed a bit broken, but Klipsch wanted about $60 + tax + shipping for it. For example 1/3 the original cost of the speakers even though they knew they had problems with amp burn-in and all. Damned. So I figured they were dead anyway, I could try some cheap drugs just for fun. Got this amp, hooked it up and brought the speakers back to life. I also took the extra step of cutting it into the back plate after…
