🔊 DAMGOO TPA3116 HiFi Dual-Channel Stereo Audio Amplifier Subwoofer Digital Amplifier Board, DC10-25V, 100W+100W Output, Steel Volume Adjustment Knob Review

Generates a lot of power without using a lot of power. It only heats with constant full power. The sound quality is excellent. Delivers true rated power at maximum input voltage.

This thing works great. It's nice and loud. I used it in my truck and attached a table to it. The only thing wrong here is reading labels for connections. If the labels were on the back I would give 5 stars.

Terminals too small for 14AWG speaker wire. It also has a very faint high pitched beep. I've used this for ceiling speakers and put a smart switch in the end to turn it off when not in use so I don't hear background noise.

It really works like an amplifier. I didn't take exact measurements, but I can say that I hooked it up to two 6" Alpine SPJ-161C2 coaxial car speakers at just 5V with almost no effort. I hooked it up to 12V in my car. There is one, though Constant high pitched squeaking that sounds like some kind of feedback I tested with 3 different power supplies (laptop USB, USB charger and fused 12V) and all power supplies make the same squeaking It's definitely a component issue.

This is a great little amp with a lot more power than I expected. I use it to drive some 8" ceiling speakers at 100 watts RMS. I opted for a slightly larger amp to make sure they weren't underpowered. In the end, I almost didn't have to turn on the amp to get the speaker volume as loud as possible, or at least a volume that anyone would ever want to hear. No noticeable distortion, loads of power, great value for money. I will definitely buy another one in the future, even if it will probably…
