5.0 out of 5 stars This is a great little amplifier for a subwoofer!
Reviewed in the United States on 14 December 2017
This little amplifier met my needs perfectly. When my old Onkyo surround-sound amplifier died, I had to replace it with a new one. The old one drove the subwoofer directly, but the new one requires a powered subwoofer. A powered subwoofer can be pricey, so I looked for a better way, and this is it. I DO wish that more detailed data on connections and specifications was presented, but it's not really needed. It is not clear to me if a 12-volt power supply will support the full 100W output or if a higher voltage 24-volt?) is needed. In any case, at 12-volts, output seems adequate for my system. The unit is very easy to hook up.
The little green block has the (+) and (-) speaker terminals, which are perfect for a single subwoofer like most systems have. The input takes a 1/8 inch stereo microphone-type plug: very easy to connect if you have a connector cable with that and connector(s) to match the AV amplifier output. In my case, the amp had two phono plugs (R and L), and I had the perfect pigtail to connect it all.
It would tidy, and not that difficult, to mount this small unit inside the subwoofer box, but then I would have had to fish a long coaxial audio cable through an under-floor conduit, so I went the easier route and mounted this amplifier near my AV amp, using my existing heavy-gauge speaker wires to run out to the subwoofer.
Power is supplied by a laptop power supply; it plugged right in. It's rated at 5 amps, and it seems OK.
The knob turns a volume-control potentiometer with an on-off switch. A red LED is illuminated when the power is on.
A low-pass filter is clearly incorporated; regardless of input, only bass is passed through to the speaker. There seems to be no way to adjust the crossover frequency.
So I am very happy! I will update this review if any issues crop up.

5.0 out of 5 stars Surprisingly powerful when following recommened specs
Reviewed in the United States on 24 December 2018
Shown in pictures: the small wooden case I've fabricated around the board.
This device is powering a passive 12" DIY subwoofer using a 24V/3.0A power supply, and is more than strong enough for that membrane. As stated, the board has a built-in low pass filter, which doesn't hurt (I have another 80hz low pass filter in the subwoofer).
In these types of class-D chips it is very important to provide the maximum rated power in order to avoid nasty-sounding distortion at high volume. Please read carefully the specs sheet from TI, those are very well written.
