The Fosi M04 Subwoofer Amplifier was purchased as part of a computer speaker system in which the original amplifier "died of old age." The speakers were still good so it made no sense to dispose of them. Since it is not being used in a home theater system, I cannot speak to the full 100 watt output capability. My original computer speaker system (Logitech) is a 5.1 system with the amp inside the subwoofer box. I purchased a six channel amp for the surround speakers and this Fosi 04 amp for the subwoofer. All works well together. Listening to pipe organ music, which can put out some big bass sounds, the amp provides the bass that I need. (I do have a good audio system for music.Amazon has the "frequently returned" warning for this item. That's probably because people order without understanding what they need, not because the product is inferior. It produces lows from 20Hz. The item was packaged very well with foam and an attractive box, with a factory seal. I would place this in the excellent category of quality and price. (It's not junk) and has an 18 month warranty. Of course I have decades of experience building electronic devices and knew what I wanted for the purpose and budget

Got this subwoofer amp to bypass the amp component of my active subwoofer which died months ago due to a peak in voltage. My amp was those that work in "stand-by" mode, so they are always powered up somehow. Replacing the board with a new one (original) was too expensive, even more expensive than what the sub costed me in the first place, so in order to not throw the box and the woofer cone to the trash, I decided to just rewire things up in order to bypass the sub's integrated amp, so I got this GREAT little FOSI amp to power my "now passive" sub.Things worked great and my sub is now back to life, shining again.The M04 Fosi Amp is a great choice as it is POWERFUL, noiseless (at least to my ear), very small and does not generate any important heat. It comes with a power adapter, so you only need the cables to connect the input signal and the output signal to the passive subwoofer. I used the convenient "bare wire connection" to hook the modified sub to the speaker output of the Fosi Amp. Worked NICELY.Quality of the M04 Fosi AMP is VERY GOOD, in a very neat, compact and ellegant BLACK enclosure. It is definitely worth the money, which is NOT AT ALL expensive, but quality exceeds by far the amount paid for this amp.Until now, i'm really loving it.

It works well with a passive sub-woofer and with the cut-off frequency adjusted right it compliments the sound of the rest of the system (high-end speakers which just lack deep bass).

Increíble , se me daño un subwofer Infinity PS-12 (200w) y pensé qué tal vez solo tal vez este equipo podría darme un poco de potencia para usarlo como bocina normal , sorprendentemente puede excitarlo de forma completa , muy impresionante !!!
