Bought a bunch!
I installed a surround sound (7.2) system when I renovated my family room. I need 1 each for my in-wall subs and then got 2 more to power 4 “shakers” that I installed on my couch. They’re awesome little amps. Clear sound, plenty of “oomph,” and don’t get too hot. They are perfect for my subs and shakers. I recommend.

Un pequeño-gran amplificador
En mi caso lo uso para una televisión en modo full range, gran volumen (con una sola bocina coaxial de 4 ohms), poco consumo y poco espacio requerido, eso sí conectado a un regulador de voltaje. Gran precio también.

Great little amp
Bought this to replace the buttkicker gamer 2 amps that is 16x larger. This little amp works so well and has less delay between Rumble and press time also much more defined Rumble. Great little sub amp for buttkicker.

Great little subwoofer AMP
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.
