For such a small amp, it sure packs a big punch! I have an 8 speaker setup in my backyard, but the bass was lacking due to all the speakers being outside. I then bought a 300 watt outdoor subwoofer on Amazon, but I still needed an amp to drive it. In my search I came across this little Fosi amp. I figured if it wasn’t good enough, I’d use it to drive one of my indoor 150 watt subwoofers whose amp no longer worked. Needless to say I was quite impressed with the power output. So impressed, that I bought a second Fosi to drive my broken indoor sub. Now both of my subs are working great and sounding good. And compared to the $350 price tag to buy a replacement plate amp for my box sub, this was well worth the savings. The only caveat is that there is no auto-on feature like most box subs have. I have to manually switch the unit on & off every time I use it. But for the savings, it’s a small price to pay. Maybe in the future, Fosi could add this feature to their power switch: offer an on, off and auto mode. That would make this little but powerful amp perfect.

This little ripper replaced a home-built subwoofer theatre amplifier that kept our movies “thumping” for over 20 years. It weighed about 4 kg with a massive torroid coil transformer feeding the amplifier push-pull circuit. No matter what hubby did, he could not get rid of the low frequency hum when no input signal was coming in from the Yamaha theatre receiver sub output. Apart from that, it thumped the passive subwoofer speaker for two decades.We decided we needed a replacement for “old hummer”and chose this unit. It arrived and I was a little taken aback - it is 1/4 the size of the previous amp. I wasn’t sure what to expect.Needless to say, I need not have worried. This little unit packs a massive punch into the 8 inch, 6 Ohm subwoofer speaker and when there is no input, it is as quiet as a church mouse. Bye bye humming...We have to have the FOSI set at about 1/3 to 1/2 volume otherwise the sub overpowers the rest of the theatre sound and starts rattling our French doors leading into the theatre room.I get that it is new and you can never be assured of the longevity, but the quality from the outside looks and feels good and the output at a low volume setting is simply amazing - despite its miniature size. Clear and concise. And no idle hum. :-) Long may it stay this way!

I am impressed. I just build a DIY subwoofer for my home theater. Had to build a specialty box because it had to fit between the back of my couch and the wall. Only had about 5-6" to work with. So, I had to build my own. Obviously I couldn't install an amplifier in such a shallow box, so I bought this thinking it was worth the try. I AM IMPRESSED. I did a great job on the subwoofer. While not very deep, it is large in length and height. I connected this amplifier externally, and I have to admit.... I am totally impressed. So clean and quiet (until music/movies are playing). Highly recommend it. If you have a subwoofer with a burned out amplifier, DON'T THROW IT AWAY. Just open it up, disconnect the speaker wires from the internal amplifier, extend the speaker wires outside of the cabinet, velcro this amp onto the existing subwoofer and connect the wires. Perfect repair. Now; if you are trying to replace a 400-1000 watt amplifier, well this is only 220 watts. But seriously..... unless you're in a car with a little weenie complex, do you really need more than 220 watts. Anyway; for the NORMAL person, this is a great amplifier for a DIY subwoofer build or to save you old subwoofer that has a broken amp.
