Nobsound G2 PRO 300W Subwoofer Amplifier, Mini Mono Channel Class D Integrated Sub Amp, Full-Frequency and Bass Switchable Home Theater Audio Amplifier for Passive Speakers/Active Subwoofer

Good sound easy to use value for money

First things first, this amplifier is tiny but it packs a hell of a punch. With it being no larger than a medium sized hand, you'd never think it'd be able to handle a subwoofer with as little as 2ohms without distorting or overheating. It surely can though.I received this amplifier as a gift, to be used with my passive bose subwoofer. It provides more than enough power at half volume and allows me to adjust the crossover which is perfect. The amplifiers frequency response is also very impressive, it is able to get produce very low bass without distorting or clipping. I also like the fact this can be used as a crossover with powered subwoofers too.I would definately recommend this amplifier. Utterly amazing for the price, it's compact, has great sound quality and looks stylish. Perfect for anyone looking to buy an amp to use with a powerful passive sub or adjust the crossover on an active sub, that's lacking crossover frequency controls.

If you want to bring some new life into your subwoofer

Low frequency Large Sun-Bass driver in mono application. I bought two units for stereo pair of speakers, extremely satisfied.

I'm super impressed with this little, (it's tiny), power amplifier. It's loud. I listen to techno so I can't say for sure how good the quality is, (my speakers are a bit basic too), but I can't really hear any problems. It's the same as my indoor HiFi - this is in the garage. And it's fine. Loud.. And sooo small.

Absolutely blown away by this little amp. I'm using it to run a 1.2kw Eminence 18" sub and it shakes the house to bits.

I'm actually quite impressed I'm using it to power a 250w subwooferWitch it has no problem for just over 12 months with moderate use.Then this morning I turned on the amp to hear a pop the subwoofer input no longer works fortunately this import is the same as the left right audio jack so the device is still usablethis does lead me to believe that the quality of this item is not as I first thought and as it is now over a year old I cannot claim for the failureJust as a small point as well it claims to be a 300 watt amplifier but the power supply provided cannot supply 300 Watts of power it's a 32 volt 5 amp power supply volts x amps = watts equalling 160w power supplyMy advice would be to look for something better but in the class d mono amp world there is little to choose from

Very impressive little amp, been using it to power a 2ohm 300w rms alpine car subwoofer indoors and it can almost get it to as loud as the car amp.I mainly chose it because it has a subwoofer switch which most other indoor amps don't have. This single amp was the cheapest way of doing this without buying an extra full size amp and an extra crossover for my sub.It is very neat looking and a nice finish but the power supply box is huge. If these two were combined it would be almost the size of a normal amp so kind of cheating on the size front! But you can tuck the power supply box behind and then just the small amp is on show. For me size isn't much of an issue and this small one was obviously hard to stack things on hahaMy main gripe is along the lines of the other reviews I've read in that it cuts out when at full power, presumably going into protect mode, with no warning whatsoever and can go unnoticed if you are busy and the other speakers remaining have some bass. I just turn it off and on again and it comes back on and I lower the dial until it stops cutting out. It's never particularly hot or sounds bad, seems like it could keep playing normally. Would be nice to have a clip light or protect light or some way of knowing whats wrong. I've never turned the gain switches as it can't sustain full power as it is.I have since upgraded to a second hand yamaha p7000 amplifier which is so powerful but absolutely huge and heavy to power my new 4ohm 1000w rms sub so quite a lot more bass now!The nobsound (great name btw) is perfect for powering my smaller 100w rms pair of indoor speakers at home on full frequencies and handles full volume with ease.Overall pleased with it and it got me through several months of heavy use djing (although sometimes cutting out) and is now very well suited at home. Price is also reasonable!
