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

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.

Works well with the shaker on my sim rig chair. I'm using with an xbox so TV audio -> amp --> to shaker.

If you want to bring some new life into your subwoofer

Good sound easy to use value for money

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.

This was a gift bought for me to power 2x JBL GT-5 subs. I am achieving 2 ohms which should give me 300w.... apparently. I can't even turn the volume on the amplifier to a third of the way without the amplifier turning itself off. There are also zero light indicators to say that this has happened. Just to note, the gain switches on the back are turned off (which still boosts apparently) and the frequency is turned right down, in Sub mode. I have to turn the amp off, turn the volume down, then turn it back on for the sound to work. This seems like a common problem as there are very similar reviews on the american amazon reviews of this product. Do not buy this. Looks like just another lying audio manufacturer!

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.

It works flawlessly. This little wonder box can easily push my 300w Morel sub driver (in a sealed box) without any issues. Perfect for my home audio solution. I'm running it with stock 32v/5a power supply. I'm keeping the gain settings to 36db (sw1 and sw2 'on' at the bottom plate). I don't have to go beyond 75% of the volume to reach room shaking punchy bass. Thank you Nobsound and Amazon.

i have a pair of older velodyne 12" powered subs - one of the plate amplifiers stopped working so instead of replacing the plate amp i tried this. it was simple to install and the sub sounds great again. i like that it has both sub and flat settings along with both a volume and filter range so you can tune it for your room or event better - musically it is great and you can add a depth that the subs did not seem to have before.

I am using this as a mono amp for a sub and it's exceeded my expectations. I've had it more than a year without issues.

muy buen producto

Connected with a pair of Audio Engine A2+ speakers and running a JBL soundbar sub - SW10, that I picked up super cheap. Bypassed the subs amp and using it as a passive sub. Works better than I expected and very easy and convenient set up. Adds an excellent sound to these little speakers that I have set up as PC and bluetooth speakers. And also very handy to be able have it on my desk so I can easily switch it off or control the sub volume.
