## Questions & Answers

**Q: The amplifier comes with a 32v/5a power supply (160w) yet you claim a max power output of 300w; how do you produce more power out than is supplied?**
A: Someone answered here saying you can run a 48V power supply for more output.  Well yes you will get more output OF SMOKE! These units cannot withstand 48V power supply as the capacitors are only rated for 35V max and 35V max is clearly marked on the amplifier!   I measured 20V RMS clean sine wave driving a 2ohm load - that is about 200 watts RMS continuous... when they say 300 watts, that is some peak (instantaneous) rating but not continuous.  I got that measurement running the amp with the included 32V power supply.

**Q: It works for a 12" 450rms car subwoofer with dual 4 Ohms?**
A: Yes

**Q: Cómo conertarlo**
A: Supongo que hay varias maneras.. en mi caso lo hice desde la salida subwoofer preout de mi Amplificador (canal .1) al audio in del aparato. Luego las salidas deben ir conectadas con los cables del subwoofer que me quedaron cuando retire del parlante el amplificador dañado

**Q: Do i need a crossover for the passive subwoofer if i connect it to amp’s speaker output? is the sub cutoff of amp only pertains to sub output only?**
A: The low pass cross over knob only works for the speaker high level output and does not control the low level sub out

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great little wonder
*by  on Reviewed in India 10 September 2026*

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.

### ⭐⭐⭐⭐⭐ Amazing! Cannot believe the power!
*by  on Reviewed in the United Kingdom 8 December 2019*

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.

### ⭐⭐⭐⭐⭐ 300W class D multi amp - its good.
*by  on Reviewed in Canada 25 February 2026*

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.
