Nobsound G2 PRO 300W HiFi Full Frequency /Subwoofer Mono Power Amplifier Digital Home Audio Amp, DZ072_UK,

The amp on my B&W ASW300 decided to kick the bucket, so gutted it and wired it as a passive, and after plugging the Nobsound G2 Pro, I'm back in action. I set it to use the max gain with the dip switches on the bottom. I adjusted my levels to the desired sound output and well that's it. The thing sounds real loud and had it running for four hours straight with loud bass, heavy music just to put it through the paces and did not disappoint. The unit doesn't even get more than barely warm. Highly recommended for anybody wanting to power a passive sub.

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.

Good sound easy to use value for money

I bought this to power my Logitech Z2200 Subwoofer as the original controller for the plate amplifier was acting flaky. So I opened the subwoofer up and cut the wires to the Plate amplifier from the subwoofer. I installed binding posts in the back of the housing and ran the subwoofer wires to them. I ran the amp to the binding post. The Z2200 has an 8 inch long throw subwoofer in it. I used this amp to power it. It is overkill but it works great! The sub has never sounded better! Plenty of overhead. Very happy with the results. This amp has plenty of power for a bigger subwoofer! Easy to setup. It does not have Auto on and off. You have to flip the switch. Not a big deal in my situation but it might be for others. I am using a Fosi DA2120C and this amp for the subwoofer out. It is easy to set the gain and volume to match the speakers output. So you only have to set it to how much bass you want in your system. Works great!

Nuevamente menciono que no soy un profecional del audio. Este amplificador lo adquiri para alimentar un subwoofer pasivo polk (el cual me quedo del Polk Magnifi Mini. De este subwoofer, se daño su tarjeta electrónica, por cierto de muy mala calidad y la barra de sonido, todavia sirve pero se calienta muchisimo). Este amplificador es muy sencillo de usar y cumple muy bien con lo que necesitaba. Se calienta un poco, de igual manera lo conecto a un regulador de voltaje para que dure muchos años. Llego en buen estado y tres dias antes de lo programado.
