Review: 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.
Review: 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.

## Features

- Dual-Purpose PBTL/SUB Switch: Versatile operation allows the G2 PRO to function as either a full-frequency amplifier or a subwoofer amplifier. A dedicated SUB output is specially designed for active subwoofers, with compatibility for both passive and active subwoofers. Additionally, two G2 PRO units can be utilized to independently drive left and right channels, minimizing channel interference.
- High-Power Output Capability: Equipped with a TPA3255D2 amp chip and a robust 32V/5A power supply, the G2 PRO delivers up to 300W, easily driving passive speakers or subwoofers with up to 320W power. It harmonizes well with a variety of speakers, including outdoor, bookshelf, computer, desktop, ceiling, and floor-standing models.
- Premium Design and HiFi Sound Quality: The G2 PRO features a gain switch for two levels of output level adjustment (32/36 dB) and SUB frequency tuning (40-300Hz). It includes a built-in speaker protection circuit and a low-pass filter to ensure noise-free audio even at high power output. Both SUB signal and amp outputs are available simultaneously for an enhanced HiFi listening experience.
- Compact Size with Elegant Aesthetics: This mini-sized, mono integrated class D amplifier boasts a compact design with powerful functionality. The durable, solid aluminum chassis is both fashionable and built to last, making it an ideal choice for HiFi home and desktop audio systems.

## 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
