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. 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. - Packing List: 1* G2 PRO Mono Power Amplifier, 1* 32V/5A Power Supply ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07TTMN51V | | Best Sellers Rank | #69,136 in Electronics ( See Top 100 in Electronics ) #182 in Home Audio Amplifiers | | Brand Name | Nobsound | | Customer Reviews | 4.3 4.3 out of 5 stars (202) | | Item Weight | 0.5 Kilograms | | Manufacturer | Nobsound | | Material Type | Aluminum | | Maximum Supply Voltage | 35 Volts | | Minimum Supply Voltage | 24 Volts (DC) | | Model | DZ072_UK | | Mounting Type | Freestanding | | Number of Channels | 1 | | Output Power | 300 Watts | | Package Type Name | [BO] Box Packaging | | Specification Met | FCC | | Supply Current | 5 Amps | | Voltage | 24 Volts (DC) | ## Product Details - **Manufacturer:** Nobsound - **Maximum supply voltage:** 35 Volts - **Minimum supply voltage:** 24 Volts (DC) - **Mounting type:** Freestanding - **Voltage:** 24 Volts (DC) ## Images ![Nobsound G2 PRO 300W HiFi Full Frequency /Subwoofer Mono Power Amplifier Digital Home Audio Amp, DZ072_UK, - Image 1](https://m.media-amazon.com/images/I/61ndrNsiHUL.jpg) ## 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 ### ⭐⭐⭐⭐⭐ Review *by D***S on 8 December 2019* First things first, this amplifier is tiny but it packs a hell of a punch.

I've had it more than a year without issues. ### ⭐⭐⭐⭐⭐ Review *by F***O on 25 December 2023* 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. ## Frequently Bought Together - Nobsound G2 PRO TPA3255 Hi-Fi 300W Subwoofer Power Amplifier Mono Channel Class D SUB Audio Amp - Dayton Audio BST-300EX, 300 Watts RMS,Tactile Bass Shaker, 4 Ohms Impedance - Turn Any Surface into a Speaker System - Generates Subwoofer Lows - FosPower Banana Plugs 12 Pairs / 24 pcs, Closed Screw 24K Gold Plated Speaker Plug Connectors for Speaker Wire, Wall Plate, Home Theater, Audio/Video Receiver, Amplifiers and Sound Systems --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/461004778-nobsound-g2-pro-300w-hifi-full-frequency-subwoofer-mono-power](https://www.desertcart.hr/products/461004778-nobsound-g2-pro-300w-hifi-full-frequency-subwoofer-mono-power) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-23*
