It breathed new life into the sub, and works great now. It completed our 5.1 surround system. Plenty of power - just make sure you have a power adapter that'll work with it. The power cord that I had on hand is a bit underpowered, but gives us plenty of bass. Review: Great little and powerful woofer amp - NOTE: This is for woofer speakers that are not amplified and where your main amp does not provide an amplified woofer channel. This amp is doing a great job with the woofer of my sound system! The clarity is awesome and the volume is more than we need for our room! The pricing was very affordable. A couple of things for buyers: This amp requires a separate power supply - the list clearly says this but, of course, I missed that. You can use your own power supply, but since this vendor has a cheap power supply that works, I ordered it and it was there the next day - great service! Easy to setup the amp and power supply (took like 2 minutes) and the bass sound is outstanding! For tech geeks only: the instructions and the website have one MINOR spec contradiction: The amp supports woofer speakers that are as low as 2 ohms and as high as 8 ohms of impedance. The instruction page that comes in the box says it only supports 4 ohms to 8 ohms of impedance, not 2. I talked to the firm and 2 ohms is the correct spec ## Features - NS-03G is a sub power amplifier for passive subwoofer.

RCA? 3.5?** A: 3.5. I run rca into a 3.5 from my radio **Q: Power on/off creates a loud annoying pop. I would like to shut the output with a capacitor to suppress the pop. What capacitor value and voltage?** A: I was very concerned with the very loud pop and found the only solution was to use: https://www.amazon.com/gp/product/B097T2YNB4/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&th=1 I use this as the speaker cable and before shutting off the amplifier, I flip the switch on the speaker cable, disconnecting the speaker from the amp. It works perfectly. **Q: will this work with an input from a preamp?** A: Not sure. I used input from a receiver and that worked. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Finally, some bass! *by L***A on September 24, 2025* Been looking around to power my unpowered sub woofer that I picked up for cheap at a thrift store.

I am satisfied with it and will keep it. It stays cool at high volumes (8-ohm load). However, here's a few points: (1) The info card states a Terminating Impedance: of 4-8 ohm load.. I think you should disregard the 2 ohm in Amazon spec. (2) They state the terminators are for Banana plugs, but you can connect bare wire by unscrewing the terminals to reveal holes in the posts that can accommodate up to 14 gauge wire. (3) Don't expect good sound anywhere close to 100w with the recommended power supply. (4) An 8-ohm load will sound good up to about 25 watts with the ported enclosure I have - plenty loud for a large room. Your mileage may vary. I have shared the 'manual' in the photo section. Hope this helps... ## Frequently Bought Together - Nobsound 100W Subwoofer Digital Power Amplifier Audio Mini Amp (Black) - Nobsound DC 19V 4.74A 90W Power Supply Power Adapter Charger Universal 100-240V 50/60Hz AC Input for Amplifier Laptop DAC - RCA to 3.5mm Mono, 6ft 3.5mm 1/8 inch Mono Male Plug to RCA Male Audio Cable Adapter, for Speakers, Subwoofer --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sc/products/45551265-nobsound-100w-subwoofer-digital-power-amplifier-audio-mini-amp-black](https://www.desertcart.sc/products/45551265-nobsound-100w-subwoofer-digital-power-amplifier-audio-mini-amp-black) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-04-23*
