Many thanks** A: No, there is a single RCA input, and a single Aux 3.5mm Jack Mono socket. You would need to connect it to a Mono subwoofer output on your TV or Hifi. **Q: Can I add this to an exsisting amp to provide my system with a sub? Bit knew to this but any guidance would be gret. Thanks** A: Hi, as long as your amplifier has a subwoofer signal output it will work. If you split the signal before the amplifier then the volume will be set and won't increase/decrease with the volume of the music. Most AVR amplifiers have a sub out but a dedicated amplifier usually will not. Hope that helps. **Q: how many amps is the power supply?** A: Hi it comes with a detachable 19V Power Supply. But I ordered the Nobsound 24V power supply from Amazon UK. So I could get the maximum amount of watts from the amplifier. Plus I used my own higher quality better performing figure 8 UK plug instead of the Douk Audio supplied one. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good Value Produt. *by D***Y on 9 June 2025* In 1 word-EXELLENT. ### ⭐⭐⭐⭐ Nice little amp! *by C***S on 2 November 2021* I bought this amp as it is a mono amp and all I want it for is to drive an old AV system centre speaker with a Chromecast Audio connected to it. I am pleased with the amp as it sounds good and it has also got a 'bass mode' switch that allows it to be used with a passive subwoofer. ### ⭐⭐⭐⭐⭐ It comes with a power supply *by A***R on 26 June 2024* Looking around amazon you some devices like this that don't come with a power supply. When you add the cost of the recommended one, the price becomes much greater than this device. It wasn't clear to my mind that this item would be any different. I took the chance and when the small box arrived I thought I may have lost the gamble. Opening the box however revealed a nice power supply with a UK plug that can deliver 19V to the amp. The amp itself is a lovely bit of kit for the money. If you want a single channel amp that you don't need to blow your ear drums, it will do the job. Nice to be able to use it in full range mode or sub woofer mode. In my case I have it connected to the subwoofer signal level output of a home cinema amp in full range mode connected to a passive sub woofer. This way, the amp can manage the signal filtering rather than having to fight the amp filtering. Works a treat. Hope it lasts. ## Frequently Bought Together - Douk Audio G4 Mini Subwoofer Amplifier, 100W Subwoofer&Full-Frequency Mono Channel Digital Power Amplifier - electrosmart 10m Red/Black 2x 1mm 2x 89 Strand Speaker Cable Wire for Home HiFi/Car Audio etc - Goaycer 4mm Banana Plugs - 24K Gold Plated Bannan Plug Speaker Connectors 6 Pairs / 12 pcs --- ## 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.it/products/174949519-douk-audio-g4-mini-subwoofer-amplifier-100w-subwoofer-and-full](https://www.desertcart.it/products/174949519-douk-audio-g4-mini-subwoofer-amplifier-100w-subwoofer-and-full) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-11*
