Nobsound 100W Subwoofer Amplifier, Mono Channel Digital Power Amplifier Audio Mini Amp

This is a great little amp. I bought the full Freq version and a 24v 6amp power supply, have stereo Bluetooth as an input which is summed to a mono output by the amp. Output (banana plugs required) goes to two outdoor Yamaha wall mounted speakers wired in parallel (halves the speakers ohms) to give mono music (ideal for outside) all around the patio. Very powerful, very little, very impressed. Would buy a second one for another project in a heartbeat.

Brilliant little bit of kit for the price. Only reason for 4 stars was the audio jack’s ground was not soldered on. But it was a quick fix and performance is as expected. It’s a shame the input requires a 3.5mm “headphone” jack as opposed to the usual RCA connector, but converters are numerous and cheap.

Amazing and powerful small device, exactly what I was needing for my setup. The NS-03G-FR takes the 3.5mm aux input stereo signal and combines/sums both sides into a mono RCA output. Perfect if you want to use just 1 single full range speaker. Quite difficult to find a power supply with the right connector that fits, this way, I would recommend to purchase the power supply together.

I brought this as a mini amp to power my sub woofers to give them a boost but I plugged everything in it made a noise then went quiet I turned it off then on again and it just made a constant buzz noise and everytime I plug my music in to play it won't play and the buss noise won't shut up I know I plugged it in right as I've been using music items for about 4 years and I've had many amplifiers and never had 1 do this to me, I'm sorry about leaving a bad review it's not my choice if you want to buy this or not maybe I had a faulty one but I'm quiet annoyed it doesn't work

Wanted to add some bass to my car without going overboard .. this works perfectly.I used this with an aux splitter running from my phone, plugged it into my cars aux port and to the amp with a 160watt rms sub.The sound quality is great! It provides deep bass and is very loud even when only powered by the 12v cigarette lighter socket.So far very impressed!!

Product failed 15/07/24 which is only 8 months after purchase. Return not possible so I assume this is a standard thing. Buy cheap, buy twice.Edit. I eventually got in contact with nobsound as it was bothering me. They were actually very good, and agreed to meet my pretty much half way for a replacement. The new one has been pumping away for a good few months now without issue. I hope it was just a one off problem with the first one, because it does actually work very well, and blends perfectly along side the stereo nobsound amp I have powering my speakers. Fingers crossed 🤞

This is a reasonably competent module and importantly... it works. It should be pointed out that you need a DC power supply. Nobsound do one which is inexpensive or you may consider using a Buck inverter with either a battery pack or a DC power supply in excess of what the Nobsound module uses.In my situation I made a portable Om-nidirectional speaker with down firing subwoofer which this module powers well.

Just what I wanted, a mono full frequency amplifier. Great little product. Volume is very sensitive, slight touch to adjust volume. I have an external stereo to mono convertor to 3.5mm as wasn't sure whether the amplifier summed the L/R.I have noticed the Nobsound G2 which has L/R phono inputs so presume that does do it. I may swap it for that one.
