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.

If you open the case, you can change the Jumper shown by red arrow, to swap between the two, make sure unit is disconnected from power before you change jumper. Circuit is labelled for jumper. The full frequency amp is on definitely on the bright side of sound, sub doesn't seam to have a high enough low pass filter, it could do with going over 150 to 250 hz for more usability 👍 Recommend for full frequency mono to a crossover, or cinema sub, not music sub. Highly recommend 👍

Omg what a great little amp and powerful run my subs sweet and hard defo recommend to anyone Small compact and packs a punch but u will need a good power supply I use 24v 5ah kicks like mad 😎

Powered my main ADX tactile bass shaker + other shakers perfectly. Immediate delivery. Low cost, adequate quality. Could use an isolated on/off button.

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

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.

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 🤞

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.
