Review: Amazing bit of kit, great sound. Real powerfull. Fully reccomend - I have already bought one of these Bluetooth amps with the 2x220w speaker and 1x350w subwoofer outputs. Just on the off chance that I could wire up a couple of my Dewalt batteries and use up an old sub and speakers to make a boombox. I was so blown away by how loud and good the sound was I had to build another a bit smaller and portable so I could use it more, so I went for this 2x50w speaker and 100w sub output with 1 battery at 18v. This was the outcome in the video. Once again well powerfull and amazing sound.
Review: Great little amp - Great little amp soun quality is spot on Loud ran a 10" sub 300 watts and 2 50watt speakers perfect

### ⭐⭐⭐⭐ Sounds great to me!
*by M***T on 21 July 2025*

I read a lot of the reviews and didn't have great expectations at this price point, but this thing rocks, very pleasantly surprised how good it seems to be. Got it all connected an old sub and pair of old car speaks, nice ones and it's sound! Simply, does just what it's supposed to and very loudly if you.crank it up. Let hope it stays working. Ah, no annoying pairing voices :-)
