"The media could not be loaded. 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."

Apart from having to put it together myself (not difficult). Sound is absolutely amazing, especially considering the price and how tiny it is. I am using it to power speakers in my back yard. The speakers were from an old surround sound system.jack kinge

What can I say.. it was exactly what I was looking for, definitely good value for money.I have it in the shed and feel like the power output may be too much hahah.Power supply 24vThe amp is powering 2 small satellite speakers and one 12inch car subwoofer at 4ohm I had lying around lol. And it powers everything very good sound quality. with the connectivity of BT 5 on-board makes everything easier.ant
