This amp is tiny, and works great for my use case! I am using this in the garage with some old bookshelf speakers, its plenty loud for me and sounds just fine. If you are looking to blast out the neighbors, this little amp probably isn't for you, but a small potentially portable or non-heavy use, seems to do well. Used a old 19V 2.19A hp laptop brick for it. Package includes the board, nice little laser cut backing and top protective plates, a few screws and standoffs, and a tiny screwdriver to assemble with, as well as descent instructions. The quality of this is better then I expected for $12, took a chance and it paid off, not a bad little amp.

I bought one of these and connected it to two surround sound speakers. The sound quality was really good for the small speakers that I had it connected to. This unit is vesatile in that it has inputs for Bluetooth,USB drive, and Aux In. It also has a nice remote that allows full control of the unit including an EQ button. It can be run on various power supplies anywhere between 12 and 24 volts dc. It is so small that it fits just about anywhere so uses for it are endless. i recommend this product.

Used to power two Kicker KS 6-1/2 coaxials in a Cessna 210 diy project. Speaker wire terminals are a little flimsy but the volume knob is very solid and the Bluetooth works well once it’s set up. Sound is superb for an $11 amp, clearer than most cars if you install speakers properly. Also plays very loud if you need it. Would skip for a permanent amp, but works wonders in a diy application. (Running a 24V power supply)
