It comes in pieces so you'll have to assemble it. There's no instruction but take a look at some photos and you will figure it out pretty easily. I use it with my 3ohm speakers and at 9V it distorts a bit. I ended up using 5V and everything is alright. I can still hear a bit of hissing but seems like there's nothing to worry about.

I wasn't aware that the product requires assembly when it arrives. However, that said, it is a simple process to assemble it, and it's well worth the effort as this amplifier delivers high quality audio. I would reommend this product.
