With the box it calls a notice in case you hesitate to connect one wire.
The connection is simple 1 RCA cable has connect to your home theater, and then the power cord.
There is a setting to adjust the bass power.
Viewpoint of quality, we will not lie that this is not the Bose or Jamo, but frankly for the price there is nothing to say.
This box will fit well and without problems sonorisera a room of 40 m2 max.
It is quite compact, so if you want a box without pretension but with a minimum of quality go for it !!
