Super price performance, ideal for small systems

I bought the system because I have an office where I would like to hear a little music (radio).
As I have already "lying around" a lot of speakers still of old equipment that seemed to me the best solution, rather than buying a whole system.

Technology:
12V 2A makes a maximum of 24 watts input power, with losses I would say that the part can output 15 watts. That sounds a little, but for normal room volume is the absolutely sufficient (and saves electricity)).
What I noticed is, the wiring of RCA inputs and the speaker is distorted, that is "Left" goes on "Right" and vice versa. Sure, cable and turn finished, but a little embarrassing, I think that's, well, well, the price makes up something like this ...

Acoustics / Sound:
I tested both small no-name boxing and Devil VT 11. Now are there any tips boxes, but probably the "biggest" what you connect to it. The sound is absolutely okay, noise can only be heard at full volume, and is holding up rather well in the frame. It is not comparable with a 7.1 power amplifier, but for my purposes (office or possibly even in the garden) perfectly adequate. Tower speaker I've tried absolutely not because in my view, the output power of this is just too small to really because what "rauszuholen".

Conclusion:
Anyone looking for a small stage and still has a few speakers, can safely access. A star there is deduction for the processing and the above-mentioned "mistakes" in the wiring. Handy for the garden, office or similar right. It can also operate over a car's cigarette lighter.
Should be forgotten but not that you have to buy a power supply separately! Not that one then wonders how it since joined;)
