So you can give me your SOUND advice in this regard. My idea was to buy Car Speakers and then hook them somehow to my PC by placing a 3.5mm Jack at the end of the wires. (Please dont ask me how...as I dont have any idea about this....it is just an idea).. Also one question came to my mind about the power source. In cars it uses the Car battery but How would I supply the power to the speakers from home. thats another problem.

So now my idea is to buy 2 ceiling speakers (65QR) each and an Amplifier to hook the speakers into. What amplifier will suit this idea. Can you recommend me some amplifiers?
