my room is under renovation and I'd like to hide all the wires of my hi-fi set under the floor. I have to choose cable to connect laptops out with amps aux in - it would be over 6 meters long. Would microphone cable be suitable? Due to it is stereo and has shield better than in one I can buy i local electronics store. I'd like to get rid of all the fuzz getting from the air by not shielded wires.
