from what audio out to what?
I ran good quality speaker wire in the wall from a second floor bedroom computer to my stereo audio receiver directly below in the living room. (about 15-20 feet). I soldered rca connectors and tried it out. The result was very low volume with significant noise. A local home theater installer told me that I should not have used speaker cable as it is not shielded. Is that correct or do I have some other problem?
