I agree with Tyson.
Way back in the early 1990s I had my first surround system. I had a dedicated 2-channel amp for the back speakers. I decided it would be really cool to have that amp closer to the rear speakers, so I moved it from the front to the back and extended my interconnects. Now granted, the interconnects weren't fancy or high end but my god, the noise they picked up - I couldn't believe it. And it wasn't subtle. They were noisy with no music playing and any music was so distorted... I moved my amp back immediately. I learned a good lesson if nothing else.
