I have read hundreds of different installtion material and it always says that you should run the RCAs on the opposite side of the power/remote cables, because it can create distortion.
I have also been told this by many people, including professional installation shops.
Now, I have never not done that before, so it may not effect anything, does it matter?....
I've been running mine on the same side and there is only a TINY bit of speaker wine that comes with it. You cant hear it if you turn the volume more than 5% of the way.
I re-wired my system the other day though and now its whining like crazy so I'll tell you what was wrong with it when I fix it today.
