Audio Wires Near Power Wires

[Blu-Benny]

so i'm wiring my HT right now and i've got the wire for my fronts & mids in.

i also have to run a power cable in wall up behind the plasma.

how should i go about doing this so i don't lose any quality in the audio cables?? i'm gonna come close to 2 or 3 outlets while i'm running the speaker wires.

in this picture, the blue box is representing where i plan on putting the outlets for the audio equipment and ps3. the speaker wire goes right over the top.....how much of a problem is that going to be.....if any. the power cable is going in between the same studs as the blue box as well.

i'm gonna run the power cables about 3-4" below the speaker wire and wire the box from the bottom.
