Let me use some harder numnbers. Lets assume the distances to my left front, center and right front are 25 feet 30 feet and 35 feet, respectively.

Should I cut them each to the minimum that they need, or should I make them all 35 feet?

Then for the surrounds, because I have to go around door frames, etc., I need one to be only 10 feet and the other to be 40 feet.

Should I make all 5 wires 40 feet? If not should I make the two surrounds 40 feet? Or should I cut them all to the length that is needed.

I am tempted to make the front speakers all 35 feet, but to cut the surrounds to 10 and 40 feet. This is mostly because I just barely have enough wire right now to do this. Plus I don't know what I would do with the extra wire going to one of the surrounds if it is 30 feet too long.

As a side question, is there any problem with running several sets of speaker wire along side of each other (so that they are touching) for part of the run?

Once again, thanks for all the help!
