Where to run speaker wires, From head unit to trunk... Options

[Ugglan]

Hi!
I'm going to put in an amp and a sub, and I'm planning to have them in the trunk.
This means that i have to run all my cables/wires from the head unit and the speakers from the front to the trunk. Where do i put them?
Should I run all the wires in the sides at the floor or should i run the speaker wires in the roof and the power wires in the floor sides?

How did you do it?
Which way is the best?

Yeah, that's a good idea, I have already tought about it and probably going to do it that way, just wanted some input.
Next question is where to run the radio antenna wire, should it go with the speakers, the powersupply (don't think so) or by itself somewhere...
