I have a wooden floor with wooden beading and then white skirting.

What's the best way to trail the wires?

BTW I'm getting the panasonic tower surround system.

I have the same system and a wooden floor.
When the floor was installed the fitters hid all the speaker cables under the beading, coming out in all four corners and in the rear centre for the bass (between the rear speakers) and front centre for the centre speaker, then all the speaker wires came up together behind the surround system.
Make sure they are all marked. I have now fixed the speakers on the wall.It must look ok, because my wife says so!!

Unfortunately my floor is down. Any more ideas? lol
