wiring for rear speakers in parcel shelf

[Ade]

Im converting mine so that it has speakers in the parcel shelf (originally it just had the 2 front speakers) but want to know where I should lay the speaker wires.

Any suggestions for retro-fitting the wires from stereo to rear of car? Where do BMW hide them?

Pull the carpet up and sling them under it, BMW run all the cables in the bodyframe up each side of the car on the inside of the sill, can't remeber how hard it was to get the car stripped to that point. Piccy for you so you can see where they are.
