Speaker cable route to rear of touring?

[Spion]

I need to route new cables from my head unit to the rear of my touring. What's the best way to route them?

[oze30]

under the trans tunnel or factory way-down the drivers side sill.

im about to do this, am going under the carpet down the center. i tried down the side but the cables were so chunky, nothing fitted properly, so out come the seats

[fowler]

go down the centre chapm as its the easiest route

[guizai]

where do the cables go once they reach where the centre channel meets the seat shelf? I had a heck of a time trying to see if cabling will fit through there.

I just fit chunky rear speaker cables and a disk changer lead in the drivers side sill no problems.
