Passive sub install, speaker wiring question.
Hi Guys, i have recently installed a powered amp and sub in my Rover 75, Wifey loved the sound so much she wants same in her X5 e53, i have a passive sub to install but i cant work out where the speaker wires are in the boot area, any one here can give me a heads up on which is left n right wiring for speakers in the boot
i have been asking this question on various sites and got not one answer, am starting to think BMW drivers dont really venture into the wiring of their cars


Thanks
