Install Subwoofer HELP
I cannot find any info on how to install a Subwoofer in the trunk of my CLS
I really need to know which wire i can tap into for the IGN remote wire for the SUB, and if the car has pre wiring for speakers on the rear shelf, if not what would be the best option without having to take the beauty apart!!

NOTE - the car has the stock Audio 50 option - all guides and wiring diagrams would be mucho appreciated !!
