Anyone added a subwoofer to a 2004 330i with Nav ?
I have almost finished and just need to wire up my line-level to RCA adapter and need +- for LR/RR and auxiliary on/off, from behind the left trunk panel, where the car's amp/DVD/receiver is.
I need the wiring diagrams for the stereo and components, anyone know where I can get it ?
There is some outfit out there that is called the Mileage Man, and the concept is the same. Anyone used the Mileage Man's system or have the diagrams ? http://www.mileageman.com/pages/AddAmp.htm
