My question was about how the speaker level outputs are color coded. I want to make sure that the add-on sub feeds off the speaker level outputs that feed the factory bass drivers but i'm not sure which ones they are. does any one know or have schematic that show which cable coming out of the factory harness are which? I'd really appreciate any help with this.
By the way I transfered this directly from my E34 to my E38 when I upgraded to the bigger bimmer and it sounds awesome. It adds that extra umph that the premium sound package lacks so much. I'm redoing it just to make it neater and i wanted to do it myself coz I want to aware of the exact hookup in case i want to upgrade or remove it later.
