I plan to put a new Blaupunkt radio in my 1969 911S. Besides the speaker wires, there is a black wire, a green wire, and a wire that is yellow with red stripes. Can anyone tell me what each wire is for, whether I need a seperate amplfier, and where in my car the speaker is located (its not in the dash)? Thanks.
