Bose 3 speaker, speaker add on
 

how do I add rear speakers to a bose stereo, which color wires in the harness are the speakers, for the stereo? I want to splice my rear speaker wire to the front ones

i can probably help but, what car is this in? is it the factory harness? why don't you just splice the wire closer to the front speaker instead of up by the harness that way you know which colors are going to which speaker. or if you want to do it from the harness look at the speaker location to see what color the wires are then splice them where you want. i hope that makes since

I figured it out, there is writing on wires on harness.
