04 porsche cayenne with bose

do these everyday........ use the factory mute wire, if there isnt one get a pin from the factory and tap into the factory wire harness(you can get them from porsche). the pin is located under the constant and i think to the right of the white amp turn on.(test first obviously). i always retap the fuse box for acc or ign also. there should be a some empty fuse panels. then use one of your outputs to just interupt the center channel.we use raytell not parrot.....my other shops use to use parrot. thats the easiest way without running to the amp etc. its fiber optic so if anyone tells you theres a harness interface there b/s ing you. if the car doesnt have a center channel and a little seperate speaker under the center channel grille theres plenty of room i alwasy put the speaker and the speaker for k40 radars under there no problem
