I think you have to wire the Headunit to the Bose Amp in the trunk and the bose amp to the Sub Amp.....My friend has the bose system and explained to me how he did it but I cant remember right forsure...
well that, for the most part, is what i did.. maybe i'll tweak with it for awhile.. not in too much of a rush, decided i'll probably end up buying an aftermarket deck anyways
