Just wanting to keep factory bose speakers and head unit installed, but add a better sub with separate amplification. I already have the power wire ran and have a hi/lo convertor for the RC's, but need to know which and what wires to tap into at the bose amp location, in order to get the proper signal to the new subwoofer? I am working with a 2004 Nissan Murano SL with bose stereo without the navigation system. Please Help!! I don't want to go and start nipping into the wrong wires.
Also, how difficult is it to tie into the existing rear AC output for my remote wire? any suggestions?
