the wires you need to tap into run off the factory amp.BUT the factory amp does NOT have enough power to turn on an aftermarket amp! I would recommend this install be professionally done because you need to add a switch activated remote turn on lead,and you also need the correct line level adapter to plug in so the bass levels will adjust accordingly,I recommend the In-Q adapter made by MTX,I think.It will plug in and also give 3 sets of RCA outs and and Ipod plug to charge and play your Ipod with the factory Bose.

in the past, BOSE units in GM's (thinking mid 90's camaro's here) had a line level out put (more or less) out of the deck, and each speaker had it's own "optimized" (read: cheap) amp located on each speaker.
that may be the problem, very low level out of the OEM deck, and impedance mis-match could cause the bass to distort. OR, the adapter could just take out the BOSE mid-bass hump.
i read on another where a guy wired it off his fog lights, and that way he can control the power, pretty slick, a amp only needs a 12v signal to turn on, no load. i think i would just wire it off the accessory output somewhere.
anyone got a pic of hte Bose subbox in the console?
