disconnect power lines, the bose has 4 wires to a speaker cabinet, 2 fatter ones and 2 thinner ones, the thinner ones are audio signals and bigger ones are power, simply just disconnect power leads and match the wire color codes - + at the headunit to the speaker location. I did not rewire my car this way worked fine for the last 4 years i had this. btw i woundnt suggest using stock bose speakers with aftermarket stereo as the BOSE has 0.8ohm speakers specifically designed for bose internal amps and aftermarkets can only handle 4-8ohms so this might cause problems to the head units because low impedance and may overheating to headunit internal amp.
