A few months back I asked about installing a sub in a '03 Monte Carlo SS with factory radio, this never went down but I think I had it all figured out how to do it. I just bought a '00 Grand Prix GTP, it has the Bose in it which I have no problems with, but I want to install a sub keeping the factory radio. Can I just hook it up like the Monte with a LOC taping into the rear speakers or does Bose change this.
