The models with seat speakers, as you know, have an upgraded Bose surround system. I reckon you can run the wires from the seat speakers to one of the existing speaker lines, but it won't perform properly because your radio doesn't have the surround amplifier and soundstage capability. It will just add extra sound form the seats at similar volume to the rest of the speakers at best. Those with DVD capability use the player inside the center console. If your car has no player in the console, you don't have DVD capability. That's not to say you should pass on having bourbon seats in better condition! Those are rare and you might want to buy them just to have them.
