You will need to hook up the subs through an aftermarket amp. You can buy a converter box that basicly converts 1 left and 1 right speaker wire into 1 left and 1 right rca outputs...wich then you could run to your amp. Since the stock head unit does not have a l+r rca's on it this is the only way i now how to do it. Maybe some one else has a better more profesional way
