If you want to be running subs from your stock head unit, youll also need some sort of external subwoofer controller (http://www.thetechgeek.com/images/ne...os/PLXR-A8.jpg)... OBVIOUSLY do not get pyle (their garbage, just showing you what it loooks like). There are fairly cheap, and fairly nice looking decks out there that would have sub out put and AUX input for your ipod.
