Ok, so the car is on the way, but lets face it, bass is necessary. The stock speakers are going to be replaced Rockford Fosgate Punch all around, as well as some nice dual 12\" Punch woofers (I like bass with presence, not volume). Anyway, until a decent replacement is available, the stock head unit will do. The OEM integration looks great. So, continuing on, Im going to take a wild guess that the stock HU has no subwoofer preout. That being said, for those of you who have added a bass box to your car, how and where did you hook it up, where is your audio feed coming from?
