JL audio makes custom sub boxes for the Titan I beleive. Your CD changer is most likely not to have preouts. I suggest getting an adapter of some sort that will make it have preouts (I dont know what its called). I have a new Sentra SE and I LOOOVE the radio on it (I have the audio fanactic package). The one 8 hits pretty hard for a stock system. It even makes the license plate rattle.
I just suggest getting a custom box from www.jlaudio.com or get a thunderform MTX box.
