Does the non-premium model sedan (2005) have the wiring for the Bose system in place? It would seem to me they would have one harness for all the cars with the Bose amp wiring for the premiums and also the non-amp wiring for the non-premiums. Can anyone confirm/deny, or do you know where I could look for the harness in the trunk? Will the existing speaker wires work as well?

Thanks in advance to anyone who can shed some light on this for me. If this won't work, I will probably end up throwing in some Alpine Type-R's with a 500watt Alpine amp (I've already got a nice Alpine 9855 head unit from my old car) but Alpine stuff is _expensive_ ^_^!
