I've got an 05 with the Bose system and have a few questions about changing speakers. I've been reading on here a little and pretty much have more questions now than I did to begin with. I'd like to get a little more bass but I don't need 2 15's and a 1000 watt amp or anything. Can you swap speakers with the Bose system and have it work alright? Also I keep hearing about this car having factory subwoofers but are they buried in the trunk somewhere or are the speakers in the rear deck considered the subwoofers? So basically I'd like to know if I can just swap the door speakers and possible the subwoofers wherever they might be.
