I have an '04 Sedan with Premium package, with bose, naturally. As has been said before, the sound aint too great. I get better sound out of my Harmon/Kardon soundsticks on my Powermac G5. I am looking to put a bass tube in my trunk. I wasnt looking to spend over 200. I was wondering what the most painless way to do this would be. I understand that bose has propriatary equiptment, but I have heard it has been done. If anybody could help, that would be great. If you could tell me what is needed, how hard it would be, and just point me in the right direction, thanks a lot
