Haha, if you think BOSE makes the best speakers ever, you got a lot of reading up to do. Check out any car audio website and they will tell you how big of a waste BOSE is. Also, get a set of BOSE speakers and a set of any set like Diamond Audio, CDT Audio, or even Pioneer are you'll be amazed at how crappy the BOSE sounds in comparison. Sure they are better than some crappy Autobahn or Lanzar speakers, but for the money you can get a set nice way nicer speakers.
Its easy to find 3" tweets and stuff you just gotta look for them. Id recomend Pioneer,Rockford fosgate,alpine.
I was probably just going to get a set of CDT Audio CL-61A-25 PROs. I've been wanting them for two years now but I've never had enough money, so I have to save up.
