Can any of you give me the size of the door speakers? Also, has anyone changed out the dash tweeters - any thoughts on how to get at these without destroying the dash? Also - stupid question but are the dash tweeters something that is purchased separately or do they come as a set with the door speakers??

I am planning to replace my '05 stock system this weekend (or at least get the process started) so any info is appreciated! I plan to post detailed step-by-step and pics of progress. So far the only piece I have pinned down is the Pioneer AVIC-D1 nav/head unit.
