I went with the Boston Pro's, they have better highs which I think were worth it; full sound range is good even at 80+ mph. I did amp them via an Alpine amp (kept the stock stereo, didn't want to loose the left hand controls).

Now, I have to figure out a new amp solution so I can amp Lucid's rear speakers

NOTE: I didn't get a 4-way amp because it was too big to fit under the drivers seat, nor a sub; both because I want to keep all my trunk space I can. I'm going to create a custom bracket tomorrow to mount the Alphine CD changer over the gas tank, let everyone know how it goes

Boston Pros (w/tweeters mounted internal), alpine amp, Alpine 6 disc changer, and installation for $1K.

 

If you got the $$$ why not?
