Ok.. that idea is definitely out, thanks guys. Will just 6-1/2" and Tweeters up front be enough? I really don't like the idea of any highs coming from the rear, that's why I was just going to put a 6-1/2" woofers back there.

What do you think of a Boston Acoustics Pro 6-1/2" Component set up front and 2 12" Subs in the hatch? Should I have rear fill? What would I use?
