well i have a ford escort lx 1997 and the mounting depth is like 1 7/8 inch and it seams like a pain to mod the door becuase of window handle to drop in a pioneer rev 6.5. i was going to go with a coaxile because of no space for a tweeter. but i was thinking if i build boxes for the speakers and put them down near where your feet go and aim. would that work if so how big show box be? and should it be sealed? if i went with comps would the tweeter be able to be in the same box? any ideas be nice thanks
