Recently I purchased some Alpine Type R 6.5 inch components for the front and Alpine 5.25 inch Type R for the back and also I got the appropriate spacers from ia performance. When i tried to install the speakers it seemed that there was no way that they would fit. Especially the back speaker. So I was wondering if I was doing something wrong or if maybe they just don't fit at all. Is it possible to get them in there without extensive modification. I need help quick because if they don't fit then I have to return them within 14 days. Please Help!
