Buddy, be glad im on your side.
Basically, they will fit. They might need a bit of assistance though.
Unless im mistaken, series one and two doors are identical. So what you need to do, is get a nibbler, dye grinder, or someone who has one to make the hole a tad bigger. The reason i went with my bostons (apart from the sound) is the fact that the speakers basket is made to help you get em in.. (Its as this as!)
Dont try and file it away either.... TRUST ME!
Any probs, PM me, or if worst comes to worst mate, Get my number off me, and we can talk it though.
