6.5 inch will fit with no problem. If you want the easy way out, you can more or less fit the speaker onto the original plastic riser, after you cut out the old speaker from it.
The better way is to use a MDF riser that is bolted to the door, then the new speaker attached to that.
I had a 7.25" speaker in my B15 when I had it, fit behind the stock upholstery like normal.
