I decided to do the door card insert job yesterday, as I've been putting it off for far too long. Whilst off I tried fitting one of my Alpine speakers, straight off there are an additional two end mounts although in the way could easily be bent, the actual four mounts are elongated for ease of lining up I suppose but they foul against the door card. Dremel came out, made a couple of slots adjacent to the top mounts. Now the speaker just fits in the cut-out but the oem grill didn't want to go back on. Put the original speakers and grills for now and have been looking at Compatible speakers for a 2002 Spider (#16) for maybe a round speaker install.
