Did you use the 3/4" ones in the front or the rear? The white ones were 3/4" and should have gone in the rear. If they fit in the front, that is news to me- past XV owners reported that only 1/2" adapters cleared the door panel in the front so I had been fabricating based on that assumption.I installed my speakers today. It was interesting to say the least.
I used Infinity Ref 2 way speakers on the fronts and Pioneers 3 way speakers on the back.
Problems (But Nothing Drastic)
Yes the fronts went in OK. Spacers fitted. I added some sound deadening inside the door and around the speakers.
The rears are where I had problems. The spacers didn't fit. In fact, my Aussie XV rear doors look different to slanidracula's rear doors - odd. So I installed the Pioneers without the spacers.

The opaque-white ones were for the front, but I can't tell from the pictures where those were mounted.
Thanks for the pen-and-ink endorsement on the front of the adapters!
