Depends whether you've got a 3 or 5 door ibiza. I replaced the original speakers in my
3dr mk4 and had to end up using VW Lupo speaker adapters and adjust them slightly. I think i bought the ones that you're looking at first off and found that they didn't fit at all. When i did it a couple of years ago they didn't make 3dr mk4 speaker adapters but they may now. Hope this helps.

I've got the 3 door, looking to fit this weekend so need to get the right ones if i can
 
Yeah they look right! They didn't make these when i was doing my speaker fit thats why i had to use Lupo ones
 
Sorry to sound like an absolute ICE amateur but what speakers are you looking at to use with these adapters? Is the size much different from the standard (i.e. a straight size swap isn't worth it) and will the standard Alana head unit have enough power for them?
 
I can't remember myself but I used this pic for a reference (to see which ones were red and black)
