Hey.. if you are looking at getting the 6.5s I've got a set of
these
speaker adapters that I would be willing to sell you. I mocked them up when I was doing my install but went with my custom mounts instead my speakers were just a little bit smaller so the holes didn't line up just right . I don't know about the Infinity series or how the depth would be...
The only thing I didn't test with them and might be a problem is that they r about an inch and a half thick all the way around and may bring the speaker out to much to get the door panel on.. But I'll sell them to you cheap just PM me or send an email
