The opening isn't a standard double DIN size so yeah the mounting kit is needed.
As you can see from the photos I posted there are substantial areas at the top and bottom the kit covers that would otherwise be gaps.
This is a photo of my first single-DIN head deck without the dash kit.

As you can see there are big gaps all around it. Whilst driving I could see straight through to the wiring at the back.
Also be aware the Alpine I've got doesn't have any sort of CD/DVD drive in it. It only plays video from iPod and music from iPod or USB...
