Second time we used Crutchfield.
Both times we had to search for non-Crutchfield YouTube videos on installation. It would have been tougher without doing that.
Window tinter, auto glass installer and DIY auto radio install YouTubes helped with disassembly of dashboards and door panels without damaging parts. Crutchfield has a few videos but they are incomplete and don't offer tips nor cautions.
Crutchfield included instructions were "remove from package, assemble, install."
So we had to call for assistance as well.
The Crutchfield phone assistance was helpful and friendly. A bit confusing, but we figured it out together. Have a computer with email handy when you call.
