Looks like it was installed at the factory
2006 Jeep Liberty
Crutchfield Customer Review (What's this?)
Needed a way to mount a radio in my Jeep which has limited dash space. This proved to be the best, cleanest and most professional method. Clear, custom instructions, looks like it was installed on the assembly line.
Pros: Perfect fit, well made. Price is the same as ordering it from the manufacturer, but they charge an arm and a leg for shipping. No shipping charge when ordering it from Crutchfield. Thanks!
Cons: Kind of pricey, but they've cornered the market, so...
