How would i remove an aftermarket radio in a 2001 ford ranger?

I'm giving my girlfriend a sub for her birthday and i can't figure out how to get her head unit out. Here is a video link to show you the kind of radio she has.

Only difference is that her radio is a kenwood.

If you want to give your girlfriend head, you're asking in the wrong category.

There are 2 little holes left and right on that radio, those are made to stick in clamps to push the hooks aside and remove the radio, there are special removal-kits for that.
