A lot of Class D amps (and some others) are bridged, so there is no ground side per se. Also, the Speakon connectors and the cables themselves aren't shielded.
A metal box will work fine too, as long as you don't tie the box electrically to the speaker leads. Plastic is a lot easier to machine though, and lighter.
If you have a rack mounted amp, a back panel for the rack with punch-outs is an easy solution as well.
