Loudspeaker in Arcade Stick Box

Hello, i wanted to ask, if someone here in the community ever put speakers in there arcade stick?
If yes, then where, how, which source for it(audio from a console, or an MP3-player?) and how does it sound? Also which Material is your arcade stick made from?
I am not a music/sound- techician, but i want to put Nintendo-DS Speakers in my arcade stick, but iam not sure where and how does it sounds. And then i want to put audio from my pc/mp3-player & xbox360 in there with cables and connector.

Thanks for all answers
