i have recently installed a starcomm system on my bike and am at a loss as to where to put my mp3 player

i recon if i could get a pot of some sort with a lid, dont need to see inside once player turned on, but would need to be waterproof. i think something like that would be perfect was toying with getting a bib but if i can find a pot to fit there will be no need to have any wiring exposed, so ideas anyone ?
