Water bottle amplifier

i got a batterypack wired it up too a small speaker ducktaped it together with my i-pod shuffle
and boom now its attatched to the shoulder strap of my bag
its not that loud but its right my my ear on the left and i can still pretty much hear everything over my right

I've been trying to find a solution for this myself, problem being that my radio sits right where the optimum place for the speakers would go. I've been trying to work out other ways to attatch speakers to myself, I was thinking an Archie's Ninja type job on my belt with the speakers inside but I don't want the sound to be too muffled especially as part of the reason for wanting to do this is pedestrian early warning.
