On a scale of 1 to 3, this project ranks a 2 in difficulty. You'll need to be able to solder, desolder, identify a few components and adapt this design to suit your application.
Total Cost
My out of pocket costs were $6. The plastic, speaker, zip ties, misc. wire were either found or leftovers from other projects.
Time
~1 hour once you have all supplies
Quality
From an appearance stand point - I give it a 9 out of 10
From a functionality stand point - I give it an 8 out of 10
From an audio stand point - I give it a 6 out of 10
From a loudness stand point - I give it a 7 out of 10
(A prior version of this would have had scores under 5)
As a side note - yes, this is technically not a stereo. Complaining about that is your prerogative, but I couldn't care less. If I say sharpie, you know it's a permanent marker - communication has been served.

Mounting Board
Specifically
*$5 Harbor Fright Megaphone
*Free speaker from discarded boombox
*Batteries, AA's are fine - they need to put out ~6V (I later used a 6V gel cell) - you can also use the original battery pack if that suits you
*Wire, some wire came from boombox - I also used a Cat5 cable
*Headphone jack can come from a pair of headphones
- For the mount, I used a piece of plastic that I then laser cut to fit perfectly into my bike rack - feel free to improvise, similar quality can be had using thin plywood and a jigsaw ;)

Check out my profile, one of the smaller images is a later bike stereo build using 2 speakers on either side inside of an enclosure.
Brings back such good memories!
Stereo version in the near future?
Eventually, I'll get around to sorting through pictures and documenting :p
Man... that looks so badass. Hooked up a generator for the battery yet?
How'd the awesome grant project turn out? Can cotton candy be launched great distances yet?
It's coming! I'm down to figuring out how the electronics have decided to destroy themselves over the winter, and turning a venturi tube out of teflon. I really really want to be done by Maker Faire Boston, which is in April!
Pics and more to come when I'm done :)
I might have to make my own
