Volume requires weight, unfortunately, although beating physics is a noble pursuit.
I probably have everything you need in terms of materials, so does Alex.
I own several of the little class D amps in the linked instructibles but regret the purchase as the resultant sound is not up to my standards.
I don't think you're going to be happy with =any= computer speakers, sorry.
For small, light and good sound, I'd set some small bookshelf speakers, a pair of 7 amp-hour sealed lead acid batteries in parallel, and a small car amplifier as the minimum equipment.
I'm also in posession of a pair or two of 2-way boxes that I think you'd like (they are faily flat and could ride like panniers).
Ammo, do you have a particular bike that you would like to set up?
Have you seen this set-up? Seems to get great reviews... and be loud enough.
Just to inform everyone. This is not for just me. This is geared toward group rides, like Mass and my bike club rides. Trust me, it is safe.
Jim said:Hello Ammo, I had another I idea since you mentioned group rides like Mass and such. Up here in Kenosha we have a bike club called Handlebars and Bars. We go around riding bikes and drinking usual on Fridays or Saturdays when it it nice out. The one member has a trike that is chopped down and has some good sized ape hangers like you have. He modifed a grocercy basket on the back to make a decent sound system. He used a Bosch power box and some other goodies. The power box is not that cheap but can be found at places like Lowes or Home Depot. It has decent noise out put and you can run a mp3 and CD's on it. As for your chopper, get a back cargo rack and mount some saddle bags. Put the speakers in the saddle bags and on top, build your componets on the rack. This will be a good winter project until mother nature quits been such a bitch. As for getting a ticket by the cops for noise, the city has bigger problems like people shooting each other and crooked public officals.

If you do have a decent rear rack on that thing I have some already-made rack systems that aren't getting used, no need to support Home Depot . . .
but I think your original desire was to build something =in= to the chopper?
This be the bike you want to put it on?
Ammo said:hahah yes

Tough one. About the only safe option I can think of is to see if a "shelf" can be installed hanging out beyond the back of the seat that can hold a med-small system.
