I built my boombag in a courier bag.

I suggest getting a bag dedicated as a boombag either and old good condition bag, or find one at a thrift store.

Tools needed: Circular saw, Jig saw, Drill w/bits & screwdriver bit, and x-acto knife

measure out the bag, and build a plywood box that fits within the bag, with an opening at the top.

use "piano hinge" that you can pick up at any hardware store, and cut a piece of plywood for the top and screw together.

For a power source I went back and forth on but thought the best way for me was to use a small jump box I picked up at pep boys for $30. I like the jump box because it has a 12v outlet (cigarette lighter style) and it's rechargeable. Make sure it will fit in your plywood box!

For a speaker I used a 3-way 6x9 and a external preamp. You can also use powered computer speakers w/bass and a 12v/110v converter.

Figure out how it will position around your power source, and cut out hole, and drill access holes for power source (for charging plug, and 12v access)

Put in bag and cut hole in bag for speaker (make hole is a bit smaller than speaker)
Screw speaker through bag fabric into wood box.

Mount the amp on the side of the bag. This is needed to ventilate the amp and it gives me access to the volume control on the amp.

I use an amp I picked up off of ebay for $12.99 (S&H INCLUDED) Can't beat that!

I like it because it allows me to adjust the volume, bass and treble.

It's pretty basic about 100w - 40w output. You could go bigger 500w - 75w output but your battery life will suffer.

On a full charge I can get a good 5 hours at max volume.

The whole thing ran me like $75 and was fun and easy to build once you have all the components. It's also not the lightest thing in the world about 15lbs. (mainly the jump box weight) but I like having it on my back vs on the bike, it gives me more control of the bike. I also don't have to take it on and off the bike and can use it indoors as well.
