Super Easy Lego Speaker

I am a music person and have always been fascinated by the portable speakers I see here on Instructables. Unfortunately I'm not great with electronics, although I'd consider myself a master with all things structural, including Lego. This is an easy project for beginners or anyone with a bit of time to kill, since you only have to build a Lego box and splice two wires. This could also be a good hands on project for anyone who teaches about sound, circuits or electricity, especially since it gives the students something to bring home. This is my first instructable so go easy on me. I'd love any feedback or comments, but don't expect me to answer any tough electrical questions. I tried adding power to the circuit to increase volume but ultimately failed. Anyone who is willing to work through that, tinker away and tell me how it goes. Good Luck.

Step 1 Parts

For this project you will need:
Materials
-A speaker (mine was ripped from a nonworking one sitting on my desk)
-Headphone Jack (taken from speaker or crappy headphones)
-Assorted Lego pieces: a base the size of your speaker, about 2 or three layers of pieces, enough to cover, and a grate.
 (this is the simplest part of the project so use common sense, also every speaker will be sized differently so me listing won't even help)
- Source: iPod, computer etc (not messed up during project)

Tools
- Electrical tape or soldering iron
- Wire stripper or teeth or sand paper
