P.S. This is my first Instructable so sorry in advance for any spelling mistakes, bad pictures, or any thing else that I might have messed up on.
**Test Drive** Today i wore the backpack to school, everyone loved it. They thought it was store bought item and were amazed when i told them i made it myself (eventhough this is an extremly basic set-up). So build your own and impress all of your friends too.
Step 1: Materials
Speakers (of course, i used leftover speakers from a 70's era record player that was otherwise going to be tossed. Recycling!)
Medium gauge wire (just a couple feet will do)
Old 3.5 mm male audio jack (the kind you would find on a pair of headphones. Preferably you should leave 5-6 inches of wire on it or more.)
Amplifier (optional, makes the sound louder, duh)
5-6 inches of 4 inch PVC piping
~2 square feet of chicken wire
For Installing in Backpack
Wire stripping (Kleina tools make the best)
