Step 1: The Materials
You're going to need
1. An audio cord ($2)
2. A 1/2" (or 1/4") to 3/4" jack adapter (<$1)
3. Some sort of cheap amp ($15 from wal-mart)
Total= A little less than $18
I've heard the Audio Cord called different things so just describe it to the guy at radio shack and he can help you find it
The adapter size depends on the jack on the audio cord. If you have a 1/2" jack on the audio cord, you'll want a 1/2" jack adapter. I've got a 1/4" jack on the cord and my 1/2" jack still worked after a little wiggling and some tape.
