MSGEQ7 not reacting to Audio

Grumpy_Mike:
Bad idea on three counts.

  1. You are shorting two outputs together, expect to damage the audio source.
  2. You need a capacitor between pin 5 and the audio input.
  3. You are not making a good connection like that, connections need to be soldered.

I don't think you mean that the common ground is connected to the signals but that is how it reads.

Alright, so I'll be using the audio jack from the RadioShack. My question before I try that is, there are two prongs and then the big metal backing that the audio jack clips into.

Which is left, right, and common?

I'm sorry if this sounds simple, I've been confused and haven't been able to find an answer if the metal back is negative or not.

[EDIT]
FYI, I didn't connect all three to one individual wire. My apologies for the confusing explanation. Each one was connected to an individual wire that I placed on the breadboard. I'm switching to the audio jack because you were correct that they provide better connections.
