Connect 3.5mm Jack to a Speaker Answered

Hello, I am trying to connect a 3.5mm jack to a speaker I salvaged from an old radio. The speaker has 2 wires: A + wire (marked yellow) A - wire (marked black) The problem is, the 3.5mm jack has 4 different wires: on one side, there is a copper one and a red one on the other, there is a copper one and a blue one. I got the speaker to work for a few seconds while plugged into my phone, but I cannot remember how it went.

Think about it man - where did you get the jack, and what did you hack it off / hack off of it?
