Look where the plug goes in
There will be a C shape with a dot in the middle. Follow the line attached to the dot and you will see a + or - which is the polarity. Next you need to know Voltage. Look in the same area, or on the label for this info. If there is NO info by the power plug, it might be AC, which has no polarity - just plug it in. The label may have this information and will say something like 12VDC or 12VAC that is the key. DC Matters (+ and -) AC does not.

SOURCE: JBL Media 100 Speaker power?
Buy a power adapter from radio shack or similar place. You need a 1000mA 12 volt dapter. Just make sure it is rated @ or above 1000mA to avoid the adapter heating up and possibly burning. The whole setup is rated @ 850mA wich 1A(1000mA) should handle with enough head room. But it might run you about $15-20. I would just buy a cheap radio with rca inputs/aux input and use that. I got one from Walmart for around $40 and it plays CD's & AM/FM.

I fixed a similar problem I was having. It requires a little work.
Take out the four screws from under the broken speaker. Carefully remove the cover, separating the speaker from the base. The two are wired together so don't pull them apart with force. Then remove the single screw, which is much larger the the previous four, and separate the speaker from the top cover.
If you chose you can remove the wires from the speaker, they just snap on, but its not required.
What I found is the speaker issue is not with the wire or the power, but the speaker it's self. On the back there is a big round metal piece. On my speaker that piece was pushed towards the front of the speaker. When I looked at the good speaker, that big piece was all the way back. So I simply pulled it back and presto, instant fix!
I hope this works for you.

I have JBL Media 3 Speakers running on the factory supplied power supply and the label states: JBL POWER SUPPLY, Model No. DV-9319B, Input: 120VAC 60Hz 35W, Output: 13.8VDC 1.7A, UL Listed3T58, E148325, CSA LR99152, Power Connection Diagram shows, Ring: Negative, Tip: Positive, CAUTION: INDOOR USE ONLY
PERSONAL NOTE: The power supply DOES NOT have the AC plug on the back. It is big hefty black block with an attached AC cord on one side and an attached DC cord on the other. My speakers are mounted high on the wall and run at approx.90% of full volume with Bass & Treble set flat. Actual volume and EQ settings are controlled via the sound card software based "Mixer Panel".
