If you are wiring the extension cabinet in series:
Speaker 1 + (positive) should go the the 1/4" Phone plug's TIP (hot)
Speaker 1 - (negative)should go to Speaker 2 +
Speaker 2 - (negative) should go to the 1/4" Phone plug's RING (ground)
If you shorted the connections on the plug OR you have an open speaker OR you have a defective or corroded extension jack in your amp then there will be no output.
Try disconnecting the internal speakers (power off) and connect the extension cabinet to the main output (which is currently working by itself, I assume).
If the extension cab works fine when connected to the main output jack, then the problem is likely to be in your amp at the extension jack. If the cab doesn't work then you have a speaker or wiring problem in the cabinet.
