Only one of the five outputs on the subwoofer to the cube speakers appears to be working. I've tested all of the speakers by plugging into the one functioning output and they all work fine. Any help is appreciated.

Re: Subwoofer outputs not functioning
Have a good look at your set up in regards to volume output to each channels .
you may have only one channel working due to volume turn down or a faulty connection from the console head unit .
After going through all these , i would suggest to get your sub amp checked as you may have a faulty amp .

Definitely need more info - such as type of amplifier or receiver, how many speakers you are running, whether the subwoofer is powered or not.
As a simple test procedure: Disconnect all speakers and plug in a pair of headphones. Get a strong audio signal? Good, move on. No signal or week signal, you have an amplifier issue before the audio even gets to the speakers.
Next: Disconnect all speakers, turn the volume down, and connect one speaker to the left output channel. Slowly increase the volume. If that works, do the same on the right channel. Everything OK? You're putting out enough gain on both channels. Sometimes one channel goes bad. You can still listen to your sound in mono moder, or drive two speakers from the single working output. Not stereo, but dual mono. Move on.
Connect left and right speakers but not the subwoofer. Repeat the test. Whatever is left is probably the problem. If the subwoofer is powered, check the power supply or incoming voltage. If the other speakers are driven off the subwoofer or powered from there, that's likely the problem.
try to trace your problem inside the main circuitry of the jacks ( open it and see on the solder side of the Printed circuit board(where all the electronic components and soldered/welded if there are loose connections (small cracks... use magnifying glass if you have one) then solder them. also check for the transistor amplifiers and output capacitors.... check also for the connectivity of all wirings!
Check each Subwoofer or Speaker that isn’t working for continuity - At the subwoofer or speaker, one at a time, test the terminals for Continuity using your Digital Multi-Meter; if your DMM doesn't have a Continuity test, use the Resistance, or Ohms, test and check for Resistance in the Subwoofer Coil (be sure to disconnect the subwoofer wiring before performing these tests).
If they test out good, hook the wires back up and test the terminals at the terminal cup or at the Amp hookup if you didn’t use a terminal, don't hook it up to the amp yet. Sometimes the wiring inside the box can be a problem if it has come loose, or isn't making a great connection.
Make sure there are no Hi-Pass filters, crossovers, or multi Channel switches enabled.
Replace your RCA cable/s with known working RCA cable/s from the Source/Head Unit to the Amplifier/s.
Check your Head Unit settings; make sure the Bass is turned up and/or the Subwoofer setting is turned On.
If you are still getting no output, try plugging in an MP3 player or CD player using a headphone to RCA adaptor and check for sound output. If there is still no output, your Amplifier outputs are probably burned out.
The Jamo speakers need an AV Receiver to drive them properly. The TV doesn't have the correct outputs nor does it have the power required.
The Jamo kit consists of a powered subwoofer ans 5 small surround speakers. Each surround speaker needs to be powered by the speaker output from an an AV Receiver. The subwoofer should also be connected to the receiver, but the connection is a phono/RCA lead from the receiver's "Sub Out" socket.
Your TV connects to the AV receiver via the Optical out.
To connect powered speakers and/or subwoofers follow the instructions on page 19. Connect the powered speakers from the Main L and Main R.outputs
"MAIN (STEREO) jack: The stereo (MAIN L,R) bus signal which has passed through the MAIN MASTER control and graphic equalizer."
for the subwoofers set the YAMAHA SPEAKER PROCESSING switch on/off for best sound as desribed on page 13.
To test this I would play the song Let's Go by Calvin Harris.
for best results use a matched pair of speakers and subwoofers
such as the Electro Voice Live ELX112/ELX115 to the elx118p subwoofer.
Either the subwoofer speaker or its amplifier failed - they couldn't handle the extended use. Simple test to find out which: put the volume really low, connect another subwoofer (or a large normal speaker) to the bass output on the receiver and play some music. If you get sound then the original subwoofer is faulty, just get a new one. If you don't get sound then the amplifier for the subwoofer channel has failed. You could replace it yourself if you have enough electronics repair experience, otherwise it will be cheaper to just get another good sh low end receiver from a site like Ebay.
Depending on the model, there are two ways to connect a subwoofer to an amplifier, receiver or processor. The best way is to connect the subwoofer to the SUB OUT or LFE output of a receiver, but some subwoofers can be connected to the speaker level outputs of the receiver or amplifier.
1. How to Connect a Subwoofer to the Subwoofer Output
The preferred method of connecting a subwoofer is through the LFE or Subwoofer output (SUB OUT) of a receiver. Almost all home theater receivers (or processors) and some stereo receivers have a subwoofer output. The LFE (Low Frequency Effects) is a special output for subwoofers and is often labeled 'SUBWOOFER' not LFE. 5.1 channel programs on DVD discs have a dedicated .1 channel output with bass-only content that is best reproduced by a subwoofer. Connect the output of the LFE or Subwoofer jack to the Line In jacks of the subwoofer using a single RCA cable (the two jacks on the left in the photo). A 'Y-Cable' may be necessary to connect the LFE output to both the left and right channels of the subwoofer.
2. How to Connect a Subwoofer to Speaker Level Outputs Some receivers and amplifiers do not have an LFE or Subwoofer output. In this case you can use the speaker outputs of the receiver to connect the subwoofer. Using speaker wire, connect the left and right channel speaker outputs of the receiver to the left and right channel speaker level inputs on the subwoofer (the speaker inputs on the right side of the photo). Using speaker wire, connect the left and right channel speaker outputs on the back of the subwoofer to the left and right channel front speakers.
