I can solve this problem by turning the volume on the sub all the way up and then turning it back down to the level I would like. It will however cut out again in a few minutes. The entire time the sub is correctly passing through audio.
I have recently discovered that if I keep the sub volume above 50% then it doesn't cut out at all. Also I have noticed that if I press on the volume dial, then it will cut out.
The sub should still be under warranty, but I'd like to avoid shipping it somewhere fore repairs since shipping is expensive and the sub was pretty cheap to begin with.

What constitutes "good soldering skills" ? I've soldered the wires on some fans together to run them off the same controller and extended a few wires that wouldn't otherwise reach the motherboard headers in my computer. Anything more complicated than that?
I've looked at changing the volume pot on my amp, but once I opened up the amp it looked like it was soldered to the board and I would need more specialized tools then a regular soldering iron. I'm a little afraid that the sub will be the same.

The solder should be nicely liquified all the way around the pad and it will try to "cling" to the metal bits due to surface tension. Then, as soon as the connection has gone fully liquid, remove the heat and let it solidify naturally (i.e. don't blow on it to speed it up).
