The sub was working just fine then all of a sudden a real loud distortion starts, no matter if i turn it down it stays really loud then cuts out. Now I cant get it to work. The power light stays on and every once in awhile the distortion will come on then nothing again. Any ideas?

your speakers were sitting to close to sub woofer and what happen was when puttind to batteries together what happens they move away from each other you blew your sub woofer the only thing to do now is replace subwoofer.
I had the same problem although not in storage but it just lost power to the console. It turns out that when I press down on the cable connecting the sub woofer and console, at the back of the sub woofer, I temporarily get power to the console. I did that for long enough to eject my DVD's and then opened the back of the sub woofer to fix it and cracked the board and broke it forever.
Hiya, start by checking the power cable, then check the fuse in the unit on the pcb. If blown, replace and if it blows again then problem could be either Power supply or the amp outputs. If it doesnt blow, stays on but no sound, problem also likely to be output stage. You will need someone with experience to check outputs, etc and a meter though. Hope that helps a bit. Best of luck
You didn't say is your sub active or passive.If its active first check signal cables from theater system,power line of the sub, it has to be the same phase as the system.If its passive take a voltmeter disconnect the sub from the system and measure for DC voltage on the SUB output on the system when its OFF.If DC voltage is present your amp is damaged.It can also be that the preamp circuit for the sub doesn't mute the input when unit is on stand by and you hear frequency of your power supply (50-60Hz) on the sub
