I have a JBL SUB160 subwoofer. I was playing around with moving it to a few new locations today. Every time I moved it,it worked fine. Then, on my last move I sat my Yamaha receiver on top of it (along with a few other components), turned it on... and nothing! I'm using the LFE input, but I also tried the high level inputs and still nothing. Do you think moving a receiver (a.k.a. big magnet!) caused my sub to stop working? The power light on the sub still comes on (green), but it acts like it is getting no input. If I turn the volume of the sub all the way up, I get nothing (no humming). I've ried about every combination of inputs (all confirmed working) to the sub, and nothing...

Help!!

Thanks!
