We have had this speaker system in my class for like 4 years now and we finally hooked them up. The volume control knobs work backwards and the satellite speakers play but with low volume (though the knobs are turned completely to "Min"). The subwoofer does not work at all and only a small click can be heard when the power is turned on. I took them home and took the back off the subwoofer. I looked around the circuit boards and found a fried resistor (or at least I think that's what it is). It is on the board with a lot of large capacitors, and I'm pretty sure it connects R120 with J113. Now I have no experience with internal electronics whatsoever, so any details on what to do will be helpful when asking somebody more professional than myself. Thanks.
