I just recently received a Synergy SUB-12 from a family member. It's in great condition but upon powering up seems to produce no noise at all. I've tested it every way I could think but the sub will not move even though the LED indicator is solid blue (a.k.a. receiving a signal unless I don't know how to read). I'm a little uneasy tackling a soldering job this large/precise, and would like to just buy a replacement plate amp or external amp. Does anyone have any suggestions based on the power requirements of the original amp? Ideally I'd like to avoid the headache of having to rip it apart and try not to destroy the existing board. Looks like BASH Klipsch replacements or the BASH 300S are both around ~$180... Any help would be greatly appreciated!!!!! - Will
