20 Most Recent JBL S120PII Subwoofer Questions & Answers

Generally there is a left and right input. The sub is usually not in stereo, the frequences of the sub are more omni directional, and have no spattal placement in the stereo field. If there is only (1) input you can take either the left or right from the system and you should get the frequencies you need. In the even it is not working out quite right you may take the left and right and use some 1k to 4.7k 1/2 watt resistors connected to tie the left and right line output togeather to feed the sub.

Sounds like a fuse issue in the power from the amp - the remote circuit could be and probably is completely independent. haven't been able to find confirmation on this, but if you are confident to take the cover off then check (probably)around the area where the power terminals are there may be some fuses. Hope this helps, ask again if not :)
