I purchased the 350 back in August and it appears it isn't working anymore. I checked it with another receiver to make sure that wasn't the issue and it still doesn't work. The green power light on the back still comes on but I am not getting any sound out of it. I checked all the settings on the receiver and they appear to be correct. Am I missing something? Could it be a fuse or would that not allow the power light to be on? If I leave the sub on all the time would that harm it? Any suggestions before I send it in?
