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?
A couple of things to try:
1) If it's on a power bar, turn it off at the power bar and wait a few seconds and turn it back on.
2) Remove the driver and see if there is any sort of loose connection (would give you green light no audio).
3) Double check the voltage (110V vs 220V) on the back of the amp that it didn't mistakenly get switched.
