Will a sub produce a hum if it is turned up too loud? I only turned it to the 9'oclock setting like it told me too and I got a very loud hum. If I pulled the cable out It was gone, but that kinda defeats the purpose now don't it. When I turned it down to around to about 6 or actually lower it would get a lot softer obviously and not be noticable. How low should I turn it to get the calibration done correctly. Another thing. When I calibrated it using the auto setting it did not sound loud at all or produce much of anything. I know my other sub which was a tiny little thing would be much louder and quicker with its sound during calibrating. Is that a sign that something could be wrong with the new one?
