You're gonna have to trouble shoot. Since the sub is the new thing, look there first. Check all connections first. An almost unplugged preamp input or even a funkified speaker connection could...

people are talking about a reference level of 103 or 105 or 106 dB, so it's a little disingenuous to simply say nobody suggests setting ref at those levels. Reference level isn't the max. Maybe a...
