I'm getting no voltage reading at any of the external outputs. I have a JBL 8" sub fired by a Kicker dx125.2 and it works fine off the factory installed Jenson (junk, I know, but it fires the sub setup just fine when watching movies.) I read 2 to 4 volts on AC read when I disconnect the input from the amp, but at the back of the Kenwood (it's new and sounds great) I'm reading .004 (also on AC) at all 6 connections. Is there a setting in the menu I can''t find that needs to be turned on? Thanks!
