No voltage from the sub preamp?

[QUOTE="Zimmerru, post: 8437784, member: 667473"] I have a dual xhdr6435 (not a great radio but it works) and I'm trying to hook up my amp to it but when I checked the preamp with a voltmeter (to figure out which wire on my RCA cable is positive) I am showing no voltage with the radio on and turned up. I set the voltmeter to 200v AC (its lowest AC setting) but I'm not seeing any reading when checking either of the channels. Is the preamp shot or am I missing something?
