Need help with RCA voltage issue....asap

[RCwhat 10+ year member]

hey guys, i'm currently almost ready to light my truck on fire from frustration. //content.invisioncic.com/y282845/emoticons/mad.gif.c18f003ab0ef8a0d9c27ca78d77a6392.gif So here's my problem. My sub amp comes on but the subs don't play. I measured the voltage at the rca's and got zero, tried it on the highest AC and DC settings on the dmm. everything else is fine, the deck works, amp comes on, but no voltage at either the rca's or the amps speaker outputs. Then i tried a different deck. I removed my p860 (yes i did turn the sub out put on, also tried other two sets of outs as well) and tried this old *** sony 2180 pos and the same exact thing. Remeasured voltage at rca outs on each deck while playing and both read zero. I also tried different rca's with no success. Are both decks junk or am i missing something??? There IS supposed to be voltage at the rca's while the deck is playing correct??? Please help, I'm thinking about going down to best buy and picking up an alpine 9851 //content.invisioncic.com/y282845/emoticons/yumyum.gif.0556df42231b304b9c995aefd13928a8.gif if i can't get either of these decks working.

ok--i'm not trying to be a smart *** here but did you have the rca's plugged into the amp when you checked it? some ppl unplug them and i believe if there is not a full loop then the deck won't send signals.

yeah i tried measuring it about everyway i could possibly think of.

i would check the rca's at the output on the deck while its playing and while the rcas are plugged into the amp as well.

edit" nvm i just re read the post sorry. not sure what else to check since you seem to have the other approaches covered.

fvck it, i'm going to bb and getting the alpine and see what happens... i wonder what their return policy is if it does the same crap.

FYI: when i trouble shoot a problem with RCA's i unplug them from the HU and touch the center prong, the speakers should make a buzzin noise when you touch it due to static electricity. Doing that saves you the time and effort from taking out the RCA's and all that good stuff.
