252chevyboyz Posted July 4, 2012 Author Report Share Posted July 4, 2012 Thanks for the link and I have read that and tried then re-read it and tried again but still couldn't get a voltage. I have been trying for about a week now to get the voltage with my DMM. I am playing a 50hhz tone on repeat so the signal won't change also. Maybe I can figure it out this afternoon. Ill just keep messing around til I finally I get it to work. Any tips?

252chevyboyz Posted July 4, 2012 Author Report Share Posted July 4, 2012 Well I just sat out in the car at the amp for about 10mins trying to figure out how to get a voltage reading off the rca's. I had the "how to" thread pulled up on my phone reading through it as I was at my rca's. Still no luck went through all the AC settings on my DMM (Greenlee DM-20) and got nothing so I tried all the DC settings for the heck of it and nothing either. Should I just try to check it on the back of the HU itself? Not sure what to do here. I know the center pin is postive and the sheild is negative. Would I have to put both pins on the positive lead and both sheilds on the negative lead?

graham0599 Posted July 4, 2012 Report Share Posted July 4, 2012 Did you try both RCA's? Maybe one is bad Quote My 350z build- http://www.stevemeadedesigns.com/board/topic/174424-2008-350z-build/page-2?hl=%2B350z+%2Bbuild#entry2605678 Link to comment Share on other sites More sharing options...
252chevyboyz Posted July 4, 2012 Author Report Share Posted July 4, 2012 Yes sir sure did. I tried the right and left channel but still no results. I got a spare set of Q Power RCA's that have never been used if I need to take my dash apart and put those in. I can turn the truck off and plug them back into the amp again and it plays just fine so I'm still gett signal through these rca's Quote - 1997 Chevy Tahoe- Big 3 (1/0)- Dual Autocraft Batts- JVC KD-A315 HU- AQ 2200.1D- 18" AQ HDC3- Box w/ Removable Port (6ft^3 @ 36hz & 6.7ft^3 @ 42hz)- 39' 1/0 & 13' 2/0 Flex-A-Prene My Selling Feedback Build Log Link to comment Share on other sites More sharing options...
graham0599 Posted July 4, 2012 Report Share Posted July 4, 2012 Try checking the voltages straight from the HU.

252chevyboyz Posted July 4, 2012 Author Report Share Posted July 4, 2012 Ok just took my dash back apart and pulled the HU unit out and checked AC first and then tried DC and got nothing on either one again. I saw the little connecters or contact plates inside the rca jacks on the HU and made sure the positive lead from the DMM was touching these plates. I put the negative lead where the sheild usually touches.

252chevyboyz Posted July 5, 2012 Author Report Share Posted July 5, 2012 Anyone got experience retrieving the RCA voltage on the HU or straight off the RCA's?
