Kenwood DDX-790 miswire DC error

[Greggk 10+ year member]

ok, my buddy has this reoccurring error message pop up. I DID NOT INSTALL THIS. I am merely trying to fix the issue. Last time, I rewired the harness, and it went away for about a week or so. Now yesturday it popped up again. What am i missing here? We are both military and we go on our post deployment block leave starting this weekend, so I want to make sure his radio works for his long drive from Fort Stewart GA to Wisconsin. Please give me some insight.

what kind of vehicle? if you have a dmm double check powers grounds and ohms of the speakers. Also make sure there is no continuity between speakers and ground.

did you use an interface piece or is the acc wire ran to the fuse panel.

it was a harness adapter kit from crutchfield

if its one that has a box that you stash behind the radio then I would try this. Disconnect the acc wire from the radio. Wire a relay to trigger off the acc wire coming from the box. use the 12v constant as a source for power and connect the radio to the output of the relay.

yeah it has a little box.

just as a side note, this truck has had the same subs and amp for a few years but he had a headunit, components and coaxial's installed while we were deployed, so i am afraid I will have to rip the interior apart to try to find the culprit

if it was installed at a shop I would talk to them first. Could be covered by warranty.

had the headunit been reset?
