HU on and off on and off

Post by MrSo0h0o »

for some reason while i was driving around today my HU just began to turn on and off uncontrollably, as if it were having a seizure. i checked in back of it to make sure no wires are loose. no amps connected to it, just the HU, antenna wire and the wire harness. dont know where my ground is or if it is even that. any ideas?

Sounds like a possible ground wire problem.

Check the pins on the faceplate and on the deck itself, if they are dirty and not making a good contact this can happen.

Just try looking behind the the head unit and find a black wire that is screwed into some metal of the car.
