****..i know this is a rookie *** question but i gotta say ask anyways.. i was installin a jvc head unit yesterday to my civic hb....the head unit was working fine when i took it out of the person's car i bought it from i installed it in mine and now the thing wont turn on... i checked all the wires and they match up correctly and im using the harness for that car so it should be simple. last night it turned on but with no sound it now today it just doesnt turn on at all...what could it be?

i'm pretty sure you switched the memory wire and the actual power wire. The memory wire always sends a small amount of power to the hu so it doesn't lose its settings, but the power is what you need to actually turn it on. Try switching the yellow and red wires.

i checked that ...all the wires are in the correct spot though...im still not getting the 12 volts to the wire harness and all my fuses are good

really couldn't tell ya, you could run a power line directly from the battery to the hu, that would do the trick.

does the yellow wire or the red wire have 2 volts. just run a new constant or switch from the fuse box or from underneat the steering column
