Jvc unit KW-AVX840 miswiring check and reset error message i have only connected red+yellow together then a ground(black) by it self tried 2 harn. still showing error message

SOURCE: re sent wire diagram gat all messed up

Hi
have we spoke before in previous post?
the red can go to any 12v live peramanent such as wire to clock or other item that has power with ignition off and the same with the yellow if your putting these to the same permanent live say from clock you can join these to together red/yellow to red on clock
the black can go to any metal or neg wire.
This should then have your device working the only problem im looking at for you now is the pink wire as this stops you using the device whilst driving as it goes to handbrake but i need to find out if its live or negative.
You could just wire the red/yellow to live and black to earth then see if it switches on and works if not then let me know and ill see about the pink wire ok
Makes sure you use inline fuses on the live wires so as not to short the device out.
Make sure you know what is permanent live to put the yellow/red wire to.
It doesnt need to be ignition it only says this so you cant use it with ignition off but you can wire it into any live feed from clock or switches so its up to you what to wire it to its just the pink wire im concerned about.

PINK: does it tell you to put it to live or earth on handbrake switch?

let me know ok

SOURCE: kenwood kdc 3011 rests its self every time i turn the car off

This means that the power lead you connected the red and yellow to is a switched live and each time you turn off the ignition the power goes off and therefore resets. to fix this problem you need to connect the yellow to a permanent 12v supply that stays live when you turn off the ignition.

I had this same problem...you probably have the wires wrong. Double check your connections for the red and yellow wires from the headunit. Make sure that your red wire is going to a 12 volt source that only switches on with the ignition.

Hello pmdharan, It sounds like the subwoofer is not turned ON. Go to MENU ITEM > SPEAKER SIZE >SW (subwoofer) and select ON. Hope this helps.
