Helllo, i accidently rippes Amp con cable from my head unit, or maybe from iso cable, not sure where it was coming from.. the thing is that amp con wire is not connected anywhere so i just connected it to antena cable... it works, but is it safe? I wont destroy my head unit after some time?
If it supposed to come from iso cable is it possible to buy just iso wire separately? Without buying new head unit?

Hi，
the "AMP-CON" is connected to the amplifier or radio adapter or to the antenna which auto rise and fall.
If there is no such device in your car,you can let it alone or free.
You can contact the customer service to get the ISO cable separately.
