i have put the remote wire into the back of the headunit for the amp but it stays on even if the headunit is off which is no good to me so i have had to remove the live and stop it working for the moment, what wire should the remote wire lead be on, or should i just attach a switch to it? although my headunit can be switched on without the ignition in and does not switch off with the ignition. can anyone shed some light onto this?
