After finally getting round to putting my old audio bahn eq and rockford amp/sub in my motor I'm a bit puzzled. I've spliced into the remote on wire used for the OE sub in the boot, but it seems to turn everthing on with just the ignition even when the concert HU is off.

Is there a true remote on available on the HU and if so which wire is it. I've used the black and white striped one.
