Amp not switching off

[Ronin]

what about using a relay? maybe leakage current of that switched ignition intended for bose is too much for the converter and the amp?

I like the sound of that however could you dumb it down for me please . Electrics and associated terminology isn't my strong point so i t can take me a while wrapping my head around what needs doing. What sort of relay am I looking at and am I right in thinking to put it on the said switched live going into the Bose amp? I've just had the Headunit back out too just incase there was anything glaringly obvious there but there are literally no cut or exposed wires there as I used everything plug and play.

You get a 5.99 relay from halfords:

connect ground from bose connector to pin 86 of relay
connect constant 12v from bose connector to pin 30 of relay
connect switched ignition from bose connector to pin 85
connect pin 87 of relay to aftermarket amp's trigger input.

This way you get no residual current and relay will 100% switch off with ginition off. If it doesn't you have a fault.

Thank you, thank you. Just to confirm, pin 87 going to the subs remote turn on which is currently connected directly to the Bose switched live ?
