2011 base Pioneer HU turn-on wire for amp?

Hi everyone,

I have a 2011 xB with the base Pioneer head unit. This unit has 2 factory subwoofer outputs (mono, the manual says) so I'm toying with the idea of running one of those outputs to an external amp that would power an 8" subwoofer in a sealed box under the front passenger seat. I feel that the centrally located sub will provide a balanced thump to all the passengers.

So here's the question: does anyone know what wire on the head unit I can tap into to provide a +12v turn-on signal for an external amp? Thanks in advance for any input.

firstly, bass is a unidirectional tone, so essentially it doesnt matter where you put the sub, it would be heard the same.
