Switched 12v "wakeup" line for subwoofer amp?

[asktoby]

Does anyone know the best place to pick up a 12v wake up (I think this is sometimes called "remote") power feed that I can use to power up my sub amp when the ignition is on, and power it off when the ignition is off?

To be clear: The main power for the sub amp will come on thick fused wire straight from the battery, i.e. permanent 12V.

I'm looking for something very low current just to pull the wake-up pin on the subwoofer amp to "high" 12V.

The sub amp will be in the estate boot, but if there's nothing at the back of the car I can pick it up from behind the dash and run a wire through...

How did you get your singal from the radio unit to the amp? How did you tap in?

You can tap into the rear speaker wires behind the headunit,using a RCA convertor
