Yes you will need to take out your headunit and run a wire from the remote turnon lead from the headunit, it should be a bluewire with a white stripe but they might have a diff color on the sony, but I doubt it. Look at the wire diagram for your headunit. Then run the remote turnon lead to your remote switch on the Sony Amp. This will make the Amp only turn on when you turn on the headunit. It will turn off when you kill the car or turn off the headunit. I hope this helps and good luck
