Fuse 85 in the passenger footwell fuse box is switched on/off with the IGN power. I used a fuse tap on this fuse to power the remote in lines on both my amp and my computer power supply.

Just know that if you use this fuse, the power turns off when you turn off the car. This means that the music will cut out as soon as you turn off the car, not continue playing until you open the door like it does now.

Also, this means that you will have to have the car running to use the radio, as it is IGN switched, not ACC switched.

I would have preferred to use an ACC switched power source, but I all of the ones that I could find were like the 12v car outlets in that they did not actually turn off until ~10 mins after the car was turned off. I decided I did not want the extra strain on my battery by having my amps, etc. run off of battery for 10 mins after the car is "off".

Good luck! Let me know if you have any questions.
