Tapping power from the door lock circuit is how I installed the stereo in my car.  It is likely that you read one of my accounts of this in the various archives.  The arrow points to the new connection I made.  Both sides of the circuit breaker have spare 1/4" male spade lug terminals available which are rated at 20A ala Lucas.  Here I used the output side.  (Damn it's nice to just walk out to the garage and snap a photo.  I still have a lot to learn about the finer details.)

Almost exclusively, stereo equipment manufactures recommend tapping power directly from the battery.  This is because many customers don't understand the difference between a solid high-current connection versus powering a whole system from a strand of phone wire.  

My opinion is that adding unnecessary connections to a corroding battery terminal will compromise the reliability of the car.  It will also make it more difficult for other mechanics to figure out what you've done and not bugger it up.
