Stock amplifier loses power when door lock button is pressed. I bought the replay that is needed, but do not know where it is located.

Hello,

I do not see a relay in the system, but I do see the convenience center and VSS inputs. Here is a wiring diagram for the radio so you can see how the system works. This guide can help as well.

Check out the diagrams (below). Please let us know what happens.

Cheers, Ken

Thank you, turns out door tweeter cable was loose and touching metal on the door causing stereo to go on protect mode. Diagram was very helpful.
