how to remove interior panels

just wondering how to remove my interior panels on my 2001 xtreme ext cab third door? i am trying to run my RCA'S power and ground for my AMP. also can i mount the amp on the back wall of the cab?

As far as panel removal, most vehicles have plastic body panel clips that hold the interior panel to the vehicle. These can be pryed off using a standard door panel remover available at almost every autoparts store and sears. Look for plastic caps that when popped off there is a screw underneath, especially along the floor.
