Q: I desperately need to replace the two front speakers of my 2003 Nissan Altima. I need very legit instructions to do this procedure. Please help me find these instructions because I do not want to make one mistake.

A: You will need to remove the door panel. Start by carefully popping out the window switch. Then in the pocket where you grab the door to shut it there is a screw. It may be hidden under a thin piece of plastic or rubber. After you remove the screw just grab the bottom of the door panel and pull. It will pop off. It is held on by plastic clips. You now can get to the speaker. Remove the screws that hold the speaker to the door. Assemble in reverse order.
