I recently got a set of component speakers installed in my Chrysler 300 by a car audio shop. My front right door speaker is producing no sound but the tweeter is... Would anyone know how to take off the door panel so i can see if a wire is somehow unplugged?... I didn't buy my speakers at that shop so I dont want them to remove the door panel and blame my product and charge me for checking it out...

Any help is GREATLY appreciated and thanks again
