On a 2009 Chevy Aveo non-hatchback how do I take off the door panels to acess the speakers?

Im installing a new sound system in my 2009 Chevy Aveo non-hatch, and there is no apparent way to remove the door panels or the dash/ default radio. Pictures if possible but not necessary. Please give your source. Thank you.|||http://www.crutchfield.com/m_399/Car-Spe鈥?/a> This site will help with your speaker replacement.Best of luck.
