I have a 2004 hemi standard cab. Viper truck hood, Volant cold air intake, Gibson headers with 2-1\2in exhaust to dual back 2-1\2in pipes. i have the infinity audio system. everyone keeps writing about the door panel speakers being 6x9 but i would like to be sure the they are because from the look to me they seem to be 6-1\2in woofers. i also would like to know what size are the rear panel speakers.

 

The door speakers are definitely 6x9. It's only the grill that's round. Check Crutchfield for the rear.

 

front are 6x9 and rear are 5 1/4 take off the seat belts then the top cover then the bottom cover to reach the back rear speakers.
