I am planning on slowly upgrading my stereo. I first plan, for christmas, to get 4 new speaker for the doors. Correct me if i am wrong, but the rear speakers are 5 1/4" right? ('99 Ram QC 5.9 4x4) But i am not sure what my front ones are i just looked throught the slotted holes in the doors and they are definitely larger than the rear ones and look oval. Does anyone know the size of the fronts?
