I have a 1990 lx 5.0 hatchback and would like to replace the factory speakers, the dash speakers I know are 3.5's the doors are 5.25's and the rears are 6x8's I think, if so can I install 6.5's in the doors without having to destroy the factory grill and 6x9's in the rear. My mustang has all black original interior and I do not wish to "cut or trim" anything unless it's behind the factory grills as to not take away from the "factory" look. Any help on this would be greatly appreciated.
Thank you,
Andy
