4x6's in the doors, 6x9's in the rear deck

The front doors can easily accomodate a 6 &1/2 inch speaker. All that is required is a new mounting plate. You can make two in less than 1/2 hour. Use the original one for the factory 4x6 as a guide and cut a new hole for the larger speaker. The sound quality is far greater and you don't have to modify the door at all.
