4 inch in the dashboard, 5 inch (yes 5, not bigger) in the rear. Polk audio makes these sizes in reasonably priced quality speakers. Not enough bass for my taste, I cut a hole in the deck and put in an 8 inch free air subwoofer with an amplifier mounted in the trunk. Sounded great. Now I have a 94E420 with an entirely different stock stereo setup, not sure how I'll use these components (including a Sony head unit and Sony CD changer) in the new car. Any suggestions anyone?
