I've got doors for a 1990 Dodge truck. Full height plastic door panels. They have built in speaker grills at the bottom and the doors have speaker cutouts.
What size speakers are usually used? The holes look like 6.5"x4.5" - I was wondering if anybody has installed 6"x9" speakers in their doors...?
Where else are good speaker locations? I would like to have four decent speakers that aren't an eye sore
