Has anyone installed a set of 6X9's in their stock hatch speaker areas? How did it work out? Would you happen to have a write up or could you make up a write up on how to do it? Did you have to custom make a box? What did you use to make the box? I'm thinking of trying to squeeze a 6X9 in that area and am hoping one of you guys has had success with it before. Lastly, any tips that you could think of?
