I have the best install for everyone to do. I did this in my 98 Trooper, until I moved the speakers to my Vehicross. I used some Infinity 61/2" components. The components are the key. Since the woofer doesnt have a tweeter suspended in the middle taking up space, the 61/2 can be mounted in the factory hole with no chopping, and the factory cover used. They have to be pressed in pretty good, but I never had them pop off. they did bulge a slight bit due to the metal around speaker, but not too noticeable. the 3 mounting screws do need to be drilled in the plastic though. speaker depth must not be too deep, so compare different models. I just velcroed the tweeters high above the back doors as you can run the wires behing the plastic to them. the crossover box for the components i double taped in the speaker hole under the speaker. The job sounds great, but that location just has horrible bass response location wise no matter what. I would recommend some dynamat at least a little in the hole. If anyone is unsure if a certain speker will fit, I would recommen secondly to use a 5 1/4 component, and least a 5 1/4 2 way speaker, although it doesnt matter greatly at all except optimum tweeter placement with components. Good Luck
