this very much depends on wether or not you are looking to keep the stock door panel or give it a custom look. if you want to keep the stock door panel the kicker RMB8s are a very good choice and will mount behind the stock grill. you will need to seal off the front from the back of metal door panel to get the best results. if youre looking to get a really good 8" in the door its gonna take a lot more modification, add weight to your door and require a custom door panel to be made. the RMB8s are really nice to free air application, just be sure the front and back waves are blocked from each other.
