The holes might be a little off so you might have to drill new holes. I have Infinity Kappas 6x8 in my doors and love the hell out of them. The only thing is if you do decide to put speakers in your rear deck, you are going to have to top mount them. The reason is because there is a layer of foam between deck cover and deck itself. You wouldn't be able to hear the sound. This was covered in another thread recently also. The sound will be muffled. I know a lot of people want to bottom mount them because they don't want to take a way from the factory appearance of the car. Unless your car has the sub system or already speakers mounted there, that's the best way. Unless you want to fabricate your rear deck so that sound can pass through some way.
