They have like 3 different models of the 8". Go on the website and see what you want, the 8W3 is much easier to fit because it has a much smaller enclosure requirement and you can put about 4 of them in it. The 8W7 , you will be only able to put 2 of em in due to the sub size. I think if you have the center console, you probably could modify to make it fit underneath by ditching the bose subwoofer. I would like to try that route if it works.
