ok, yeah... then you'll probably need to make up two rings to extend the subs out a little bit. Shouldn't be a problem. Are you gonna go with the W3v3's? Because if you are... That is gonna be awesome. We built a custom enclosure in my brother's F-150 last summer. 2 of these bad boys and man... if your box is tuned as well as we tuned his, then you're gonna need s lot of Dynamat and make sure you tighten down your rear-view mirror. His is so loud that it will move air in-and-out of your chest if you just open your mouth. haha. I have one of em and my rear-view mirror fell off the other day while I was driving. (But again, we do our boxes custom tuned to get the most out of the sub. A one size fits all box may be different)
