It could be possible but I don't think thats the problem. Where the speaker and the plastic casing meet there isn't any room for the metal wall to fit where the speakers are suppose to sit. Plus even if I get the it to fit properly the speaker grill won't sit flush because the speaker sits to far outside the casing. I don't know how the speaker can fit unless its mounted without the plastic casing I may try the way the guy did on the SLK on the PDF file someone posted. I've replaced the foam rings on my subs twice now that why I was going another route with higher quality subs.
