Unfortunately that depth is too large or I would definately have done it! My current sealed box is just about as big as I could cram into the trunk; I had to put it in first before mounting the subs (god help me if i need the spare....)


Just to clarify you are saying that each side of the current enclosure requires a 4" X 13" circular vent, or that the enclosure need four total, two on each side? Do I have to worry too much about having a smaller volume than Diamond recommends?

Thanks for your help, I am pretty excited about venting the subs. They sound alright now, I can't wait to hear them ported!
