Here is the email I just got today from JLAudio. I am hearing all kinds of stories and I dont know who to believe. I would love a 10in sub in my X. Here is the email:

Dear Mark, We are not working a Stealthbox for the Xterra. We are interested in looking
to do something for the Xterra. If we do decide to offer a Stealthbox, it will be till next year.
Thank you for your interest in Stealthbox.
