Ok, I would really like to know the answer to the question that I asked. I have already tried the other routes and have yet to see any box for the tC that fits as well and looks as good as the optional Bazooka enclosure. So, like I said, I would like to know the mounting depth. If anyone who knows the mounting depth would like to tell me, or if anyone who has one would like to be so kind as to take out the sub and measure the depth from the inside of the opening to the back (bottom) of the box, I would REALLY appreciate it.
