Yeah it does look that way. It doesn't move though. Triple stacked baffle, double stacked every other wall, and braced with some large dowel rod. Everybody says it's hard to get a good number in a Trailblazer. I did a 152 at 35hz with no in depth testing or tweaking.
Can't wait to deaden, get an alt, and throw in my other CS 5kw. Should start getting nasty then.
