Looks good!

I actually like fiberglassing, lol.

Also, as far as the video, I'd say that inverting subs in 4th orders is more common than not. A lot more than 10-20%, unless you were talking about installs in general. Yeah, most people with subs in the trunk just mount them normal. Inverted is best in 4th orders though, because you can smell coil when subs are stressed, there is better cooling for the coils, and you can more accurately calculate the sealed section.

Let me know how it sounds when you're done! I'm also making a bandpass
