I may have mis-interpreted the photos, but it looks like at least some of those containers are for mid-range/low range speakers ? Subwoofers have specific parameters for sealed boxes and work well in that configuration, but most 5-6" woofers and mid ranges are designed for "infinite baffle" or free air mounting. Placing a typical speaker like that in a small enclosure as shown can significantly affect the audio performance in a negative way. If that one set of speaker boxes are mounted in the 1/4 panel or kick panel, I would encourage you to open up the enclosure to an airspace that does not acoustically connect to the interior.
Fab looks great though. The fit on the gill replacement panel is unbelievably tight. Still can't figure out how you experts get from the weld to the smooth panel and make it look like it was never touched though.
