Nice experimenting and photography. We'll have to chip in and buy you a flexible endoscope.
Perhaps a 2-part foam would cure better in a sealed bag? I've been looking at the foam that
Tap Plastics sells. I have a store local to me, so I was able to play with a cured sample. The stuff is quite rigid when set up. (I was thinking of using the foam to created a "form" for a fiberglass enclosure that would fit down into the battery box.)
Man, the opportunities for amusing foam accidents are almost unlimited.
Mix too much and it might expand to fill the entire MINI! Seems like you might want to do something like this:
- Place a bag in the area where you want the foam "bulkhead".
- Use some chunks of squeezable foam or something to contain the bag, fore and aft. Perhaps the stock "dam" can be used. Duct tape might also help.
- Locate someplace where you can pour the goop into the top of the bag,
and make sure you're prepared to deal with the extra foam that will come squirting back out!
- Once the foam is set, you should be able to remove some of the bag and if necessary, carve the foam into its final configuration. (I'm sure it will have bulged in places.)
- You might want to "paint" some extra foam goo around the edges of the bulkhead, to make sure the foam is sealed to the metal. Maybe do some syringe work to fill gaps.
I don't know, but I suspect that six inches of this foam would be fine as part of an enclosure. It certainly won't be heavy like MDF, but if it's airtight it oughta give you some nice damping qualities. You'll probably want to put some acoustic stuffing in the chamber anyway.

How long will the battery run your stereo with the engine off?
Not sure if this was directed at me and my tiny battery, but if it was: The small battery only has about one third the amp-hours of a standard batt. So, I'd only get about one third the time. (I figure I'll need to be careful about that sort of thing. The battery will be more than adequate to start and run the car, but I won't want to run a lot of accessories with the car shut off.) Another reason to go with super efficient amps...
