Mines not mounted to anything. A solid built box won't need to really be secured (unless your worried about it being stolen). If its pretty heavy it'll sit in place.
FWIW, You don't NEED Polyfill, you can fill it with some fiberglass insulation. Never stuff it full of the stuff, just put enough in to take up the space while still fluffy. I've seen tons of guys fill them so full that they can barely get the sub in.
Looks like its coming along well.

What do you need 6 tweeters for? 2 is all your going to need in a regular cab. Your just getting a bit overkill in the 3k to 12k Freqency range. More speakers isn't always better. Quailty is where it counts.
