I do t get what holds the fuse in, its loose and will wiggle out over time, what am I missing?

If you look at the picture, you can see the red power cable. At the very top center of the picture is a gray plastic container (approx 6-8" from the end of the power cable). That is the fuse container. The fuse is inside and can't wiggle out.

How much speaker wire do you get?

Kit includes 17 feet of 8 AWG power wire, 3 foot of 8 AWG ground wire, 30 feet of 16 AWG speaker wire, (1) 16 feet twisted pair RCA, AGU fuse holder and fuse, 20 feet of remote wire, 40 Amp fuse.

Is this enough wire to run for a f150 supercab ?

I am inclined to say yes, but to be sure, you should measure. You need to figure out where you are going to mount your amplifier, and how you plan on routing your power cable. There is 17/18 feet. of Power cable provided, so this is usually sufficient... but I would measure just to be safe.
