Ok I have a 4 ohm head going into an 8 ohm cabinet..I belive this isn't safe I have only used it a total of 4 times for less than an 1 hour period.

It's going into a 4x12 cab is there any where I can find a re wiring model I searched google and found results im just not sure which one to go from.

Well if its 4x12" cabinet and its got 8 ohms alltogether chances are each speaker is 8 ohms.

You could only use 2 of the speakers in there wire in paralell and get the 4ohms you need out of it.

Will there be any volume decrease my cab handles 400 watts and I have a 200 watt head, is it even dangerous to be doing this?
