What size fuse for this amp? And is this enough wire?

[Dragonsyph]

Just got a skar 150x4 at 4ohm and was wondering what size fuse to use from rear battery to amp?  

Using 4g wire from skyhigh, I usly fuse for the wire but this is right before it goes into amp.

 

 

side question, is 2 runs of 1/0 skyhigh from front to back enough for sundown salt 4 amp that puts out 6000 watts plus the skar amp thats around 600?

Use whatever fuse the manufacturer recommends. Yes that is good wiring if it's ofc/ofhc. If it is CCA then no
