Do I need a specific type of 4 gauge wire for my monoblock amp?

I purchased a JBL BP1200.1 monoblock amplifier, for the subwoofers in my Cobalt. It did not come with any wiring. There are 3, 40amp fuses on the amplifier. I think that means that the power cable that I hook up to it, needs to have a fuse that is at least 120 amps. I ordered an amp wiring kit online, and it comes with an in-line 80 amp fuse. 

My question is, can I buy and ANL fuse holder to replace the in-line fuse holder on the power cable? And do I use a 120 amp ANL fuse, or a 150 amp ANL fuse?

To handle a 150 amp load youwill need a awg-1 gauge 
in a copper wire ,justlook up the awg wire index for 
150 amps and wire size requirement . Something does not sound right ,this is not for a home ,  even on big power amps 
they use only a 20 amp circuit .i owneda Audio store In the UK
and into Audio over 30 years . Something is not right ,
thereos no home amplifier higher then a 15  maybe 20 amp fuse .
you need to tell us what model brand  and age 
call JBL . If this isaindustrial Amplifier for a outdoor concert 
that is a whole different ball game.

120 amp fuse  that  is higher then the current going through any 
wire in you home. Most houses have a 200 amp service for the whole house. Is this amp for a Stadium ?  I have never seen in 
Audio ever a 150 amp fuse
